Getting back into the hobby so I had my tank set up fishless with liquid ammonia from brightwell and microbacter 7. There's 1lb of lr in a 15g tank with 20lb of live oolite. The tank was set up one week ago and I saw ammonia rise and fall, nitrite rise and fall, nitrate rise, then dissappear? My old cycle, nitrate rose then sat around 10 to 20ppm but now its 0. I got it tested at my lfs and they said 0 too so im wondering if my tank might have TOO good of filtration?
