That is a good skimmer, esp. after a few minor mods. I have the triple recirc model that uses 3, OTP 2000 pumps. You'll want to do a mesh wheel mod and modify the venturi to get your maximum skimmate production. One thing that I feel needs to be mentioned with the octopus pumps is that the pump outlet threaded fitting breaks really easy, so you don't want to use pipe thread tape on them (use the tube kind instead) and don't over tighten. Thankfully, if the piece breaks, you can buy a new one for about $10.
