How much bleach (or liquid chlorine) per day is typical?

How much liquid chlorine usage is "typical" for folks in the hot and humid southeast in the summer months.

There's no general answer to that.

• The PRIMARY, NORMAL loss of chlorine is due to sunlight, so loss is a function of hours of sun vs pool surface area: big pools lose more! Also, having correct stabilizer and chlorine levels matters a LOT. Your stabilizer should be 30 - 80 ppm (higher levels can be compensate for) and your clear water (no current problems) chlorine level should be 5% of the stabilizer level.
  
  
• The BIGGEST loss is from runaway algae, and can be 20 ppm per day or even higher.
  
  
• A LARGE loss of chlorine results from 'people goo' -- sweat, spit, snot, pee, poop -- with urine typically consuming a LOT of chlorine.

Also, pool store chlorine can be 'stale' so that a bottle of "10% chlorine" may REALLY be 5% or even lower. Here's a better option for many people; Pool-Essentials-Chlorinating-Liquid carried by many Walmart stores. (MOST pool chemicals by Walmart are NOT recommended; this is an exception, and their bleach is likely to be 'fresher' than a pool store's).

All that said, IF you do everything right, via the BBB method, THEN daily chlorine consumption will typically range from 1 - 3 ppm, depending on how much people USE the pool.

My daily chlorine losses run from 1-3ppm, depending on the season.
