if its either of those, no catfish or pleco can help you.
those two are often caused by high levels of phosphates in the tank water.

you can also have your water tested for that, which I would recommend before you decide that its phosphates.
It usually is (most tap water has pretty high phosphates) but nitrites/nitrates and bad lighting will help contribute to it as well.
