Chlorine is an important part of maintaining any pool. I've read horror stories of people buying chlorine from pool stores or big box stores and the chlorine being ineffective.
If stored long enough Chlorine can degrade, lose it's strength. If put in the sun i've read that it can speed up that process.
Like most pool owners, I have a pool test kit that tests how much chlorine is in a pool water sample. I specifically own a Taylor K-2006c Kit which test for Free Chlorine using the FAS-DPD Method.
At most pool stores they supply 12.5% Sodium Hypochlorite and 87.5% Other Ingredients.
With my given test kit would it be possible to accurately test whether or not it's actually 12.5% Sodium Hypochlorite or not? If so, how would I go about doing so?
If not; What do you recommend using in order to test the chlorine.
