I was under the impression that the canister filter alone wouldn't be enough for a 75 gallon. Good to know. Thanks
Filtration depends solely on the fish. A lot of the misunderstanding over filters occurs because some aquarists don't realize that different fish have different needs when it comes to filtration. Those who maintain large fish like the big cichlids need good filtration and water movement. Those of us with smaller fish in planted aquaria want minimal water movement and don't need much "filtration" because the plants do it and the fish make less of an effect on the biology, assuming everything is in balance.

Forest fish occur in slow or still waters, and do not appreciate water flows that cause them to "fight" against current, and this causes stress which means health issues; there are some obvious exceptions, this is a generality. Also plants need somewhat specific water flow to thrive, as I explain in part 3 of the article at the head of the aquarium plants section if you're interested in the reasons.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

They make some pretty awesome large sponge filters which are great for angels and discus. I have one which filters an immense amount of stuff from the water with very little current resulting.
