Morning All,

So yesterday, I thought I would give it another try at the pool store since it was raining here (seems like that's all it does) and I thought that I needed some CYA and some Calcium. I have to regularly take water out due to the rain.

Here's their numbers:

CYA 100
TC 2
FC 2
pH 7.8
TA 90 (with adj of 60)
hardness 205
salt 2100

here's my numbers with a 234s kit

CYA 45
TC 4.5
FC 4.5
pH 7.5
TA 80
Calcium 260
Salt 3000


What concerns me is that with the exception of TA, we weren't even close. I test every week and typically pH is the only thing that fluctuates unless I need to drain, which I have. My numbers typically don't change much except for salt, CYA, and calcium have been going down as you would expect. I've added salt.

I also have brought my TA down to 80 based on some of the posts here and at another forum.

I tried to explain that TA acts as a pH buffer and that I have intentionally lowered it. When she went over the list of everything I should buy and add, she commented that, "I guess you don't want to add this to raise your TA. Just be careful that your pH doesn't get to low". I chose to not respond at that point.

My concern, is it possible that my kit has an issue? Especially the reagents for CYA, as I measure it lower than I like to keep it. I don't want to add if it is truly 100. I went through that with salt - adding too much and needing to drain to get it in line, I don't want to repeat.

Thanks,
Kevin

PS. Hopefully we all have a dry and wonderful Father's day.
