I have a 75 gallon tank I started a couple months ago, and just use a hob filter rated for 75 gallons. After awhile my Grandpa became very interested in my tank and decided to start his own aquarist journey and he picked up a 55 gallon for himself. I helped him with getting all the starting things for his tank and which LFS's were the best to go to, but when talking about filters he said he'd done some research on canister filters, and that they're supposedly much better at the job than HOB's. I guess my question here is, should I consider buying a canister filter? it seems as if my hob is doin the job just fine, but I guess I really don't know what I'm missin out on when it comes to canisters. Lemme know!
