You'd probably want a bigger AquaClear. The one on my 15 gallon is rated for 50 gallons, and even set on max setting it's not too much for my fish. For excellent water quality, go with two filters rated for a 50 gallon tank. Then you have filtration for a 100g tank, which will lead to better water quality.
With two filters rated for 30g tanks you could probably get away with a regular tank, but for higher quality you'll need more powerful filters.
