How much bleach do you go through?

[PhantomAndy]

I have full sun on the pool from 9:30am until 7:00pm for most of the summer months. It was a little lower consumption on cloudy days, and I never had my pool covered last year (solar cover delaminated over winter).

I carried 40-50 ppm CYA - and it drifted from around 3-4 ppm after adding the bleach to .5 to 1 ppm in the evenings.

I was surprised about the speed of the loss as well, but I never had any CC in my pool last year - and the waster was crystal clear all year long.

Andy, this seems to be exactly where I'm at right now. I have measured CYA at 40ppm twice but I'm losing 3ppm - 5ppm of CL in the light of day - virtually nothing overnight. At 35,000 gallons, that's 3 gallons of bleach/day. No CC either right now and water is crystal clear. I got my CYA down from 100+ since last July and converted to bleach in August. Didn't have any trouble holding CL the rest of the summer - went through 1 gallon every other day to hold level required for my CYA.

But....Bleach becoming a real pain at this usage. Makes me think my pool "likes" or needs more CYA or I'm not accurate with my measurement. Will try to get pool store to test for confirmation.

When it is sunny all day, I use a 1.4 gallon jug each night. Less when it's cloudy. My pool also has direct sun all day and I don't use a cover. My CYA is around 40.

I purchased a SWG recently because I don't feel like dealing bleach.

This is my first full season. Granted, there's been a lot of junk in my pool this spring, but I'm adding about .75 gal per day to a 21,111 gal pool. That's a lot of trips to the store and empty plastic bottles.
