Has anyone found a way to stop the buzzing sound? When it comes on it does the click, then keeps a loud buzzing sound.

Hi, There may be impurities in the solenoid valve, you can open the solenoid valve to see whether there are impurities in the pipe, and then remove the impurities, this problem will be solved. If you have any problem in use, you can also contact us through Amazon order email, we will always be here for you. Lucy DaToo Aquarium

How do I exchange a faulty unit under warranty. Thanks

I'm not sure,as my was faulty out of the box. I returned it from the start and purchased the Fzone regulator and have been very happy with it.

what does it mean if the water drains (not leaks) out of the bubble counter? Do I have it set up wrong?

Hi, Maybe the bubble counter is loose there, you can try tightening it. If you have any problem in use, you can also contact us through Amazon order email, we will always be here for you. Lucy DaToo Aquarium
