I have a 29 gal tank with 2 round body red cap orandas, each is about 4 inches max from "stem to stern". The filter is a Top Fin 30 with charcoal medium that cycles 150 gal/hour. All my water parms are good, except I
am still tring to get the ammonia level down to zero...usually it is about .25
I was looking at an Aqua Clear 300...is this too much?
