    The holes are laser cut. Highly precise and made available to custom order sale. Made using flat stainless steel and then bent to form the more desirable square shape. I will also be making some ordinary piped ones.

    I have been reading this thead with eagerness and waiting for aesthetically improved design. This one is not bad. But with the big bazooka diameter, can the water reach the top holes? How big is the pump needed to power this bazooka? Or should it be placed horizontally? pls update us once it has been tested bro. Thanks.

    Hi TS Lau,
    I am turning green with envy when reading the postings on how you guys have achieved chilled water. It nearly cost me a leg and an arm to buy the Artica chillers but definitely a leg and an arm when monthly electricity bills have to be paid. Well done.

    Salam Dato' DRA,

    Finally, a very much appreciated consolation from a well experience Chiller Guy towards a spray bar DIY. :-D Hee..Hee...

    These respect each other 'ness are most welcome indeed... Motivates us really.

    Nevertheless, the Battle of TOR-X™ vs Chiller will continue till reach winter temperature here in Kota Bharu...KaKaKa:-)) Tq

    Bro James,

    You can have those Torna-X name for the cute s/steel for free...

    Bcoz my TOR-X™ achieved some better result this morning 7:30am, air temp 4" above pond water level reduce significantly from 23.9°C to 23.2°C. This shows some chemistry is really cooking down there...

    Full result within 3 days as told by Bro Lauts. Hence, I named her TOR-X™(pronounce Torex) as promised. He..He..\m/

    Ha ha ha, not so fast. Am not throwing in the towel yet. I just read the entire thread, I did not realise that it is an Aaron/James invention and well accepted. Hope you get to a consistent temp of 24c, you will see your koi thrive. They will bulk up, shiroji and beni will improve by leaps and bounds.

    Dato,

    Credits to Bro Aaron on the spray bar, that's where i first saw it , now it is used in many version in many ponds. Also to Bro Aznan for pushing it to sub 24C with his Tor-X. My earlier thought was 25C max due to very big variation between air temp at 33C. , now we have 23C :-D . It has disadvantages but for hobbyist with limited resources it is the way to go. At least it will bring down to a comfortable 25/26C.

    Hi Guys,

    The phrase "at the fraction of Chiller cost' is subjective.

    Bro Lauts did mentioned that bcoz he choose to use an additional saperate pump. 1 Tsurumi per 3 bar set, now adding 2nd set & still counting.

    For me, the additional cost for running TOR-X™ is actually ZERO... just fully utilized the limited source already have.

    Bcoz of that, TOR-X™ technology can be sold for FREE. HeHe...

    Just imagine... One day, most of the Koi Kichis pond water is sub 25C !!!. Previously enjoyed only by xpensive kois. Now, Most of kois can enjoy that also, being healthier, happier, bulkier & more polish. :0&

    Current Grand Champion chilled kois beware... will be lots of challenge from spray bar kois in future koi show.....KaKaKa... :-))

    After all, Benefits goes to Koi Community... Enjoy Tq

    After Bro Aron who give me a sample of his spray bar. I realized how a lot of effort to make this spray bar.

    My pond temperature drop to 28.6 C. This is because the spray bar is 50 mm and I have to use a reducer to attach it to my return pipe. As a result, the water pressure is not strong enough to push the water up to the top of the spray bar and push the water far away.

    I need to cut the length of the spray bar and also make a same type of spray bar of 30 mm size. Then I can see which of this two is more effective for my pond.

    But I am happy that the temperature goes down each day I test it. :-D

    Bro cookcpu,

    Good job on reaching 28.6C. That's more than 3° C drop from 32C from Singapore.

    A news from India, Bro Ashfaq claimed his friend pond achieved 27.7C, That's from a hot climate of 33-38C.

    A job well done Bros, for the koi community.

    Keep us posted.

    Good to see yours working well, I actually did this and managed to come from 32c to 29c in one night. My setup is currently 2 spray bars per pump. Currently only using 1 of the 3 pumps I have in my clean chamber. Will fine tune this thing to make it look cleaner visually.

