Aquarium Advice Addict
I just bought a used 84 gallon tank for $300. It has undergravel filters, two HOB filters, rocks, plastic plants, castles...etc.. Do I still need to cycle the tank or will the bacteria that is presently in the tank be enough to start? I know I will have to test for Nitrite, Nitrate and amonia. But if the levels are right can I assume that I can introduce fish or should I induce a cycle? Any help would be appreciated.
