I added two more sungrabber solar panels to my semi-inground pool (with 1/2 HP self-priming superpump) and now the pressure in the filter is too high and the return flow is way too low. The directions for the panels says to add a tee and a valve to direct some of the flow away from the panels and back to the pool. But won't this reduce the heating affect of the panels? Is my only other option to buy a bigger pump? If so- how do I determine which one is right (3/4 hp, 1hp,...etc?)?
Thanks for the advise in advance...I should have just bought a propane heater!
