Disposed of several pounds of dry ice into the pool. I expect the pH will drop quite a bit.

The gallon of 10% LC added was over 3 months old. So it acted more like 6%. While the 12.5% from eKonomy is a lot more expensive, it’s at least fresh.

Lost a lot of FC today (~ 10ppm) but I suspect that’s due to my very low CYA levels (< 30ppm). Bringing CYA up with 3lbs of stabilizer, dichlor shock, and trichlor tabs in a floater. Will perform an OCLT to see how the pool responds to no UV loss.
