Welcome. I have 3 tanks, 1 cycled & the other 2 in the process of fish in cycling. Patience & consistency seem to be key. If I'm not mistaken the PWC
% depends on your levels, the higher the ammonia level for instance would mean a bigger water change & how consistent the reading is would determine how often. Best of luck, I'm finding the best advice comes from those who have been through the experience which is AA.
