To try to help warm up our small 12 ft Intex pool, I recently purchased this Intex solar cover. In this video I show how much of a difference the cover has made over the few weeks that I've had it on. In short, the cover has helped to warm up the pool and to keep it warm with the increased temperatures that we've had recently. While it doesn't instantly warm your pool, after using it for a while I can say that it does help to warm it up and keep it warm over time. And the more sunlight you have hitting your pool during the day, the better it will work. Alternatively you could also use black garbage bags on your pool surface and they would work similarly to a solar cover. But I'd rather have one cover that I can remove easily and for a 12 ft pool the actual solar cover wasn't too expensive. Check it out using the link below.
