Hi Biggen, So the heater is in your sump? Then the sump must have enough water to cover the minimum water line of the heater (unless it's fully submersible and is attached horizontally?) and the pump must run constantly to pump up the heated water and pull the cooler water in the tank down to the sump. I know the heater doesn't run constantly, but the sump pump needs to? The sump also must be deep enough to hold the carbon filter. Is it a small HOB
freshwater type filter that you put carbon in? I don't run carbon in my FW
unless I put meds in the tank. Should SW
systems use carbon all the time? Can you give me a general ratio of tank capacity to sump capacity?
Sorry for all the newbie questions! I hope you're not sick of answering them!
I will rent the "Nemo" DVD this weekend, and watch it on our home theater setup! (that's why I can't put a tank in that room; may be too loud for the fish, especially the way my husband likes to crank up the surround sound sometimes!)