    The only complain I have for this setup is the noise. If you can look past that, a worthy modification :-)

    Bro SRatha,

    Great to hear that the spray bar lower 3C in one night. It take a while to go below 28C.

    Mine just hit 27.9 C in the morning but now back up to 28.4 C.

    Now I am testing it to run 24 hrs and see how low the temperature goes to.

    The noise treat it as waterfall noise....help to calm one nerve. :)

    Bro William,
    I went back to check on the same day (today) the temperature reads 28c flat! I am truly impressed. Mine is running for 2 days and tonight will be the second night, I remembered every time I sat near my pond, I would always sweat, but now I kid you not, I need like at least a light sweater :-)

    Bro Mangkell :-)
    I guess we have to give up something to gain, so I installed a ball valve, whenever I sit next to the pond, I turn on the ball valve and the water redirects its path and straight into the pond. This drives me crazy less haha!

    Good to see more bros discovering the benefits of having a spray bar . Including benefits to the owner of cooler pond area :) . 32 to 28c is quite an achievement bro William , SRatha, any stats to share like pond size, pumping capacity , pipes size etc.
    i noted that incoming water from source can be very hot , mine 32-35C. i located my pump intake near this incoming source to help reduce water temp. Personally it is more environment friendly , we can get use/adjust for the noise and vision loss. (Y)

    thanks

    I am using one Tusurumi 15 tons per hr pump. As my pvc pipe is 30mm and the spray bar is 50mm, I pressure I get from the pump is not strong enough.

    After running the spray bar for 24 hrs, now I have a new low of 27.9 C. Maybe next round I will make 3 30 mm spray bar and using to two return pipe. Hopefully the temperature can go below 27 C.

    When I was in 2 weeks vacation, I did some DIY on this spray bar...but mine is not a normal spray bar...I adapt this from one of the koi farm in kl, modified and perfected...bro danlee, bro shukri and bro captain already see the unit....will post the picture later...the finding are as below..

    18 ton pond- morning temparature 28 deg c..when install DIY shower now at 26 deg c
    Afternoon temparature 31 deg c...when install DIY shower now maintain at 28 deg c

    What i can say, this is oly 1 set, I could install 3 set...the one set also is working only 70 % of its actual capabilities...The best part, u ave fully controll on the spray length ang the spray direction..this would eliminate problem of having your surrounding wet..

    Cost- rm 30 per unit..
    Time to build one- 20 min

    I post the picture later coz now using iPad...

My spray bar is not glued to the T so can easily adjustable 360deg. Spray length also adjustable , just cover one bar with cap la to become 2 bar only :-)) . Like your idea , pict pls (Y)

    Hi Sifu's,
    A new spray bar:
    www.koianswers.com/discussion/download/8243/Spray Bar.JPG
    Did slight modification in my fountain and convert to Bakki shower. Would put in bio ball this weekend.
    www.koianswers.com/discussion/download/8244/Bakki Shower.JPG

    After 30 hours of installation, just now did the readings @ night 8pm.
    28C v 30 C original :-D
    Would do a reading at 8 am tomorrow and update again.
    Would install 2 more small bar tomorrow as well.
    Immediate change of behavior in Koi: really active and very very hungry.
    Thanks all sifu's

    28C at night haa... Good result bro. :-D

    Guys,

    More important is, the koi like it or not?
    When you say they are more active & more hungry... Sure a good sign right?

    Pls also monitor the Pooh at 1st chamber, the new play style, their colour quality etc...
    You will notice a better result for every degree drop...

    And it's more than a chiller temperature alone, it's an environment change to them...

    I hope the community can continue to compile the pros & cons as what I start...

    Bro Lau,
    Thanks, now my temperature reads 26.5 in the morning and 26.8c about an hour ago when I was next to my pond. There are so many benefits to this system I kid you not, my water is now crystal clear, fish looks like it swims happily, no more sweating when sitting beside my pond. I was going to install a chiller as well, but I might stick with this system for awhile now. I am going to install it onto one more pump which would have 2 outlets.

    My setup is
    58 tonne pond
    with 3 mitsubishi pumps running 1 cycle per hour
    before temp at highest was 33c
    now lowest so far 26.5c
    currently only 1 pump output 2 spray bars 2.5mm drill bits.

