I saw this today at Walmart kit and it made me curious because people had been talking about these costing close to $1000. I wondered if anyone had experience with it because it's pretty inexpensive. Also, it is designed for AG pools but I don't understand what is different for an IG pool since you are using your original pump right?

I've never used SWCG before.

Hope it's ok to post the link, I didn't see any rules against that.
