Please help. I'm new to fish keeping. I got a new 55 gal tank. Put water in 2 weeks ago, then added filter for one day before getting fish. I used TopFin declorinator and Bacterial Supplement before adding the fish. I have done 5-10 gal water changes at least two times per week. I have 4 fish. A yellow lab, pleco, acie and one "assorted" cichlid. After reading some threads on cycling a tank, it looks like I should stop using the bacterial supplement because it may prevent the tank from cycling properly. I've tested my water every couple of days and all levels have been at zero, with the exception of two days ago with the ammonia "appeard" to be at .25. I am truly confused about how I should proceed. Should I stop using the supplement and just let the tank cycle on it's own? Please help with any feedback. thanks.
