whenever your nitrites or amm get above .25ppm it's wc time, could be once or twice a day, prime is a water conditioner first and for most, it does just happen to detox the bad stuff but that does not mean it should be a substitute for a good ol fashion water change, as far as amount? Say your at .5 ppm amm, a 50% wc will bring you down to .25ppm, another 50% will bring you down to .125 ppm. 50% is about as much as you'd want to change at once!I'm in the midst of a fish in cycle and using prime to help detoxify the water for my fish. My question is at 0.5 ammonia should I dose with prime or water change? If I need to change the water, how much should I replace?
Ok, thanks for the info. I'm determined to keep my little guys as healthy as possible through this. Gonna test water and act accordingly. By the way what's your take on the bottled bacteria stuff? They can't all be useless can they?
