At the time i needed a replacement amazon was not directly selling the blue wave ns115 8mil solar blanket for round aboveground pools 21ft blue that i had purchased three years earlier

When i opened the box it was shipped in one of the first things i noticed is that the bubble appeared to be smaller than the one on blue wave blanket and perhaps that contibutes to the not floatin

First it just does not heat the pool nearly as well as the 8mil blue wave