    From 33 to 28 now 26.5C! Wow, great result.

    The variation also very small gap, 26.5 to 26.8C? Only 0.3C gap daily?
    Can U post your setup photo please?

    The drill bits, are U sure 2.5mm? 1.5mm is the optimum result for me & Bro Lauts. :-D

    Wow, a chiller & TOR-X™ installed together side by side? Very interesting indeed....


    Bros,

    Well... their battle result was declared EVEN.... BOTH WIN! :-bd
    Both can achieve 25°C, The mid of PBT & needed by nutrify bacteria.

    Bro SRatha,

    26.5 from 33C highest L-) , massive 6.5C drop (Y) . Picts pls . For your 2nd pump , suggest go for 1.5 or at least 2mm drill bits. Since your pond is similar in tonnage to mine, eagerly waiting your results of any further temp reduction.

    Bro Aznan , 0.4-0.5c temp drop in normal for a covered and big volume pond .

    Bro TK , good to hear it works for you too. Bigger capacity pump will give even better results.

    "Immediate change of behavior in Koi: really active and very very hungry".

    The spray bar not only reduces water temp but also increase Dissolve O2 by its action , similar to Bakki Shower. This is what you are seeing displayed by the kois. You have low DOC thats good , no lingering , non bursting bubble from your spray fountain action. (Y)

    Niceeee.... 27.4 haa, another 0.5 drop right?

    Yess... 3 Spray Bars is minimum with 2 rows each... For the Volume



    One reminder though,

    Those famous Tsurumi pump, if the outlet is 2" diameter. Do not reduce the pvc pipe size of 2" aka 50mm bef the "T". After yr "T" junction only use reducer to yr desired pipe size.

    This will,

    1-Care for pump reliability.
    2-More pressure delivered to each drill hole with same hp.
    3-Fully utilised yr pump potential.

    Good luck[-O<

    Bro Mangkell,

    My FATS( Fan assisted trickle shower) system is not yet finished. So far its concrete structure( with window for air to enter on both sides and the tiling is already complete while the stainless perforated trays had been precut already according to the specification. The two sequence external pump that is capable of producing a combined total of 42,000 liter output per hour without adding any heat to the water had just arrived from the States yesterday. :-D But my six Waterproof exhaust capable of producing a total output of 600 cfm that I ordered from the US has not arrived yet. The auto temperature sensor and regulator is with me already. The glass sintered ring filter media which will help in removing nitrates in the water that will be use has already been preped and culture already with good bacteria for two months now. Meanwhile, the pond now is undergoing waterproofing coating which will help also in insulating the ground heat from the water.

    Its raining lately here especially at night when temperature I think drops to 23 degrees. My 4 ton QT tank where all my kois are temporarily house are enjoying a water temperature already between 25 to 26 degrees. There I just put a simple downward shower. I am confident that I can achieve a 24 temp at night and a 25 temp in the morning once the my FATS is up and running already.

    I will post pictures and a video of the FATS after its complete and running.

    "The FATS are not yet cookIng & you already smelled 25-26! ... Scary woo... "

    haha... I think I mentioned 24 to 25C. The magic number is 75 F or 23.9 and to keep it there consistently most of the time without the use anymore of a chiller.

    In building my new pond, I already made consideration on heat reduction while improving the living condition of the kois and making it aesthetically pleasing. In my study, I figured that heat is generated in our ponds due to the following:
    1. Solar radiation( my pond setup is only partially shaded (25 percent) but most solar radiation will be in the morning.)
    2. ambient temperature which heats up the pond concrete and the ground( luckily my new pond is built under solid bedrock that is always cool)
    3. thermal transfer of heat generated by equipment( use of external water pumps will generate minimal heat transfer while forced cooling of the air pumps would drop the air temperature being pumped out.)
    4. decaying organic matter in the filters ( the action of bacteria in breaking down organic generate lots of heat. everyday flushing should take care of this. No more over feeding also helps)
    5. turnover( the faster the turnover in a shower the less heat build up and faster cooling time. mine will be 2x turnover)
    6. color of the pond. Unfortunately, I still used black color to color the pond which unfortunately is the worst color to reflect heat. I just cant accept the visual appeal of a green or blue pond.
    7. wind speed. ( artificial high velocity wind speed created by temperature regulated exhaust fan to cool the water droplets)
    8. Depth of pond.( a six feet pond should be enough)

