Conflicting results

[ronschuster]

I still have my Leslies/Taylor "Deluxe" DPD kit and I recently started to use my new Taylor K-2006. I've had problems with CC for weeks so I tried using both kits. Shouldn't they give similar results? This evening with the K-2006 I got

FC 1.0
CC 3.0
PH 7.6
TA 150
CH 260
CY 40

The DPD kit gave me
FC 2
TC 3
(CC 1)

For exact numbers trust the FAS-DPD test in the K-2006. Either way you have a CC problem, though fixing it might be as simple as adding enough chlorine to get up to the high end of the normal range, i.e. FC around 7 or 8., or it might mean that it is time to SLAM the pool.
