After many years at my home and going thru a fiberglass in-ground and later free standing spa, I am at the end stages of having an in-ground pool and spa. I have an Pentair IntelliCenter installed with Pentair equipment with the exception of an Aquaqal LARGE heater. When seeking info, this blog came up a few times so I am happy to be joining. Looking to learn first and then maybe contribute knowledge later.
