Okay, thanks to Cliff, I have the UV sterilizer lined up, but now need a canister filter to power the sterilizer for my sumpless 120g

Does not need media of any type, but must be in good working condition so there are no floods

Will need it for a few weeks to try to get rid of ich from the 120g.
Please PM me if you have a useable canister kicking around that you wouldn't mind parting with for awhile. TIA
