Which solar stuff can help my pool get warm?

Question

1.Solar Sun Rings 2.Motorized Solar Fish 3. Thermo-Tex Solar Cover. which one is best. and will be take how long to warm up water

Answer 1

None of those actually. #1 and #3 will keep heat in nicley, but don't add much heat themselves and #2 is just a gimmick.

A proper roof mounted solar system, on the other hand, WILL give you heat but you're wise to use #'s 1 &2 with it.
