    Guys,

    Any one who use sodium thiosulphate in their pond. I have diluted 10g of crystal ST into 100ml of water and from my test, 0.5ml of the mixed solution is able to dechorinate 10l of tap water. I would like to know what is the right dosage for those who use ST on their pond.

    Cheers.

    My dealer also gave a very approximate measurement - by showing hand gesture only, but what I gather and practice is about a tablespoon per ton of water I changed. So far so good... I didn't actually measure the chlorine level though... :-ss

    Bro Mike,

    I did a quick internet research. 1 tablespoon is approximately 12.5 gm of granulated sugar (what a useful fact, huh!) I guess that this is closest to sodium thiosulphate crystals. 1 tablespoon is 3 teaspoons. So I conclude that for a ton of water you need approx. 1 teaspoon.

    Disclaimer: I take no responsibility if the above guideline is not correct and becomes harmful to you koi! :-S
