Upgraded our Aquariums filter today from a little submerged 15Gallon filter to our new 40Gallon canister filter.
It was a huge pain in the ass to clean the filter media since all the crap just released back into the tank, with this new one the media is never in the tank so there's no risk of it happening again, Plus it'll be good for when we upgrade tanks to a 40+ gallon.
The only down side: $159.99
