Hello. We currently have a 75g with an Aqueon QuietFlo 75 HOB filter. We are considering ADDING a canister filter to the setup since we also have plants in the tank and want to ensure we have adequate filtration. Not knowing a lot about canister filters, any tips on which brands/sizes, etc would be appropriate for our setup? We have a wet/dry on our other tank, but I'm not familiar with the working mechanisms of canisters. does anything special have to be done to the tank to add one? Note: we aren't currently overstocked in our tank - just being proactive.
