But none of those things is happening. So, it seems to me, there's something wrong with the pump -- either it's malfunctioning or it's poorly designed.
I wish I could answer your questions re the pump, but this entire system was custom made. I looked at the pump itself. It says it's 115 volts, but there's nothing else that would serve to identify it (just some model #'s). I believe it's an air-cooled pump, because when I put my hand beside it, there's cool air coming from it.
I went out today and bought some cooling fans, as per your suggestion. I'll have to find a way to mount them. I don't want to use them until they're securely fastened to something, since if they were to accidentally fall in the water, they'd presumaby electrocute my poor clownfish!
The cooling fans have 4 holes, I just screwed mine to the canopy lid. Your going to have ask the fish guy what pump it is, because if you are going to replace it you'll have to match its output if its your sump return. But, if you feel air running across the body of the pump, it does have an external fan onthe back of it. I've used them before, mine was a Gen-X, it did get hot, but mine had a plastic head where the water flowed through, never had to worry about heat transfer fromthe body.
