I have the reef octopus bh100. Its an awesome skimmer. At first i had some trouble with it, but it was mostly my fault because i didnt put the air-hose on it to create the bubbles that trap the proteins. But after that everything worked fine. 5 Minutes ago i just cleaned out the collection cup. It was filled with murky water and disgusting thick crud lol. Its working A OK and i would recommend it to anyone who wants a
HOB skimmer.
P.S. I thought it broke once, but the only thing that was broken was my brain xD
