Am having a bit of trouble getting the ammonia level down to 0 in my big tank. Have tried water changes, introducing bacteria cultures, etc - been running for 5 weeks on 2 filters and still ammonia is at0.8. Any advice?
Do you hav fish in there. How many how large is the tank What are your levels for nitrite and nitrate? Is the tank cycling? need the answers so we can give you the best advice possible.
