LC Strength Test - started at 2.6ppm FC and added 128fl oz of 10% LC (PoolTime brand from HD). FC increased to 9.0ppm after 1 hour.
9.0 - 2.6 =6.4 ppm
Expected effect of additions was 6.2ppm.

CYA is roughly unchanged over 2 months (reading higher in fact now) which tells me there is definitely no leaks as it would have fallen. 50ppm to 60ppm consecutive readings isn’t odd given that the test easily has a +/- 15ppm tolerance and the water samples are different temperatures (20°F colder on the second read) .

Dropped a block of dry ice (~ 1.5lbs) into the pool.

Just recorded a big drop in CYA, ~20ppm in 15 days. Very odd. But I have been noticing higher rates of FC loss and had measurable CCs a few days ago.

The last batch of LC from E-Konomy pools was not giving the correct FC rise and I’ve estimated it to be almost half its advertised strength. Instead of 12.5% it’s more like 6.5%

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