*UPDATE* I purchased the Taylor test kit (as above) and spent the afternoon running tests. Here is what I have come up with (some test I did more than once to make sure the readings were accurate:

FC = 5 ppm
CC = 0.4 ppm
pH 7.4
TA = 190 ppm CaCO3
Calcium Hardness = 420
CYA = was very high - actually could not get an accurate reading it was so high.

The water in the pool is crystal clear, so I hesitate to do anything to it, but I am very concerned about they CYA levels. I should add that I think there is a tear in the vinyl liner (near the deep end steps - needs to be repaired), so I have to add water to the pool about every 2 days, and after I backwash. The water in my area is very hard and very alkaline, which I am sure has contributed to the higher than normal readings. I see that it is recommended to use the BBB system, but I am not certain I understand how it works. Are chlorine pucks not used at all? If not, then what is used in their place? I'd hate to mess up the pool at this points, since it does look good. And other than turning our hair green (I also purchased the Culator product), the water SEEMS perfect.

Please help, as my kids spend a lot of time in the pool and it makes me nervous thinking that they are exposed to a dangerous environment. Thank you!!
