Aqua Blocks™ are an attractive way to keep your pool's winter cover in place all season long. The hard plastic construction offers a more durable solution when compared to vinyl water bags, which may rupture or leak.
Aqua Blocks™ are easy to use. Simply place the Aqua Blocks™ around the edge of your pool cover, fill with water from your garden hose and snap on the top lid. In the spring, simply remove the lid and tip the Aqua Blocks™ over to drain. It only takes 32 Aqua Blocks™ to hold down the cover on a 16' x 32' swimming pool.
Set of 20 Aqua Blocks™.
NOTE: Aqua Blocks™ are not designed for round swimming pools.
