well...
according to wyldfya the bioload the filtration absorbs is mush more important than how much water is filtered, and i tend to beleive that theory, all canisters are different and the amount of turnover/bio filtration is all dependent on the tank size you have...
edit- 75 gal i see
i beleive 10x-15x turnover with alot of strong media's is adequate.

For a 75 gallon tank, I'd personally aim for 300-400 GPH from an eheim, or 500-600 from any other canister. The most important thing is that the water has time to contact the bio-bacteria. If the water is going too fast, the amount of ammonia that is being converted is less.
IMO, i always thought that 6x turnover for canisters. Thats what i have read. But that doesnt seem like much.
Rather than theorizing, let's look at a real-life example. I have two XP3s filtering a well-stocked 150 gallon Dat tank. Each XP3 is rated at 350 gph which translates into approx. 200 gph (max) per filter when filled with media. Collectively, I am moving approx. 400 gph and my water quality is excellent. On this tank, 400 gph is less than a turnover of 3x per hour, BUT....in 24 hours, the water is filtered approx. 64x.
