Bleach vs Pucks

[Rangeball]

My pool has 21,200 gallons of water. My CYA is about 15-20. I have 2 ppm FC at dark, when I add .75 gal of 6% bleach, yes, generic regular clorox. This puts me to 4 ppm overnight, and I lose 2 ppm through the day, regular expected loss.

It takes me about 30 seconds to walk to my garage and get a bottle of bleach, about 5 seconds to get to the skimmer and remove the lid, 5 seconds to open the bottle and remove the seal, 12 seconds to slowly pour the bleach in, and about another 30 to replace the cover, put the jug back in the garage and get back into the house My pool stays crystal clear.

When I used pucks, I still had to put them in daily for best results, so this isn't an issue for me.

I have a 15,000 gallon plaster pool and add 3 cups bleach in the evening. This takes it up by 1ppm (to about 2ppm total) and I lose about 1ppm the next day. That's 24 ounces a day, so the 174 ounce jug of bleach lasts a week. CYA is about 25ppm.

One cup (8 ounces) of muriatic acid each day holds the pH steady at 7.4, so one gallon (128 ounces) lasts two weeks.

Clear blue so far.
