My 125 gal planted tank is being filtered by an eheim 2217 and a fluval 404. I've the outflows positioned for almost no surface movement. WHat is the best way to deal with the "pond scum" which collects on the surface.
Secondly, I lost a 5 inch brisltenose pleco last night. Since he was the latgest fish in the tank I'm guessing he suffocated due to the O2 being depleted. Any way to confirm this, and if so avoid it in the future?
