I'm not really sure what is causing my problem but I am fighting my annual green pea soup problem and I'm at the point where I can see the bottom of the pool now.

However, my DE filter starts out with a pressure of about 5-7psi and rises to 18-20 in about 1-2 hours and the flow of water is stopped.

I can bump and start again with a pressure of 5-7 for another couple hours and then the pressure rises and the water flow is stopped again.

I am battling a small suction side air leak somewhere that is causing some bubbles to show up in my return jets and pump basket lid. Is this air eventually overwhelming my pump with air or is it because my de has caught enough algae to have to be bumped?

I cant even run my pump overnight because after a couple hours the pump is just running but its not filtering water and I'm wasting electricity.

Thanks.
