What kind of Intex pool do you have? I used to have a 15' donut with the little 1/6 hp cartridge filter. I had very little trouble hooking up a 10'x4' solar panel to it, just using that little pump. I did have to get fittings to mate 1.5" plumbing required by the panel to 1.25" plumbing used by the pump and pool, but that was it. By adjusting down the flow to the panel I maintained the water velocity necessary on the return and STILL had the panel bring the pool temp up to over 100 deg!
