For those of you using Bleach...

14KG, 30CYA, Full Central Texas Sun, lose 2ppm per day, 0.33Gal /per day at night, I always add chlorine when in the late evening and lose less than 0.5ppm overnight.

I just bought the house in March, (1st pool) and I'm still improving my routine but it looks like it will be 64oz of 6% per day or more and about a 1.5ppm loss per day. (I have a pretty high CYA at about 50 and am maintaining the chlorine as low as possible at 3ppm.)

I live in South Houston so I'm way south compared to 90% of you. We've been getting a great deal of rain recently as well so I've had some mustard algae. (yeah yeah, more bleach is the answer but how much?)

Maybe it's different since I'm so far south but I'd LOVE to know -when- people are adding their chlorine. I totally agree with Ben that adding it in the evening should let the chlorine get it's job done overnight before the sun starts to destroy it in the morning. It would be nice to have a chart of people's responses to look for trends in chlorine consumption.

Oh and, Thanks to everybody! I think I have almost as much fun running the pool as swimming in it!

19,000 gal AG pool, North Carolina, ~70% sun, light bather load, just a few leaves after a storm and a few bugs here and there, CYA 30, and 2-3ppm chlorine loss per day.

24' AG (approx 15,000 gal), CYA 25, full sun all day. Averaging 1 or 2 ppm per day, but the hot sunny days when the boys are in the pool all day requires 3 ppm. Moderate swimming load - somebody usually goes in every day.

Great thread!! I/G Plaster 22,000 gal outside the Motor City. 10 hours direct sunlight, CYA 30, medium bather load, lose about 2ppm per day.

Here's some more info for your table (under "chem_geek"). The pool is 16,000 Imperial Gallons. I would describe bather load as "light" with only one bather about 3 days during the week and two bathers 1 or 2 days on the weekend.

Having a pool cover makes a huge difference in chlorine consumption. My chlorine level is between 2-4 ppm (remember my CYA is only 15 ppm) and that probably helps as well.

1-2 ppm every 2-3 days when weather is fair.
Light bathter load, CYA <30, 24K vinyl IG 18x42, outdoors, full sun from 10 am til about 4 - then the shadows draw longer. Pucks at start of season, bleach only now. Alk has held fast between 70-80 since opening in mid-May, pH around 7.5 as far as I can tell. Having problems decipjering color endpoints on the pH test with my K2006.

Was very hot yesterday & today, had 3 kids over yesterday. Added 3 qts plus 1.46 galls belach and a lb of Borax last night. FC was 8, CC .5. Today at 3 FC=4, CC=0, all others the same. H2O temp of 86 with no cover.

[Mom2Czars]

24' AG pool ~13.5k gallons, light to medium bather load. CYA is ~10-20 (still waiting to test it again). Full sun from around 9am to 5:30pm. It's losing generally 1-1.5ppm of chlorine a day. We've had abnormally hot and humid weather for the last several days and my pool temp is currently up to a balmy 87. I'm hoping for a bit of rain tonight to bring the temp down.
