I have been looking into canisters for my 55 gallon tank. I saw that some of them (aquatop) have UV filters. Should I want this? I want to find a good canister that will be no more than $150 (preferably less) for my 55. I have been doing independent research but I am getting so confused. All I really know is that I probably want a spray bar because the 55 is most likely going to be a betta sorority and I want to reduce the current. I also know that I would rather not use and HOB in conjunction with the canister. Any advice would be appreciated!
