Hi, i did a fishy cycle with my tank, didnt know any better, know I do. Anyway, ammonia has been long gone (for about a month, tank is 2 months) but nitrite and nitrate are way up. I also believe I had a heavy bioload. Recently I have given away 4 fish due to their projected size, so well see if this helps. I was wondering if my tap water might be the culprit, even though my first 3 weeks or so was free of both. (tap water wouldnt make sense then). http://www.sandiego.gov/water/quality/pdf/quarpt05.pdf Here is the link to my water report, I dont know how to make out the readings(pg. 8) Any, ideas, suggestions or advice on my problem is appreciated.
