All pools without an automatic cover will need a mesh winter safety cover installed at closing. Aqua Blue sells and installs winter safety covers from the best manufacturer in the business, Loop-Loc. You will like the appearance of the pool all winter long and the cleanliness of the cover compared to the old water tube covers of the past. The mesh allows water to pass through and the debris to dry and blow off all winter. Plus, the covers are "safety covers" protecting children and pets all winter long from falling into the pool. Loop-Loc covers block out 99% of the sunlight to keep the pool clear.
