I waited a while after buying this to write a review; honestly it only took a few days for me to realize how much of a difference in water temperature this thing makes. Our pool went from warm soup temp to inviting and refreshing cool temp in less than 3days of continuous use.For reference we have a partially sunk 18×33 above ground pool full exposed to the south Texas sun. The size of the pool is why I went with the double sprayer. Important to note that it took some fidgeting to get the fountain pressure and circulating pressure just right but now that it’s set we have good water circulation in the pool and ample fountain spray to maintain the temp in above 100degree temp with feels like temps above 104degrees.Everyone I’ve shared the product link with, also live in South Texas, has bought one and loves it!
