Canister size

[Broncovin]

Ok I am really undecided. 30 gallon tank which Fluval canister should I go with for optimal filtration?
406 - 100 gal
306 - 70 gal
206 - 45 gal
106 - 25 gal
Please help me make the best decision

I wouldn't go any smaller than the 306.I always get as big as I can afford at the time.fluvals aren't bas I prefer Eheims.

You can never have too much filtration - but from a cost/benefit perspective I think the 306 is the way to go. I used to have a 30 gal reef tank with a 304 (old model) and it was plenty of filtration.

Filters always state a lower rate

The more turnover the better
