Hello All,
I have the hth 5 way drop kit from walmart. At the moment we only have an Intex donut 16'round. I test cl and ph everyday. I ran out of the CYA reagent.
There are 2 pool stores in my city. They do not have CYA testing reagent drops.
I have been searching on line and have found several sites to buy the CYA reagent drops but I don't know if they will work for my hth kit.

Can anyone give me a heads up?

Thank You for Your Time,
~Hoffmans
