I dunno, but out of curiosity, did you check the hardness regularly
before you drained it? I'd be concerned it's the plaster.

Leslies always tells me that the hardness is on the low side.

Here's my last report:
5 ppm Free available chlorine (HIGH, should be 1-4ppm)
5 ppm Total available chlorine (HIGH, should be 0.2 difference)
140 ppm Calcium hardness (LOW, should be 200 to 400 ppm) == add 28
pounds 4 ounces of Calcium Chloride
55 ppm Cyanuric acid (OK, should be 30 to 99 ppm)
90 ppm Total Alkalinity (OK, should be 80 to 120 ppm)
7.2 pH (OK, should be 7.2 to 7.8)
1 Base Demand (no test results) == add 1 pound 4 ounces of Soda Ash
0 ppm Copper (OK, should be 0 ppm)
0 ppm Iron (OK, should be 0 ppm)
500 ppm Total dissolved solids (OK, should be less than 2,500)
100 ppb Phosphates (OK, should be below 100 ppb)
