Robelle 3Pool Cover Weights, 6-Pack, 8 ft.

More hold power than expected. We have a small oval pool that is about 30 feet by 18 feet and own an oversized pool tarp with straps. We were using landscaping bricks to hold down the tarp but it would still slowly sink into the pool as it rained. We purchased (6) 8 foot water tube and (2) 10 foot water tube. We used the (2) 10 foot ones on the long side of the pool and the (6) 8 foot ones around the oval curved areas. See attached picture. We likely over purchased on quantity as the pool parameter only have about 8 1 to 2 foot sections without a water tube. However, since we purchased in bulk on amazon it was fairly cheap. The best surprise was that the water tubes could be positioned along a curve. We did not use the pool tarp straps for the water tubes and instead opted to curve around the pool oval parameter to allow for more walking round around the pool in the winter. The curved solution was the best looking pool covering we have had in years. The solution we have can hold about 6-8 inches of water on top of the pool water surface and not cave in. We were really impressed. This means we no longer had to rush to place the a pump on top of the tarp after it rained in case if caved it. We even left for a 10 day vacation without worrying to ask a neighbor to check on the pool. The only time the tarp caved in on a section of the pool was when a friends dog (70lbs) got on the tarp to get a bird. The dog’s weight was localized and not spread out so a corner of the tarp came out from under the water tube. The water tube is made of strong material and does not easily get pierced. We only have one hole from the dogs nails and she ran around the pool all winter. The hole was easily found and patched with a bicycle tube patch for less than a dollar. The have used the patched water tube the following winter and the patch held up. The red end caps are a bit hard to close, but my husband can easily close them after I fill them. We store the water tubes in a shed out of the sun when not in use and so far have not had any issues with quality.
