Ive had the octopus rps-1000 its fragile,loud, and it will not restart itself after a power outage.You have to blow into the venturi to get it started agin.I have the euroreef rc80 now and its very sensitive.It doesnt have a drain valve on the skimmer cup, which is a very nice feature to have.Other than that it works great!IMO..
