Sicce psk 600

[gkf]

Guys I need some help with this pump. Sicce calls these quiet pumps bs . This is the loudest pump I have ever seen.
First bought a psk1000 way to strong ordered the 600 and it growl's from its air intake so loud I need to unplug it. If this is the way these work they are unusable.
What if anything can I do?

Are you using this as your return pump? If so, why does it have an air intake? This would only be needed to run a skimmer. Remove it or submerge the end in water, and it should be virtually silent.

Thank you
Sorry I should have said that. It is on my skimmer that had a psk2500
I have tried just about everything

There are a couple options that may help. If you have any old pill bottles, you could make a DIY skimmer silencer from one. You can also put a small ball valve on the air intake line to control the air flow to the skimmer. A combination of the 2 would be best. It is amazing how much quieter it will be with the pill bottle silencer. Watch this video to see how to it is made.

Another option, if possible, is to run the airline outside. This will help keep pH up at the same time.

I watched the YouTube vid and thank you so much I will try that.
Another thing I changed the tubing to a 3/8 silicone hose which is a little larger then what was on the skimmer

Ok I tried the pill bottle no change.
Ball valve with no change.
Ran hose 10 feet no change.
Ran hose 25 feet little change.
Clamped the hose off and silent.
But then no skimming
I am not happy at all with this garbage

Tonight I played with this again and after a email to sicce where they mentioned to change from the 3/8 I'd tube for a 5/16 I'd or from 8mm to 6 mm . I have silicone hosein many sizes so I used the 5/16 I'd and slipped in a reducer in the line to 1/4 and made the biggest improvement so I removed the reducer for next smaller 3/16 and that did it .
Pump is silent now.
But if it needs that little air why are the Venturi port 3/8?
