Just Curious on Chlorine Consumption

[auto]

Seems as thought the pool is sucking down about .5-.75 gallons of 8% Chlorox every day... and I am wondering is the normal due to UV? PH does vary between 7.2-8.0 and add Muriatic Acid about twice a week. Thoughts??

FC-4.8
PH 7.6
TA-105
CH-250
CYA-40

That sounds kind of low to me.

I don't see your volume, so I can't work it out in ppm per day, but my pool is essentially 12X32 and it's 16000 gallons and I use a quart of 12.5% per day. Your pool is bigger and your bleach is weaker.

It can be. You could perform a OCLT to be sure it's not something else. Also is your CC less than 0.5? If it's neither of those and your pool is clear, you could bring your CYA up to 50. I just recently did that after losing 4ppm of FC a day. Now I'm at 3 a day.

20K is what the builder said, I can always go back and look at the water bill for when filled. Pool is clean, clear and light chlorine smell. Will test the CC, and then try and raise CYA to see if I lose less Chlorine.

Plugging 20000 gallons into poolmath... half a jug (not a gallon) of 8.25% bleach is 2 ppm. That's normal loss.
3/4 jug is 3 ppm, also well within normal. I don't think you have a problem.

Thanks... Not that much in the fall and winter, but with the increase in temps seemed a little much. Thanks for the sanity check.
