in my 40g reef tank there are a lot of sediments and sand bits that are kept aloft by the water current, as well as other little things. I have heard that a canister filter can be bad for a reef tank, but why? as long as you turn it off while your feeding, then everything should be fine.
mechanical filtration is the main thing that I'm getting at, to remove particles from the water colume. but, carbon can help with chemical wars and what's so bad about some extra surface area with bioballs?

a lot of people in my area use the marineland hot magnum. They generally use it once every 2 weeks for mechanical and chemical(carbon). They leave it on for a couple of days then take them off and dry out the floss and replenish the carbon for next time.

Bit late, but Ill chime in anyway.
The key to using a canister on a reef tank is regular cleaning and replacement of media. I use one on my 90g, and I run Rowaphos and carbon in it. I replace the media regularly and carefully rinse out the inside of the canister. Note that rinsing out a canister filter usually drops the water level significantly-you will want to have replacement water mixed and ready.
