Can't hold FC

[PoolDoc]

+ 2 gallons of 6% bleach will add 2 ppm of chlorine to a 30,000 gallon pool.
+ Given your situation, I would start with a 10 gallon dose each evening. If your chlorine levels (OTO after 1 minute) the following evening is 3 ppm or less, repeat. If it's more than 3 ppm, use 5 gallons. If it's orange in color, skip it.

Thanks, I will start tonight. I did get an ammonia test kit. The reading was .50 ppm. What reading do i want to get to?
Also, I have ordered a Taylor test kit, but it will not be here until July 15th.

Once you get to a zero ammonia level, you will likely no longer lose chlorine overnight.

By the way, many strips are not very accurate. You might want to test your tap water -- which should be zero ammonia -- just to make sure the strips you got can actually tell the difference between 0.0 and 0.5 ppm.

But, otherwise, the instructions I gave you earlier still hold.

Slight correction: 1 gallon of bleach adds 2ppm to 30,000 gallons, not 2 gallons, which would add 4ppm. Just a typo.

HOWEVER, as recommended, the 10 gallons adds 20ppm of chlorine to 30,000 gallons and that is EXACTLY how much you need to shock your pool with its high CYA level of 94.

Thanks for the correction. Good progress after two nights of 10 gallons. After the first night, i was able to hold between .65 and 1.3 for 24 hrs.according to my liquid test kit. This morning (8 hrs later) I am testing 10 plus (Taylor Kit not arrived yet).

Question on the ammonia test. First, I purchased the liquid test kit from Pet Smart. It has a excellent color chart with a white background that allows you to get a true color comparison. My question is should I use the chart for fresh water or salt water.
I read somewhere that bleach does add salt. If it is freah water, I have gone from .50 to .25. If it is salt water, I am .0

I feel good about the progress. I am sure my recycle guy will wonder what I am doing with all the bleach.

[PoolDoc]

Your use of bleach wouldn't be enough to make the water "salt".

Regarding bleach bottles, I've seem some pictures of them stacked WAY high when folks had to clean up a swamp on a large pool.

In a few places you can buy fresh industrial bleach (10 - 15%) in 3 - 5 gallon containers.

For every 10 ppm Free Chlorine (FC) added by ANY source of chlorine, the chlorine when consumed/used will result in 8 ppm salt. For bleach or chlorinating liquid, they add an additional 8 ppm salt upon addition. With 2 ppm FC per day chlorine usage, this means that bleach or chlorinating liquid will add around 100 ppm salt per month if there were no water dilution, so not very much given that salt water chlorine generator pools are 3000 ppm.
