Pool safety covers do more than just keep the leaves out. The decision to spend the money on a nice form fit cover is sometimes hard. But the cost to not cover your pool is much higher. Not only does a cover keep out debris, it also keeps out the UV. UV is the most detrimental to your pool. Especially fiberglass pools and vinyl.
By covering your pool with a quality safety cover, you completely eliminate the possibility of an accidental drowning. Unlike the covers of old where is was just a large tarp held down with water bags around the cooping of the pool. The mesh covers of today are all held in place with stainless steel tension springs that hook to retractable anchors set into the concrete. This enables the pool covers to hold over a thousand pounds which out caving in or damaging the cover.
