I feel like 2 fx5's are not enough bio, they are loaded with pot scrubbers, but is this enough for this size tank? i have only ran sump in the past and my water is so clear. BUt now with 2-fx5's it seems a little cloudy... any suggestions?
Can you add some more filters? From your pictures it looks like the tank is not drilled to be set up with a sump? Could you also move some of the non-ray fish to another tank for awhile?
