- Reef Octopus Media Filter 3.5" Chamber
Reef Octopus Media Filter MF-1000 has two cone strainers on each end to prevent large course media from being passed through and allows for the dispersed contact around the media for more efficient chemical filtration.
Adaptable input and output – PVC or flexible hose. Equipped with inlet precision control flow valve.Diameter: 3.5"

Look elsewhere By Carson on 9/23/2017Carson wouldn't recommend this product to a friendUnit I got leaks from a ring of plastic thats supposed to be fussed together near the top threads. I had also asked a BRS rep if this unit has strainers capable of running ROX 0.8. The carbon ended up being to small and back flowed into the reactor.
disappointed By chrisd on 6/17/2015chrisd wouldn't recommend this product to a friendAfter running this reactor for a couple months now I've come to the conclusion that this reactor is not all that great.
A few design problems with this reactor.
1. The inlet should be horizontal rather than vertical. This makes for having to keep the pump farther from the reactor due to having to use more hose and could pose a problem in a small or crowded sump.
2. The push style barb fitting if not tight can and will come out. I recently had the outlet fitting come loose and sprayed water all over the inside of my stand.
3. The quick disconnect on the outlet should also be on the inlet. This would make for a much easier time at removing the reactor for cleaning and media change. The other thing is the ball valve. I ended up running it wide open and used a two little fishes valve placed after the ball valve, this made fine tuning the reactor much easier.
4. The reactor lid should be the same size as the reactor body. The smaller opening makes cleaning out the media a mess. The other problem is the bottom of the reactor. There is no way to access the media that falls through the screen so you have to run water through the top and try to get the media to come out the inlet. Not a big deal but with trying to get all of the media out of the body as well, I really don't like having this go down my drain.
For the money BRS reactors are a better choice.
Well constructed and easy to set up By Kane on 4/2/2015Kane would recommend this product to a friendVery well made. No issues setting this up. I bought one for activated carbon and one for GFO and both are running well. Would be nice if the base plate could be anchored to whatever it sits on since it is top heavy until it is filled with water.
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.

The pump size for that reactor will heavily depend on what media you plan on running in the reactor and how much. For GFO you will probably want a pump that can push around 500-600 gph where with carbon you will probably only need around 300 gph. We would always suggest getting a pump that will flow a little more than you may need, and then using a ball valve, or gate valve restrict the flow to where you need it. You may want to look into the Waveline DC pumps since their flow rate is controllable, and the Waveline DC2500HP pump makes a great little reactor pump.
It wouldn't be any issue at all to run GFO in the Octopus media reactor for removing phosphates.
