Pool Water Turned Green After Adding Shock

[Charlie_R]

He was asking about the diluted as suggested by Ben, on the CYA test. His normal test is >100.

From PoolDoc's post above:

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

As I understand it, Ben did a typo in the instructions. Should be 7mL diluted pool water, then R-0013 to 14mL mark, mix, let stand 30sec, etc. Then yes, multiply what you see on the side of the tube by 3.

Ah...this makes sense...I believe he's trying to dilute the mixture so that I can get some sort of a reading on the tube from 100 to 30...then I'd multiply that result by 3 to get my real number which I presume will be somewhere around 130-150.

I'll use the 7ml distilled + sample mixture plus 7ml of R0013 to get to 14ml and will multiply the result by 3 and will report back.

Also, all week...I've filled the floating tablet things with bleach tablets and let them float.

I added another six (6) 96oz jugs of that bleach I'm using. It's L.A.'s Totally Awesome Bleach. It says it contains Sodium Hypochlorite but does not tell the percentage. I buy it at the .99 cent store. I've emailed the company to inquire about the percentage. Once it's all gone...I'll switch to Wal-Mart or somewhere that carries bleach with the percentage listed on the bottle/label.

I did a couple quick tests just now and this is where I'm at:

22ppm FC
.5 - 1ppm CC

Is that CC correct? I've been adding this bleach all week and the FC is rising as expected but I'm unfamiliar with CC and it appears to be lowering or almost non-existent.
