at what pH is ammonia less toxic???

[Bubble_Boy]

i heard that a low pH means less toxic ammonia.

can someone please tell me what pH level, the ammonia becomes less toxic.

Ammonia toxicity reduces 10-fold with every unit of pH reduction, but I'd say when you get pH 6.5 or under ammonia is not a problem. However you have to stay at that pH consistently. There are some interesting articles in The Krib about this.
