| || | Nitrogen Cycle Question
Hi this is my first post so hopefully I'm not asking something that's already been answered.
I have been cycling a 55 gal tank for a little over a month now and everything seemed to be going ok, I am using 8 cherry barbs and 1 small plant. The ammonia went up, then came down as the nitrite went up. Then both (nitrite and ammonia) started coming down together until they were both at .25ppm. Then yesterday when I checked the levels the ammonia was .2 and the nitrite was at 0. So I checked the nitrate and it was only 1 or 2ppm. I don't know if I somehow killed the bacteria or what's going on, if the nitrite is 0 shouldn't the nitrate be up higher than 2? And shouldn't the ammonia be at zero if the nitrite is?
Just wondering if anyone has experienced this or has ideas as to what's going on, thanks.
