Hi,
I'm hoping someone like chemgeek can help.
I had been using a Taylor Technologies based test kit (from Clear Choice Labs here in Aus) which for Calcium Hardness uses R-0010, R-0011L & R-0012 reagents. I have confirmed the validity of these results using the Taylor Calcium Hardness 200ppm check standard. For my pool specifically, I generally test around the 300ppm using this kit.
Now this is where it gets confusing, and I can't for the life of me figure out what is happening. I recently purchased a Palintest Pooltest 6 photometer which also performs a calcium hardness test. Following the instructions exactly, I get a result of 135ppm. Vastly different to the 300ppm I get from the Taylor titration kit.
Given the difference, I sent my Palintest back to the manufacturer to confirm calibration, and it tested well within calibration standards. In fact it tested exactly to the required standard.
From what I understand the Taylor Calcium Hardness test is Calcium Hardness only, and not total hardness. Is that correct? I'm not sure what's going on, but the difference is significant and either means my CH is exactly where I want it to be (300ppm) or I need to add 8kg's of hardness increaser to my pool. I definetly don't want to add that unless I'm 100% I need too!
Current Test Results:
FC 1.6
CC 1.6
PH 7.6
CYA 15 (due to ORP probe. CYA interferes with this)
TA 80
CH either 135 or 300?
