When (if) I get my cya down to 50ish, I want to experiment with this process. I can get a 53 gallon drum of 12.5% liquid chlorine for $193. It doesn't come with a dispenser, so I'll have to rig something. Any ideas are welcome. The state laws don't restrict hand feeding. This pool never closes, so what are the logistics for adding the chlorine? Right now we use chlorinator (now with unstabilized pucks) and the pumps run 24/7 so we get a steady feed. Currently, if I needed to do an old fashioned shock, or use algicide, it's done in the early morning before the swimmers show up.
I think I read that with TFPC it is most effective to add the bleach at the end of the day. If my cya is 50, my min fc is 4 and target is 6. The water is clear; everything is humming along. So I measure my chemistry in the am and I'm at fc of 4. The math calculator calls for 1.4 gallons of 12.5%. Do I wait until the pm or add it in the morning? How long should I wait before it's safe to re-enter the pool?
I inherited this pool, along with its procedures. Thanks to this site I'm rethinking things, but it has to work in the context of keeping the pool open at all times, so I'm somewhat hobbled.
I'm interested in hearing from the seasoned veterans that post here. How would you do it?
