    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 2 out of 5 by from Unhappy I'm sad to say that this product sucks . I had great hope for them. Upon arrival 2 had cracked tops ,still usable but cracked. I just looked out at my pool to notice that (it looks like) 3 have fallen into the pool a issue I will have to deal with tomorrow as it is now dark . Unhappy that nasty leaf water is now in my pool.

      Rated 2 out of 5 by from They break I bought these this year. Thought they would be much better than the normal tubes. Opened the box and one was cracked. I bought 12. They are hard to lock. Do not stay closed, must use ties to keep them closed. Not sure if I will buy them again
