Reef Octopus MF-1000 review By Deekmann on 2/11/2013Deekmann would recommend this product to a friendI recently purchased this MF-1000 as it is working very well. It has not clogged and you are able to adjust the flow with precision. I am running with a Maxi-Jet 600 and that has plenty of power. This unit replaced my BRS unit because it kept getting clogged. I am now running carbon in my BRS unit with the two sponges. It's expensive, but I would recommend this to anyone who wants to run GFO.
