I am about to install a new pool this week and one of the questions I keep going back and fourth on whether to get the Hayward Sense and Dispense system. My dealer says that the CO2 system is being phased out and that Hayward is recommending the acid feed system for PH. I have read that there are lots of issues with the ORP for Chlorine as well. My dealer said he has the Aqua Rite Pro without the sense and dispense on his own pool. So I need help! Any recommendations? I am trying to pick low maintenance, but don't want to pay for a system and I ended up doing what the system is suppose to do.
