tolstoy21 Posted June 3, 2021 Share Posted June 3, 2021 I'm looking to build a DIY undergravel filter for a 30 gallon aquarium. Do these require a specific amount of flow to operate efficiently, or can one be operated with a gentle amount of flow provided by an air stone? Would a small powerhead be a more preferable option instead of an air stone? I'm looking to set this up in a betta tank. Link to comment Share on other sites More sharing options...
