I meant to keep your water clear, etc. not to cycle the tank.
From what it sounds like, a lot of you say it is useless, but the poll suggests otherwise Anyway, I've decided not to buy any more Stress Zyme.
I think you needed to be wayyyy more specific with your poll. I would hazard a guess that if you had stated the above in your original question, you would have much more negative results... I've never heard of it being useful for that purpose in fact... The only thing I add regularly is a dechlorination agent, when I change water.
