Aqua Blocks
Aqua Blocks are unbreakable and are constructed of tough polyethylene. Aqua Blocks will not rupture or tear like ordinary water bags can. Aqua Blocks slip into the pool cover loops the same way as water bags and they are built to withstand winter.
Aqua Blocks are made of high-density U.V. resistant polyethylene and they are 4 times thicker than water bags and have no seams, so they won't split or crack due to the cold weather. Their handy design allows them to be nested together for easy storage when not in use. Compare that to cleaning and storing used water bags! Easy to use, just fill with water and snap on the top cover, locking it in place. Aqua Blocks measure 3' Long x 8" Wide x 4" Deep.
