Pool Water Turned Green After Adding Shock

[tdoss]

Thanks for updating my pool chart. I read the "getting started thread" and thought I should make the chart first, then post. I tried entering that before I started a thread and I guess it doesn't work that way.

I have no idea what was in that shock. I don't know why my CYA is so high...I've NEVER added cyanuric acid (unless it was through shock inadvertently). I bought my first bottle of cyanuric acid granules from Home Depot two days ago just in case I need it.

I tested my CYA again using my K-2006 kit. I bought some distilled water but I didn't understand how I should test it by multiplying drops by 3. The test kit I have says to mix 7ml of pool water...add one of the ingredients...I think r0013 until it hits 14ml mark.

Then...mix that up for 30 seconds. Then add that to the smaller test tube until you can't see the little black dot at the bottom. I did it twice and both times it disappeared before it hit the 100 mark on the little tube. As the tube fills up...the number goes down...to something like 30. Am I using the right tube? Am I doing this test properly? I have no idea how I'd use distilled water and count any drops. Oh wait...would I mix as you suggested...then dropped drip by drip until spot disappears and then multiply by 3?

The bleach I'm using is L.A.'s Totally Awesome Bleach...but I just noticed that my jugs have 96oz. So...I'll increase it to make up that difference.

Here's the new test results after 4 gallons of bleach per day and 1 full gallon of muriatic acid. I haven't had the filter on 24hrs but I've increased it tremendously...to 12-14hrs.

4.6ppm FC
.4ppm CC
7.5 PH = with the drop test it says 2 drops to get it to 7.2PH
80ppm Alkalinity
360 Calcium Hardness
100+ ppm CYA (I don't know how much but it doesn't get to 100 before the spot disappears...if it's incrementally like it is at 80, 90 and 100...I'd estimate somewhere like 130ppm.

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

I got home really late last night so I added chlorine and muriatic acid and went to bed before checking or responding to this thread so this is what I did and where we're at right now:

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).

I added half a gallon of Muriatic Acid.

I tested today and this is what I got:

13.6 ppm FC (tripling the previous test from two days ago). Also...I still used the 25ml test just so we're comparing apples to apples. Next test, I'll gladly switch to 10ml so I can save as much of the test drops as I can.

0 CC (Is this right? I even added some extra drops to try to get it to turn pink and it wouldn't...did I do something wrong?)

7.5 PH (this didn't move even with the half gallon more of Muriatic acid so I added the rest of the gallon after my tests today).

I broke out my old test kit using OTO drops and it looks like the shade of yellow for chlorine is darker than the highest mark of 5. I also tested the PH using it's Phenol Red drops and it showed the PH around 7.2. I trusted my new, more advanced kit and added the rest of the Muriatic acid like I said above.


Now...for the CYA testing...I have to start by apologizing...I'm not sure why I'm having so much trouble understanding and following directions on this but here are my current questions involving the distilled water (I made sure I have distilled...one gallon is $0.88 at Walmart).

At step 5 you say to collect 14ml of the test sample from mix in step #4. I question this because the test kit I have says to take 7ml test and then add R0013 until you hit 14ml mark. However you're saying to collect 14ml of the test sample and then add 14ml of the R0013. I guess it's all the same proportions but my kit won't hold that much so I'm assuming I'm using another clean container to hold the new mixture of 14ml of sample and 14ml of R0013. Please confirm.

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?

Would it help if I took a picture of the little tube I'm talking about? This is a link to a picture of a tube...not mine but one that seems to demonstrate what I'm talking about. The more I add...the lower the number:

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%

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.

[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.

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.
