Had to pick up some chlorine yesterday, so I tested the testers.
They had just tested someone else's water - no rinsing of test tubes - just "dump 'em and on to the next" (me).
I had tested just before leaving home - store is 1 mile away - same EXACT water sample:
TFTestkits Pool Store
Cl - 9.5 5.0 (they don't/won't do a drop test) (am coming down from a SLAM)
pH - 7.5 8.0
TA - 80 120
CH - 300 380
CYA - 40 40 (yeah - they got ONE right!)
So, if anybody needed any more proof of how our method works - here's a classic example. My water is sparkly crystal clear.
Of course, they offered to check for phosphates (declined) and did give me a TDS of 1600 - because, well, it's important --- NOT!
On a side note, my chlorine was being eaten up a a pretty prodigious rate - 2-3ppm/24 hours a week ago. Discovered the culprit - dang Polaris Bag! Pulled it out and soaked in chlorine for 24 hours - now the ONCLT - less than .5 ppm overnight with .75" of rain! Happy camper.
Have a great Sunday everyone!
