Currently shopping for a new canister filter, I currently have 2 fluval 306 and 1 fluval 406 as far as canisters go. I have liked the fluvals, both the HOB and Canisters but thought I would try a different setup. I have heard a lot of people running the Eheim canisters but don't know much about it. The next filters will be on a 75 gallon grow put tank for some Oscars ad then be moved to a 300 gallon Oscar tank in the future and the other ones will be on a 75 gallon JD tank. So any ideas on setups or something to try would be appreciated! Hopefully this will help others in the same boat. Thanks in advance, I did seach but didn't see anything or don't get the search function.
