Cal-Hypo raises CH as well as adding chlorine.

Ok. Makes since. I dumped a ******** in it as seen on the logs... I assume I should probably use liquid chlorine... I will be adding sense and dispense this winter for next winter... I am done with this chemistry experiment and will let the Hayward Omni manage it more than me!

Watch your Calcium Saturation Index (CSI) - Trouble Free Pool. Your CSI is often above 0.3 and your pool is at a risk for scaling. Best to run it between 0 and -0.3.

Lower pH and TA until water temperature starts dropping. High water temperature raises CSI. So you need to balance the two.
