I recently purchased an air pump and it makes a lot of bubbles and creates a current in the tank that stresses out my betta. I keep a glass orb as a baffle near filter outlet, but the current from the air pump pushes it away and that makes the current worse. So, I plan on keeping it off. I know betta are labyrinth fish so air pump should not be necessary. I have plants but no other fish. Is there any benefit to me ever turning the pump on? Should I return this product? It isn't even "super quiet" like it claims.
