Today, the PB and an official Hayward tech hooked up the Hayward Sense & Dispense system that has the ORP & pH sensor.
We also hooked up the Stenner pump that is dispensing a diluted 2:1 ratio (2 H2O + 1 Acid) of 31.45 baume Muriatic acid.
So, prior to configuring these, I had balanced the water to 7.5 pH, 5 FC, 0 CC, etc.
The (awesome) tech from Hayward then spent a lot of time to configure the system.
The system has been running for 3-4 hours now and I am seeing a constant 7.5 pH and 5 FC
Upon reading extensively on the topic, there were topics that say that an ORP + pH system works well with a CYA level of ZERO!
To the non-chem-geek like me, if we are constantly dosing the pool with acid trickles and SWG chlorine, albeit, in small amounts, why do we need CYA?
In my new pool, I have 55 CYA and hope to keep it at that level, but is it beneficial to allow the CYA to come down in the future?
