I did a self install of a Pentair IntelliChlor 40 in my pool in August of last year. Install was really easy. I kind of went with a cell that was way more than what I needed for the size of my pool. I figured I could run it at a lower power cycle for my pool, and the cell would last longer that way. Cost wise between the IC40 & IC20 was minimal, so I just went with the larger cell.

The reason I picked Pentair over the others, was because the rest of my pool's equipment is Pentair brand and I TRUST the brand.

I'm completely happy with the results and how the IC40 has kept my pool sanitized. The pool never looked or felt so good, with so little manual labor or chemicals. Pool just needs a few oz of Muratic acid every few weeks to keep the PH under check.

Since, I'm also new to the SWCG, I don't know or have experience with the other brands. But, I sure glad I went with a SWCG system. One of the best upgrades I've done to my pool.
