    No More Leaky Bags ─ Hold Your Winter Cover Securely with Unbreakable Aqua Blocks

    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.

      Rated 4 out of 5 by from Easy filling and nice looking They work better than the pilows. Birds or dogs cant punture them. I do tie them with a string just to make sure the wind doesn't blow the cover off,even thow they snap on. Need to fill with water by cover as the arent strong enough to carry.

      Rated 5 out of 5 by from Well made Trying these for the first time. The water bags only last a couple years until the ice causes them to leak. They are very well made so they should hold up.