    Good afternoon all,
    I am having huge success with this spray bar. As I stated before, I wanted to do the 2nd pump with 2 spray bars and which I did. I changed all drill holes to 1mm and the temperature in this blazing heat is now 25.7c at 3pm. This system is only a week old and a bit.
    One thing I have come to notice is with finer holes, I was able to achieve less rainfall noise aswell.

    Bro SRatha,

    25.7C at 3pm is a new evening record. Bravooo (%)

    1mm last for 1 week already without service? Yr water is less small particle than mine.

    Do update the full result later Tq :-D

    Bro Mengkell,
    Thank you for your support, the numbers are going down bit by bit, at around 5pm I was able to achieve 25.5c, early this morning I was able to achieve 25c flat, nothing else was done after completion of the 1mm holes a couple of days ago. It just seems to drop and drop. We shall see when this thing becomes stable.

    Bro SRatha,

    Congratulation are in order. =D>

    If you can maintain that 1mm setup for 1 week without brushing / servicing, the durability is good already. My 1mm need twice cleaning per week, hence go back to 1.5mm :-D

    1mm with smaller dirt particles sure got more potetial maa... :-bd

    Like your 1 pipe to 1 bar setup, same like TOR-X™, more pressure delivered. (Y)

    Bro Mangkell,
    Are you saying that yours clog up? I haven't hit one week yet, we shall see as to how big my water particles are. If it does clog up, I will move to a bigger hole, but I do hope not as to the noise will also be raised...

    Well done Bro SRatha ,

    1mm bits seems to work better. 2 pipes powered by 12T Tsurumi ? to get 25-25.5c and still going down. (Y) (Y) . Try to spray over a bigger area to disperse the water drop, it may have better result bro. thanks

    Bro Aznan
    Cleaning is easy , just spray it with garden hose will do . Mine is not glued so can easily pull out from T to clean weekly. Temp now 25.7-26.2C, bit warmer nowadays. Looks like i will need to get myself some 1mm bits too :-D :-D .

    Bro Spencer,
    Thank you :-)

    Bro Lauts,
    My pump is a mitsubishi pump, looks a lot similar to the tsunami pumps tho. I have tried to spray it larger area as much as I can without splashing outside of the pond. I am going to check now the temperature for today at 9am local time here. I suspect it should read the same.

    Bros,

    Yesterday Sun was a hot day , but my pond recorded 25.6C ( 25.4- 25.7C) at 3pm with air temp at 34-35C. Even pond side recorded 33C :-D :-D . Nothing new , have not done up the new spray bar but note it was very windy. For those not having good result suggest to consider location of spray bar in open and well aerated location. Or if necessary add a fan to improve air circulation.

    At 4pm my pond temperature is at 27.6 C. I have added a 2nd spray bar therefore it keep at this temperature.

    Before with one spray bar the temperature went up to 28.5C.

    Bro William,

    Your pond temp has a lot more potential to go down lower. To see if temp go down further, try adding a fan , at least temporary , using a house fan maybe, to increase air movement for evaporation. , I recall from pict your spray bar was situated quite secluded corner? Anywhere you can place bar to catch the air breeze?

    Bro Aznan,
    When I initially setup, Morning 8 am 26.7C and evening 8 pm at 28 C. That time is very windy and not so hot.
    After I added two more mini spray bar, the temp at peak is Morning 8 am at 27C and evening 8 pm at 28C. Have not checked during windy time.
    But yes, good ventilation does help to reduce the temp further as the water absorbs cooler air before lands on the pond water. First thought of installing a fan near the pond but HM [-X with the idea, so drop off. ;-)
  • cookcpucookcpu July 2012

    Bro TS, the place where I put the spray bar is some sort of air well. Most of the time the wind will flow to this area and then go up all the way.

