GFO in a HOB filter?

[Bnortz]

So I have a Tetra Whisper HOB filter on my 60 g and currently all there is in it is what came with it. (I think carbon bags and some other media) I can't fit a sump to run any reactors but was wondering if it was possible to run GFO in this filter. If so, how would I go about doing this? Let me know what you all think.

Thanks

You can put it in a filter bag but it wont be as effective as if it was in a reactor. make sure the flow kind of suspends the GFO and it doesnt just sit there like a rock. and follow the instructions on the box or what ever it comes in too much GFO and your corals WILL bleach

are there any HOB reactors?

The reactor by two little fishes they call it a phosban reactor can be made to HOB with a kit the sell.
