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.
It was a nice addition to our pool and it is working very well. Once we get the solar heater in for the pool it will be perfect. Now that we have had the cover on for a few weeks, we have decided we don't need the solar system for the pool. We are very happy with this product.
It works great to heat up the pool, but the slats do not align properly if you have a previous installed one and you are using it to replace one of the old panels
