I am setting up a 55gallon brackish tank and I want to go with a canister filter but I don't want to get the wrong thing I know that mfk recommends the rena xp3 but is that a good filter for my 55 gallon setup. I also dont want to spend crazy money I found the xp3 for $150 so thats doable. also I would like easy maintenance being that this would be the 4th tank in the house. Please any info would be great
