At first it wasn't working we had to def. use the kit that it comes with. Works fine and doesn't slow the filer down at all. I have a 15x30 oval pool and it def. needs another one of these solar domes. So when you buy this and you have a big pool like mine, buy 2. Otherwise it won't heat it on it's own.
I bought these two adorable Yellow duckie inflatable swimming pool arm floats for my 3 1/2 year old granddaughter. These are her favorite as she can float but feels free to move.
