FYI, I was at the PetSmart in Arvada (near 76 off wads) and they had laguna powerflo 700 filters on sale for like 120 or 130 (normally 200). there's no biological stage and you still need a pump, but it has an in-line UV filter....just thought I'd put that out there. I figured it was just a canister, which is why I was going to post this and I found out that it has no pump or bio, but I still decided to post it.
I went all the way down there Monday and there was a sign on the door that said closed today due to an emergency
