BioCube extra filtration refugium and canister

[whisenhunt]

recently picked up a nice canister filter for cheap couldn't pass it up , Now my question is can I turn the back of my biocube into a large refugium taking out all the media just running rubble rock or mud and a lot of chato and other moss. Then running all my media in my canister filter? I know I need to stay up on changing and cleaning my canister out to make it not a nitrate magnate 
it is a 32 gallon led biocube set up with coral and fish
thanks so much for your input

  I would say yes with a couple of exceptions or watch outs, one -    you would need a small LED for the Chaeto - you would still need to clean the Fug now and then but having the filter media out of the back chamber may not be a bad thing, easier to clean and of course you need to pump water out to the canister. Keep us posted on progress!!!

what kind of light does chaeto need to grow will just a cheap non fish led work ?
