Turnover here is the maker’s figure for a clean filter. Real flow drops as the media fills and the water has further to climb, so a filter near the bottom of that column has the least to spare. Slow swimmers such as bettas want gentle water: choose one with a flow control, or see how to read flow ratings.
Rated for it, but more than it needs
These cover 75 gallons on paper, but their ratings run past 3 times that: more flow, a bigger body and more cost than the tank needs.

- Fluval FX6: Rated up to 400 gal: it covers 75 gallons, but it is built for tanks over 3 times that size.

Before you choose
A rating covers the water, not the space: measure behind the tank for a hang-on-back filter, and the cabinet height for a canister. Compare the filter types, or plan the whole tank’s equipment.
