Created by a pool owner who was tired of replacing his winter cover weights every year, Aqua Blocks are for repeated use year after year. These three-foot-long blocks are made of durable black polyethylene with a UV inhibitor that resists cracking and fading.
To use, fill the Aqua Blocks with water and place them on top of your in-ground pool's winter cover around the pool deck. In the spring, simply empty the water and stack the Aqua Blocks inside each other for easy storage. These blocks fill easily and their lids feature snap-lock covers to keep the water from sloshing out as you're placing them.
