I gone through some of your previous discussion about your pond and also the way you groom the koi, it is very useful info and thanks for sharing.
As Im going to build my new pond soon, i have a question to check with you. For the bottom drain in the filter chamber which connect to the dry chamber, are you using 1 pipe to connect the 4 or 5 chambers or each bottom drain will have individual pipe to connect to the dry chamber. My contractor propose me to use 1 pipe connect all to the dry chamber. Any pro and cons to do that?
Hope you doing fine. I saw your post regarding your new pond, congrats. Im actually planning a pond as well. Can i talk to you so that i can learn more or to understand more about the pond structure? my contact is 0123153368.
