My pool uses well water with high alkalinity. We have to constantly drip muriatic acid into the pool to keep that under control and pH balanced. We do pretty well with it but I'd like to automate. Anyone with experience on the the Pentair IntellipH and IntelliChem? Sadly neither the rep at my dealer nor at Pentair was really familiar with the 2 products. From my understanding the IntelliChem is supposed to sense your pH and automatically adjust the dosing. While the IntellipH just injects acid according to a dosage you manually control. How well do they really work - at least according to your experience?
