I have a 55gal tank with 6 small goldies. 2 weeks ago, I had to completely drain my tank as I had an ammonia problem. I filled it back up and added the fish, assuming the cycle had started. Iím now on day 15 and no nitrites have shown up (0ppm) .
My ammonia is 0.5ppm - 1ppm (usually closer to 0.5ppm) after water changes (which I do a 25% everyday) and after every change I add QuickStart and aquarium salt.
Last time I cycled my tank I had nitrites by day 10.
Another thing, may be important, I cleaned out my filter a couple days ago (it was about 2 weeks since I cleaned it before then) and it was covered with browny/orangey sludge, like it hadnít been cleaned for a while.
Does that have something to do with my problem? Any ideas? Thanks
