Pool Water Turned Green After Adding Shock

[PoolDoc]

I added six (6) more jugs (96oz each) of bleach. It does not say the percentage anywhere on this bottle (which is one reason why I listed what type I was using just in case I'm not using the correct type).

Was this Walmart bleach? Bleach with no listed % is probably VERY low. You might want to check the label again -- I'm not sure if genuine bleach can be sold without a %; Walmart Great Value bleach is listed at 6%

I'm still confused by step #9. In my test kit, it says to mix sample and R0013 together for 30 seconds and then pour into the small tube until the dot just disappears. I can absolutely drop, drip by drip, counting and then multiplying however the math seems off to me. The reason being...in my little tube...the less mixture I use to make the dot disappear, the higher the number line on the side of the tube. The more of the solution I add...the lower the number. It starts at 100 and the lines steadily go UP the tube until it reaches 30 near the top.

If I add drops...counting and then multiplying by 3...then the more I add...obviously, the higher my result will be. That seems completely converse to what my kit does...or am I completely misunderstanding this kit?

The CYA test is NOT a drop count!

Then what am I multiplying by 3? The video says to simply read the water level on the tube. So...if the water level ends up at the 100 line when the dot disappears, do I still multiply by 3 and have 300 as my result?

Also...you didn't clarify on the 7ml versus 14ml question above. The video and my instructions say to go to 7ml line with sample and add R0013 till you reach 14ml line. You're saying to use 14ml sample and 14ml of R0013. I just want to make sure. And to do that...I'll need to use another container to dump the 14ml of sample into and then the subsequent 14ml of R0013 into to mix.

You don't multiply by 3 on the CYA test. You read the number on the side of the tube when you get to the point where you can no longer see the black dot. 100 is the limitation on the test. Did the dot disappear at 100 or could you still see it?

Use the 7ml sample of pool water and then add 7ml of R0013.

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.

I did that and the dot disappeared before it got to the 100 line...as I described earlier in the thread.

I'm looking for clarification on the distilled water + CYA test that pooldoc describes above.

[PoolDoc]

I don't have a K2006 here -- is the sample bottle 7 ml + 7 ml, instead of 14 ml + 14 ml? If so, it's indeed a typo.

But the point is you dilute POOL water 1:2 with DISTILLED water, mix that, and test the mix, as if it was pool water.

THEN, after testing, you multiply the test result by 3.

I hope this is clear.

Two other points:

1. The CYA test is NOT a drop count test; you simply add sample till the dot disappears, and then read the result on the side of the container.
2. Other dilutions are possible. If you dilute 1:1 (half pool water, half distilled) you multiply by 2; if you dilute 1:3 (1/4 pool water; 3/4 distilled, you multiply by 4.

[Charlie_R]

K2006 is indeed 7mL + 7mL.

It makes perfect sense now. You're diluting it so I can get the reading somewhere on my test tube between 30 and 100 because mine is somewhere beyond 100. I like it...very smart fix. I'll do that and report back.

Sidenote: I replied to the email but never heard back...is there any way I qualify for an upgrade so I can reply without waiting for someone to approve?

[tdoss]

OK...this is where I'm at:

22ppm FC
.5 - 1ppm CC
7.2 PH

145-150 CYA (the test described above by pooldoc gave me a result that just passed the 50 line, going towards 40...so multiplying by 3...I'm very close to 150).

My pool is still incredibly green. I've never seen it like this. It doesn't appear to be sticking to the walls much but the water is so incredibly green that I can't see the bottom and I just can't tell if it's getting any better yet. I'm sure at some point...it will tip over a certain peak and all the green will be destroyed.

What should I focus on now with all of the numbers I've provided?
