Hi...like many here I struggle taking the solar cover (15X30 AG Pool) off and on that I usually don't bother using it. I haven't seen a reel that is worth the money, otherwise I would buy one. I was wondering if anyone uses those 'fish' that slowly let out a chemical that supposedly acts like an invisible solar cover. Are they worth the money? I usually don't like to have anything (toys, etc.) floating in the pool while I swim but in an effort to maintain a higher water temp I would consider these if they are effective. Thanks in advance for your replies!
