Hi all, really desperate for some help at the mo for my new fluval fresh 129L.
I began fishless cycling (using household ammonia) 5 weeks ago now. Was dosing up to the 3ppm level consistenly. The tank is filtered by a fluval 206, very fine black gravel, lots of plastic plants, a thin piece of bogwood, and stacked rock (do not know exact type..most likely to be sandstone). After the first week I was getting a steady level of ammonia, no nitrite or nitrate. By week 3 nitrite had began to rise, ammonia was falling and was quickly followed by high levels of nitrate. The 3ppm of ammonia was clearing within 24 hrs, although nitrite and nitrate remained high, so did a big 80% water change. Reduced my nitrate slightly but still had massive level of nitrite (off the chart). I've since done 3 water changes (spaced out over 2 weeks) two 30% and one 50%. All that happens is a small reduction in my nitrate. I'm still adding ammonia steadily (although reducing the level to 2ppm) as when I stopped it didnt seem to help anything.
I don't know where to go from here, my ammonia is dissappearing within 24 hrs but there is just no lowering my nitrite or nitrate
Is there something that i'm doing wrong? Or is it possible that rock can bring extreme levels of nitrite?? I'd appreciate any help
