Re: How much chlorine does shock add
I have a little chart published by Taylor which came with one of the test kits I have. The title is To Raise Chlorine 1 ppm Using Chlorine Compound
and then gives a number of percentages of available chlorine across the top of the table and pool volume down the y-axis.
For 65% available chlorine it shows 2.05 oz for 10,000 gallons. If you input 2.05 oz for 10,000 gallons in the Pool Calculator it says it'll raise FC by 1 ppm. So, we have agreement between those two sources of information.
In my personal opinion and experience, the bulk chlorine is the most economical, efficient, and controllable product. The liquid chlorine I buy starts out at 12.5% when manufactured but tests at 11%. I refill it into old bleach bottles to make it easier to handle.
Ultimately, you'll use whatever is most convenient and effective for your specific situation. Plain chlorine at whatever strength is definitely the easiest to manage but yes, hauling and disposing of all of those bottles can be a drag. It's too bad that store is so far away from you.
