The filter with it is a minmum amount of filtration. I would pick up a bigger filter. Either a bigger HOB
or a canister. Then you can either run the filter that came with it as extra or save it for a smaller tank. One suggestion would be to place the HOB
it came with on one saide and then get an Aquaclear 300 for the other side. 2 HOB
's would give great filtration plus will assure that if one breaks then you won't be in too much trouble.
