I am ready to switch to the di-chlor/bleach method of sanitization.
Just want to make sure I am figuring this correctly.
For my 330 Gal sap, PoolMath says that 10ppm FC is about .8oz di-chlor
Since 10ppm of FC via di-chlor raises CYA by 9ppm, I should be adding a little over 2.4 oz of di-chlor to get to the appropriate CYA level (I can always test with my TF-100).
SO, if I set aside 1/3 cup of di-chlor (about 2.6oz), I should be able to use it to sanitize and when it's finished, I should switch to bleach. My target would be to keep FC at 5-6ppm with the bleach. but never drop below 3.
Does this plan seem reasonable?
