This product did not suit me. After 6 weeks without fish in the tank, the water is still not circulating. Used the whole bottle with stability 500. Finally added a few goldfish and after 2 weeks it finally worked. The aquarium is always tested for deadly nitrite and almost no ammonia. I think only one species of bacteria lived there and not the one that metabolized nitrites.
