I'm on my second Icecap 3K power head. The first one had a loud humming sound new out the box. Coralvue sent me a replacement motor. Changed everything over, was Quiet for a about 2 weeks now 3 weeks later sound is back. I've had better luck with the gebo pumps then icecap. Wish i could return everything back to coralvue.

My 3k was loud when I got it. It had air bubbles in the propeller. I adjust the propeller until the air bubbles are gone. Then the noise went down significantly.

My experience with these are, work great/fine in the beginning, after a month or so, they start to make noise and stay making noise. After there Is any algae build up in the propellers, their flow drops dramatically.

I agree with this. I've used all versions of the gyre pumps and I think the Jebao seems to work the best. It's never had any issues and is still quiet after yrs of constant use.
