can someone help recommend which canister from sunsun I should use for a 55 gallon planted with lots of small fish? Planing to upgrade to a 90gallon planted in the future so I would like to still be able to use it. Will the 404b be too much flow?
Just get two 302's. your can put them on the 55 and valve them down for a slower flow. and then when you upgrad to the 90 you will have the filtration you need.
