Rowa phos and carbon

You could use the reactor for the rowa, and then a sock/bag for the carbon and place it in your sump.

I have heard this said many times, and maybe it is ideal to have them separate. But I can say, too, that it definitely works just fine to have both on the same flow.

I use a DIY reactor (using three old RO canisters), with a prefilter in the 1st, carbon in the 2nd, and HC GFO in the 3rd. I have a line T'ed off my return pump and control the flow with a ball valve. I have it set to have the GFO just at the edge of a tumble, while the carbon does not tumble.

Here is a link and pic of my set-up. Works great for me, and very quick and easy to change the media. I had to also modify the internal refillable media cartridges to remove their fine filters.
