I've just started up my newly-filled hot tub, and am getting to grips with a Taylor K-2006 test kit.
The various chemicals are not quiet in check yet, but the CYA is constantly coming back as "infinity"!
My test sample, when mixed with the CYA reactant, simply does NOT turn cloudy!
My 1700 L tub has had 450 mL of liquid "Stabiliser" added, and still no cloudiness to the sample!
I am worried I may end up putting too much in, but it just isn't registering on the test!
Might I have a faulty CYA test reactant..?
Any suggestions would be greatly appreciated.
