When I switched to the API Filstar XL on my 55g, I left out the HOB
that had been running. It makes it look a lot cleaner without it being there, has absolutely minimal noise that way, and it's one less piece of equipment to maintain. A canister shouldn't really have a problem, but is definitely worth keeping the HOB
on hand to throw in if needed. Just my two cents. Have fun when you step up to a canister - it's well worth it!
