Hi

I installed some black solar heating tubes to my inground pool. Filter pressure before was about 10 now its 20. The heat tubes are about 1/4" and on top of my ramada. I am wondering if I go from 1 hp pump to 1/2 hp pump will that decrease pressure? The pressure in filter makes the airbleed on top leak a bit and the pressure can't be good for the pump. Filter is DE and pressure stated is when cleaned.

Thanks for any answers or suggestions.
Tom
