    SwimmingpoolAZ bio-active cya reducer results

    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
    4/21/15 3.0 8.3 180 72 8:46 9:05
    4/22/15 2.0 7.3 165 70 9:00 9:15
    4/23/15 1.5 7.4 165 74 2:38 2:50
    4/24/15 1 7.4 180 72 9:05 9:15
    4/25/15 0.5 7.6 165 70 8:37 8:55
    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

    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

    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

    No significant drop in CYA. possible high chlorine on initial treatment. added second dose through skimmer this time.

    Test showing slight increace in CYA, Results taken with Taylor kit show comparable turbidity and results to La Motte test

    As far as I can tell, we have had 1 member post up results that appear to show the CYA dropping (although still not to acceptable ranges) and many who have shown no change.
