Does this pH controller require other equipment to function?
larry s on Sep 16, 2020
BEST ANSWER: the PH controller requires a "power center". I have the pentair IntelliClor as well, so I was able to plug my PH controller into the power center I have the the salt system. I have had mine for about 6 week and I am very happy.
How much acid will it take to control 56000 gal. pool ?
Mary M on Feb 24, 2017
BEST ANSWER: It really depends on your environmental conditions (climate, temperature, evaporation rate, use level or body load in pool, etc). And for the same pool, it always changes too and must be readjusted (usually seasonally). With this unit you can program the maximum volume acid dispense option.
