Does anyone have any experience with the Pentair IntellipH control system. I was looking at the Pentair website and came across this device. I have not seen very many recent reviews on it. It looks like the device uses timers instead of a pH probe and operates very similar to the SWCG device cells. The more time on the more muriatic acid is dispensed, the less time on the less muriatic acid is pumped into the system. I was planning on cutting the muriatic acid 3:1 with water if possible. The lack of a pH probe is a benefit to me because with no pH probe, there is no pH probe maintenance. I figure that I will check the pH anyway in order to make incremental changes as it is being dialed in but at some point it should be much better than no pH control at all. In my reading it looks like the IntellipH uses the Intellichlor and/or the EasyTouch controller systems which I already have. It also uses the same safeties that the SWCG Intellichlor does. If there is no water flow then the device shuts down. I think another benefit might be that the Intellichlor IC cells can be turned down in increments of 1% instead of the normal 20% using the IntellipH controller. I have a spa connected to the pool so I would also want some kind of interlock to shut the peristaltic chemical pump down when the spa is in use. I don't have one of these yet but maybe someone can shed some light on the subject to solidify my decision? Any comments Pro or Con?
