I have a free form pool and never thought of using a solar cover because of the shape. But I’m also annoyed during the spring and fall when I can see the heat evaporating each morning. I’ve been reading a bit and know most people have used a large cover that they cut to shape but what about two separate large circles that won’t cover every inch of water but would cover most of it. I assume that’s better than nothing but has anyone tried this (partial solar cover) with success?
