If you're feeling fancy, you could also try a canister filter with a spray bar. It's overkill for a 10-gallon, but the flow is super gentle if set up right. Just saying.

I've always preferred sponge filters for their simplicity. They're reliable and don't require much upkeep. Plus, they're safe for bettas with long fins.
