Aquarium Advice Regular
About 2 weeks ago I changed the layout of my tank. Removed all rock and fake plants. And replace with all new rocks and plants. Looks great. Fish have more open space to swim. (55 gallon). A day or so later I checked the water (api liquid) and my nitrites were sky high. 4ppm. I did a water change. Dosed with prime and stability. Its been 2 weeks now and still the same. No nitrates. No ammonia. Would changing the rock out kill off my bacteria. Was all the bacteria on the rock.the tank was fully cycled up and running 8 months . Fishless cycle added all 12 fish at once. Never had a problem with nitrites. Never had an issue. 12 cichlids. Around 3 in. Weekly water changes for nitrates usually when I got to 40 ppm. I even left 4 small pieces of rock from the last set (texas holly ph buffer.) I have sand substrate. Black Tahitian moon. I have 3 canister filters on tank. Eheim ecco.80(bio media) fluval 306(phosguard and mech) and marineland 350.(carbon). My water is crystal clear. Looks like the fish are just floating on air. Did I screw up changing everything around. Hope to get the cycle going again. Dosing with prime and 50% water changes every other day. Trying not to lose any fish. Seems like their good. I think I stress them a little with all the water changes. Also using well water. Nothing out of the ordinary. Same way for 8 months now. Any help would be appreciated.
