HotTunaCartel Posted December 4, 2021 Share Posted December 4, 2021 I'm using the ACO powerhead (love it!) to spread co2 throughout the tank. My question is if anyone has used a controller for it to slow down the speed? I have a speed controller in the garage that is old but still works. Wasn't sure if I should get one specifically for wavemakers of if the one I own would work. My other option was to use a higher ppi sponge filter for it but I don't want to physically restrict the motor. Any help would be great Thanks Link to comment Share on other sites More sharing options...
