Bests & Worsts Reviews from Amazon

Received this filter today very happy and excited to set up. The set up was a breeze and I got it to run pretty quick.with that said it didn't take long for the "bio-wheel" to start acting up first one of them stopped turning so I checked and made sure set up was properly installed. Everything checked out. Back in business, sure enough the next one stops spinning I too check that one everything was OK.. So both start working...AND guess what now they both stopped spinning... Those wheels are a Gimmick.... Either I received defective bio wheels or this entire thing doesn't work...
