Well, I'm testing it in a pool right now and getting weird results:
Location: Phoenix, AZ (Arcadia/Biltmore neighborhood)
Volume 12,500 gallons
TDS 800 PPM
Test tool: La Motte DPC2 Colorimeter, also checked on Taylor K2005 Kit
Date Cl PH CYA Temp Time of sample Time of test
4/18/15 6.0 172 68 8:00 8:30
4/20/15 5.0 8.0 182 70 8:47 9:00

4/27/15 0.5 7.8 200 68 8:37 8:55
Pool equp:
TR-60 sand filter, Pentair dial valve Pentair Intelliflo pump, Hayward pool vac connected at skimmer with Vac-Mate
4/20
Administered 8 oz package. Ran pump at 2450 rpm, 2" plumbing tr60 sand filter, no backwash, 4 hours. Dissolved contents into bucket and poured around the pool 3 cya tests took average
4/21
Cl and ph test taken on site with Taylor K-2005 test kit. 1/2 gallon Acid diluted in bucket and poured around pool
Only 1 of 3 tests measured consistent with previous tests. Other two were 20ppm higher tested on la motte dpc2 colorimeter
4/25
No significant drop in CYA. possible high chlorine on initial treatment. added second dose through skimmer this time.
4/49
Test showing slight increace in CYA, Results taken with Taylor kit show comparable turbidity and results to La Motte test
