I have a little 12x30 Bestway pool. I just upgraded to a 1500 gph pump, and got a solar dome pool heater and an Intex surface skimmer. I thought 1500 gph would be more than enough for my little pool but I can barely get the water to move around the skimmer. I have a flow restrictor on one of the inputs but it fits really loosely inside the cage. Would my skimmer work better if I took a 1 1/4 inch expansion plug and totally blocked off the 2nd inlet? Or is there a way to run 2 pumps at the same time dedicating one pump to the skimmer. The other pump to my solar heater? I have a 100 gph pump I was going to return but could use. This 1500 is the 2nd pump I’ve gotten after realizing how bad the pump was that came with the pool. I really don’t want to send back the 1500gph but should I have gotten a 2500?
