Looks like API stress coat did go thru a formula change in 2007 and added some neutralizers but still use sodium thiosulphate


I think everyone says Seachem Prime is bestSo the api stress coat is not what I want to use? What Is the best to use for big water changes
I use straight sodium thio mix to treat my chloramine treated tap water, although the thio does not effect ammonia, it does break the chlorine bond, and neutralize the chlorine.
Here is an aliquot of straight tap before sodium thio treatment.
Here is an aliquot from the same sample, but after neutralization with sodium thio![]()
this is highly inaccurate.I only read a little into this. You dont need to worry about water changing if you did 20-25 percent every 3 - 4 weeks. You check your parameters and they are fine then you have nothing to worry about. Fish is probably growing just fine. Every fish will vary.
