Pool Water Turned Green After Adding Shock

[PoolDoc]

You should be able to enter the chart, after you register, but before you post. Actually, you can enter data before you register, but I have to dump it, because without a user name I can't match it up.

With a green pool and a CYA>100 ppm, you need to add 30 ppm FC tonight (30/PF9 = 3lbs chlorine gas equiv) which is 6 *gallons* of 6% (check the %!) bleach or 8 96oz jugs.

Test your chlorine the following morning, and add bleach to return levels to 30 ppm (3.5 ppm per 96oz jug of 6%)

When you test your chlorine, use the 10 ml sample size instead of the 25 ml sample -- saves reagent, and you almost never need to know chlorine levels to the nearest 0.2 ppm.

Distilled water + CYA test:

1. Get a 1 gallon jug of distilled -- not bottled, not spring, not natural, but DISTILLED -- water.
2. Collect a sample of pool water.
3. Pour 2/3 of a cup of DISTILLED water into a CLEAN container.
4. Pour 1/3 of POOL water into the same container; mix.
5. Collect your 14 ml of CYA test sample from the MIX in #4
6. Add 14 ml of melamine (R0013) reagent to the test bottle. Mix
7. Wait 15 seconds; mix again.
8. Wait 45 seconds; then test.
9. Multiply results x 3
