Need some guidance folks,
I purchased the TF test kit and can not get a CYA reading.
Its not that it is too high, but I can see the black dot right up until the vile begins to overflow.
I have some aquachek test strips I bought for just quick spot checks (I have nothing good to say about their indication) and although difficult to get a real reading, it looks generally low 30-50.
I purchased some stabilizer to add from my local pool store and after some insistence from the owner that a pool as old as mine couldn't possibly have a reading that low, I brought in a water sample.
They claim that the CYA reading they got is at "100" and I don't require any stabilizer to be added.
I'm assuming that in the presence of a CYA value of 100 my water would be very milky looking after adding the reagent. This is not the case.
My PH is a little high (~7.8), but I haven't read of any factors that could cause my reading to be so low.
Am I missing anything here?
I have done three tests now and several strips and all show low ratings.
What should I do?
