some of you know my plight with the set up of my new tank. here is the bottom line. my nitrites are sky high and have been for about 3 weeks. nothing i do has brought them down. amonia and nitrates are good. i have done two doses of bio-spira and dose with stability every day. i don't know what to do. i finally did a gravel cleaning and got some of the waste out of there but i don't know what else to do! i have a biowheel filter and bio media in my tank. any suggestions? the tank is about 1 1/2 months old now. i know i'm "in the middle of a cycle" but should the nitrite phase really be taking this long?!?
