When it comes to your pool, it is necessary to have some sort of a pool cover over the area of water to protect the water from collecting dirt and other debris. But more importantly, a pool cover also acts as a safety precaution. Many cities around the country actually require you to have a pool cover in place, just in case an individual or an animal wanders into the pool area and is drawn to the water.The cover is there to help prevent this, as are the various types of pool fences which can be installed around the pool.
Use a solar pool cover to keep heat from escaping your swimming pool, to prevent excessive water evaporation and to reduce the amount of chemicals you need to keep your pool water balanced. They come in 3 main varieties: bubble solar covers, vinyl covers and insulated covers. There are also liquid solar covers that you can turn to for 24-hour a day heat retention protection.
Although you keep your swimming pool clean and maintain the equipment, getting a cover for that pool will cut down on energy use and costs, evaporation, and save you time. It's just one of those things that, sooner or later, you're going to have to buy.
