Ive recently upgraded my ac return pump to a dc pump and the noise difference is literally night and day. I could not even tell that my return pump is on if it wasnt for the water movement the return pipe gives off. Im wondering if the skimmer would be a similar result its by far the loudest thing in the tank , with it off the only thing i hear is the sound of water surface breaking, its not the loudest thing but definitely hear the hum. Does anyone have experience moving between a ac skimmer and a dc skimmer ? im not to sure if the change in volume would be as drastic since air is added into the mix with a skimmer but without the vibration the skimmer is barely audible. The skimmer i have is a great white gw10 and it works really well, it has rubber feet on the pump and skimmer body so idk what else i could do to reduce vibration noise on it. which is why im considering moving over to the same skimmer but dc version. Any input or advice is welcome.
