Canister filter as GFO?

[ethuman]

I have a magnum 350 canister filter sitting around and wondering if I can just use it as a gfo if I took out the fiber and just put phos media in the center?
Thanks

Obviously, a reactor would be better, but I can't think of a reason that won't work. I ran a canister full of carbon for years on my 60 cube.

Well, ok, I did change it from time to time:lolspin:

My concern would be too much flow for the gfo. If it tumbles too much it will grind itself to powder. Back on my 75 I used a reactor so I could dial it in so it just moved a tiny amount. Would be hard to dial in on the filter, probably. Would be great for carbon though.

If I had valves on the intake and return lines I should be able to regulate the flow/tumble right?

Should be able too

I wouldn't even try to get it to tumble. In a canister you won't be able to see it in any case. Just put it in a mesh bag (I have a number of old chemipure bags I use) and put it in the canister between sponges or whatever and let it go to town.
