Should I be losing chlorine this quickly?

[DuchessJen]

Hi!
I live in Central Texas, where the sun/uv is intense and hot!
Should my FC be stopping by 2.5ppm over the course of 2 hours?

Gallons: 1715
Sand filter pump
Current chemical levels attached.

I also live in Austin and have a 2 month old pool so I don't have a lot of data yet. With that said I have been losing 3-4 PPM in a 24 hour period on sunny days. The pool gets about 8-9 hours of direct sunlight daily. I use only liquid chlorine, don't have a SWCG and my CYA is 30-40.

Yes! That's the same for me! I've had our pool since March, and see the same thing! There have been a few people who have said it's impossible, but they live in the northern US.

So, I ended up doing daily two 1" trichlor tablets and shocking after I brush to get gunk out if the vinyl folds.

I loose about 3-4ppm per day in south Texas as well, now my cya is over 80 from using tabs during the liquid chlorine shortage even after a water change last week.
This means I am having to keep my daily FC around 8 to keep the algae at bay, but my water is Crystal otherwise, that and I installed a homeade fountain to raise PH and lower temp.

FC=4.4 at 7:00pm last bleach added previous day at 7pm
CC=0
PH 7.6
TA=100ppm
CYA=80

So now I can calculate my pool requires around 1/2 gal of bleach per day with this cya level. Helps you to also purchase enough bleach to get through the season.
