Hi all, starting up my 3rd nano tank and it’s been a few years. Got another bio32 and some rock from this nice guy you all may know (erics210) and it’s been a few weeks now. Ammonia seems to be stuck for about a week now ~4.00ppm (dark aqua green) with no drop in ammonia. Minimal nitrites and have nitrates. Added a purple bottle of one and only and some new Caribbean Bahamas oolite sand from start with the rock. Thoughts here, water change, let it keep cycling? Lights only on for the pic. Ty for any advice in advance.
