Was going to buy a cover for my spa to slow FC loss when I go on a week vacation for a month. Is a black solar cover (the one with the bubbles) ok, or should I get something else? Will black slow loss more than blue or clear?
Also, I have a freeform spa, and was wondering if I can cut one of those covers with scissors to the shape I want (never seen a solar cover, so not sure).
