Usage Notes. Many authors of usage guides, editors, teachers, and others feel strongly that such âabsoluteâ words as complete, equal, perfect, and especially unique cannot be compared because of their âmeaningâ: a word that denotes an absolute condition cannot be described as denoting more or less than that absolute condition.
A solar blanket or solar pool cover gives you free heat from the sun. They are somewhat similar to bubble wrap (only made with more durable material). You can buy this in big sheets that you cut yourself to fit your pool. These are definitely the most economical way to raise the temperature of your pool.
While these products may raise the pool temperature, they do so by reducing heat loss (mainly at night). Solar blankets should not be left on a pool during daylight hours, and at the very least, they should be removed for a 4-8 hours during the day for the pool to breathe. For those who do not wish to drag a cover on and off a pool everyday, there are many liquid additives that help retain heat by reducing evaporation.
