CPR Refugium Pump
I purchased a CPR Refugium off of eBay and was told it worked fine. Set it up, and the pump didn't work. I disassembled it, made sure it was clean, etc. Now it "works", but it's very weak, and can't pump water into the refugium.
I know very little about refugiums, and feel I'd need a replacement pump, but I am not sure what kind to get. Can anyone suggest a good replacement pump for me?
