I am just starting to have my 25000g inground pool resurfaced and I am replacing all the equipment to Pentair products. I initially purchased the IntelliPH system, but then realized that Intellichem would better suit my needs. I bought the Intellichem 521357 with flow sensor; can I use the acid tank that came with the IntelliPH (521377). I ask because there is a two prong plug on the acid tank wire- can I remove that plug to hardwire the acid tank pump into the Intellichem? I purchased the IntelliPH from Ebay and cannot return it. I was hoping I can integrate the tank to with the Intellichem without having to buy a different tank.
