carbon/phos react?

I havent, but I have seen others use it, I think PaulPSU does. Its just 2 10" filter housings in series. I use precision marine reactors.

You want to tumble GFO but not regular carbon, use a dense lignite or ROX carbon.
 
Yeah...I am debating which to get. I want to run both materials. I have seen people do half and half in their phosban reactor as well. Also, I was looking at the Seachem Seagel which has both mixed together and can be run in one reactor. I am assuming separate would be better for maintenance purposes and life cycles of medias. Which brings me back to the original question.
 
I have three of the GEO small reactors for my tank. I like them a lot. They are easy to maintain and you can hard pipe to them too. I have a individual mag 5 running each one, that way they can be controlled seperately with the AC 3.

Keep them separate.

Yes - keep them separate. Your GFO will need changed far less often than your carbon so you will save $ in the long run. I run two TLF reactors in line powered off the same pump - first carbon then GFO. They pull water after it passes through my fuge / chaeto. Seems to work well for me
 
I have the (2) of the TLF reactors and run GFO and carbon separate. I was thinking of switching to those from Bulkreefsupply. I have read a lot of good review about them. The TLF ones I have work and are ok, but are made cheap. The only thing that I don't like about running the two reactors in a series is that GFO and carbon generally require different flow rates. I had mine run in a series on one pump with my carbon flowing into my GFO reactor but changed it and built a manifold and each has it's own ball valve now. Like buck50bmg said you want the GFO material to just tumble in the reactor. From everything I have been reading, there is no magic number on when to switch out the GFO since it depends on which one you use and the amount of phosphates in your tank. Most people change monthly on both to be safe. I have also read where if you have high phosphates that the GFO could become exhausted within a week and actually start leaching phosphates back into the water.
