Have a 10 gallon with between 2-4 ammonia. I have been changing about 10% of the water every other day (after removing 50% about a week ago)and the level does not seem to be moving. The only fish in the tank are 2 long finned zebra danios and 2 glass catfish. Had a pleco but we removed him yesterday. Do I need to change more water? I have been using Amquel and the fish seem to be fine but I do not want them to get sick. Any suggestions?
I have been vacuuming the substrate when I change the water. The pleco was removed yesterday and ammonia was still high as of this morning. I have a Whisper filter. Should the water be changed with out cleaning? The pleco was so messy that even cleaning the substrate every other day there was a lot that was being pulled out.
