Can you tell us more about your Abyzz A200 return pump? Do you have an ATO if the return pump is returning water at different rates?
After trying various pump ranging from Eheim, Aquabee, Reef Octopus...etc, none even close to abyzz. It is extremely silent. Highly recommended if you have additional budget. I did not have issue with ATO because the time interval for wave is too short for ATO to kick in. I can see the indicator light blinking. Fyi, i m using tunze osmolator.