    But the wind that is flowing to my house is hot wind. I think my pond is not cover so during noon time the pond water get heated up faster.

    I am thinking where to put the house fan so that the spray water will not be blown to the side of the pond.

    Hi Bro and Sis,
    Been following this quite a while, and i think this bring good result in many places. I think what bro TS do is require for all of us to test. Here what i had done before, community experiments.

    But in order to have more reliable result, we must measure the atmostphere temperature too. Different atmosphere can result in different water temp. 15minutes rain will change air temp, cloudy weather in 1hour may change water temp too.
    Regards,

    Bro SRatha,

    How is the durability of yr 1mm setup? :/ Can pass 1 week cleaning cycle or not?

    Bcoz I think yours should be OK... Simple pond setup...

    Mine got thousands of waterplants TDS to deal with... You know 60feet river...

    However, now considering to house the pump inside a box with a smaller sieve??? :/

    Hi Bro Mangkell,

    Don't ask why am staying up late so late :-) more about that tomorrow :-)
    To update on my setup, I have reached 24.5c lowest in the morning while in the daytime its about 24.8-9c. Of the 4 spray bars I have, I turn 2 off during the night and keep only 2 running to keep noise down.

    1mm setup requires no maintenance so far... I hope it stays that way...

    Sure got big project there... HeHe..

    BRAVOO... 24.5-24.9C is a new record breaking Profile Bros... =D> Clap... Clap.. Clap

    I say U, Wa cakap Lu... 1mm is really kicking...
    More sweat when U can maintain more than 1 week...
    Your TDS must be very small...

    For the sake of testing, pls consider not switch off the 2 bars for few nite... Maybe 24C is within reach... Than go back lah... [-O<

    Hi Bro Mangkell
    I live in Phnom Penh, the only KoiAnswerers that has seen my pond is Brother Melvin. Any pond visit is welcomed, just as long as I am here, gonna be a bit busy this month, and will be away for a whole month of next month :-( the only consolation is that I will be in Hawaii :-)

    Actually this thermometer- am not sure about it's accuracy. I bought one from Max Koi and it seems a tab bit lower than 25c.

    I find that different thermometers read different numbers...

    Bro Mangkell,

    Lately, since its been raining here always at night. I have recorded water temperature of 23. C for consecutive days even in my QT pond where all my kois are now. There is a noticeable difference in shine which gives the colors of gosanke a better look as compared to temperature of 26 to 28C. The kois appetite has also improved.

    Bro HDCu,

    The shines & increase of appetite for food is what we already agreed about the benefit of 24°C.

    How about the koi metabolism rate?

    I believe the koi metabolic rate is higher...

    Means, even the koi eats more, they can also absorb more, resulting in higher growth rate.
    Also more absorbs, means less waste, less bio loads, more water parameters quality... Etc...

    Can overstock more also... HeHe.. :-D

    What say U?

    Bro Mangkell,

    Its been raining here for like three continuous days and QT pond water temperature is now at 22 degrees. The beni and shine has improved even more as compared to temp at 25. I am feeding around 80 percent of my normal feed now because of the colder water and in preparation of the kois being transfer to their new home soon.

    Despite their small space for now at their QT tank all are still growing quite well. In five months, my latest acquisition of a 28cm ISA showa is now at 47cm while others have now grown from 47 to 58cm with colors intensifying. Water parameters are always good. I just checked now and nitrate is even less than 5ppm now because of the amount of filter medium being cultured in the QT pond.

    BTW, as you know increasing the dissolved oxygen to max saturation levels also increase the metabolism and growth rate of koi. I am sure your TOR-X has increase the DO aside from lowering temp but has it reached saturation level as compared to using oxygen concentrator? Hmm... something to think about also aside from temperature.

