Blue Wave 8-ft Water Tube for Winter Pool Cover

Good price for 5 tubes and free shipping. Like everything now a days prices are high. I've use this brand for years and they last several winters.

We got 12 of these to hold a winter cover over our 16'x30' pool while a new screened enclosure was constructed over it to replace the one crushed in hurricane Irma. They did the job well. Only 1 of the twelve had a slow leak that required us to refill the tube every 4 days. One got punctured by the workmen tearing down the remains of the old cage, but I patched it with a bicycle tube patch and all was good with it after that. They were only in use for three weeks, so I can't say how they would do over an entire winter, but for our purposes of keeping construction debris out of the pool they served well.
