Will continue to monitor pH and add acid to reach a lower TA. Will continue to maintain CSI at -0.3 to 0.0 to avoid SWCG cell scaling.

Attempting to lower TA. Adding acid to drop pH to 7.2. Will let pH drift up naturally then drop it with acid again.
Per TFP, keep CSI between -0.3 and 0.0 to avoid scaling. Will need to lower pH to do that. Lowering TA will help with keeping pH under control.
FYI: Home Depot only has “weak” 14.5% acid now. Got 31.45% acid at Ace for a better price.

Low Salt light was lit. Checked salt level: 3400ppm per drop test, 3150ppm per meter, Ok on both. Pressure was over 20psi on Spd1, so backwashed filter. Now light is out and 15psi at Spd1.