    Hello everyone,

    I followed this thread before and my hands got itchy then. But its only now that i have joined the SPRAY BAR club by buying a new sub pump of 10Tons/hour power. My 20 ton pond,8 ton filter will be at a test week run.Its been 5 days and i must say, 3 degree celsius reduction after 6 days is really tops. My 4 feet 32mm spray bar has 100 holes of 1.5mm after i have studied results by guys here.Here's my report:

    DAY 1:28-29 d c reduced to fixed 28 d
    DAY 2:27-27.6 d c , i have observed that wind direction and max of low temp occurs between 6pm-10pm. it slowly rises between 7am-4pm to a 1 d c differential
    DAY 3:26.5-27.4 d c .never had a sub 26 before and i am pleasnatly surprised. Water is clearer but kois are lethargic,maybe adjusting to temperature so i am making sure a 1 d c a day dorp differential is observed.
    DAY 4:26-27 D C - A new low of flat 26 d c at 6pm is amazing!water is absolutely cold to the touch and kois are a bit used to the cold already.theyre back to their old hungry feeding regime of 600 grams
    DAY 5:26-26.7 D C - didnt drop any further, kinda dissappointed. i bore 30 more holes on the bar to hopefuly increase drop to sub 25 maybe.i did this also to limit water spray to only 5 feet away as so much splashing on one end due to 7-8 feet water throwback.i am more pleased with the 4-5 feet water throw.

    today still at sub 26 d c,but im fine with it. i have also read about a thread regarding GO dying due to sudden spray bar temp drops,some even at 3 d c in 24 hours. That is to me too much of a drop,which at 1 d c a day or more wouldve been appropriate. Now, i am PP my pond to kill off all livened bacteria from the new cold temperature to make sure bacteria is killed off before even making any move.bacteria is more enlivened on colder water,so i bombed including filter chambers 1.5 grams per ton PP.i took off all filter media of K1 and matala mats and im half way on this 4 hour regime today. Here are my observations thus far:

    1. kois tend to react on sudden drops of more than 3 d c even on a 3-4 day span.i cant imagine such drop on a 24 hour span.mustve shocked their wits.
    2. feeding should be minimal.it took them longer to finish feed.perhaps the noise of the new spray bar had an effect on it
    3. Color of kois are more vivid.im very pleased to see more apparent gloss on kois skin at sub 26 d c.im very excited to get into the sub 25 and 24 soon.
    4. less poo on filters.my heavy feed requires me a 2 x a week spray on my 2 net sieves.im pleased to see that i can do it only once a week now.
    5. Water clarity is awesome.water is more lively,i can even see every algae at pond bottom.just amazing
    6. more do on water.some of my kois have slight gill curl,my main airpump conked out 3 omths ago and i just had a replacement this week.ive observed ease in breathing on my kois,they use to breathe hard on pond bottom.i hope the gill curl will be remedied with the new airpump and spray bar

    i am hoping that my kois will adjust to the new sub 26 climate.i may be seeing a sub 25 tomorrow or next day which would be great.thanks to all who shared about the spray bar

    bro han....looking good....cooling tower or spray bar basically works at the same method.....injecting air onto a small particles water......

    are u using also sprinkle model? or a fix pipe + hole inside the drum? i am using a 15cm dc fan on the water surface in my aquarium (volume 250ltr water). i can get 28 deg C water temp while ambient temp is 31-32 deg C. still seeking time to applying the same for my indoor pond.

    i am wondering if any hobbyst using finned aluminium/copper like radiator system. will it works better?

    hello everyone,

    Still stuck at 26 d c flat.i can only afford 1 spray bar on my set-up as my pond is cornered by walls on 3 sides.i will try boring more holes to reduce throwback to 4-5ft and see whether this will suffice.my target is a 25-26 temperature.i already have a bakki shower,so the next option would be to place my engine fan on the cover of the vortex filter. This will target a Goshiki nissai acquisition this november which i hope will retain its kuro sumi.

    eniwe its been 4 months since i first installed the diy cooling tower been working good so far
    by now theres already 3 friends with super large pond in jakarta and cibitung using the same methods

    100T pond in jakarta using 6 fans(16w) DIY CT (wandrie < sure u know who :)) can get temp lower from 30c to 26c
    160T pond in cibitung (also in indonesia u know who 2 lah hahaha) using real CT 1,25HP fan get temp lower from 30c to 25c
    100T pond in jakarta also now renovate the pond and going to install CT
