I think I have an Atman ph3000 pump somewhere...Didn't run it for long, so I don't know how reliable it is. You know how Chinese stuff is...haha
EDIT: Nevermind. It was 400-600L not gallons.
EDIT2: I do have an old Nac6 skimmer with upgraded SP2000 pump, but I had some issues with it. If you wanna try it out before you buy it to make sure it works right, let me know, and you can pay me later. $80 sound good?
