400 cya

[PoolDoc]

How high am I going to run the Chlorine?

Depends on your actual CYA level. We won't know till you get the K2006.

Can I test it accurately with the CYA so high?

Yes, but I'll need to walk you through it, and you'll need a gallon of distilled water (water section at Walmart), and something like a stainless 1/4 cup measuring cup.

Do I still need to add the bleach with the chlorine reading over 5ppm?

You EITHER have to use higher chlorine (very dark yellow to orange) OR you have to use an algaecide.

My Taylor test kit came. What tests do I now run and how? CYA?? Thanks kevin

[PoolDoc]

Yes, please, and pH and chlorine.

Given that you already suspect a CYA > 200 ppm, may I suggest you test a diluted sample, like this:

1. Collect 1/2 cup of pool water
2. Add 1/2 cup of tap water & mix
3. Fill your CYA sample bottle to the first line.
4. Add your CYA reagent & mix
5. Wait 60 seconds, and mix again
6. Wait 30 seconds
7. Hold the sample tube at waste height, outside in good light but not direct sun
8. Add CYA mix to the tube until the dot at the bottom disappears.
9. Read the scale on the side of the tube, corresponding to the sample level inside the tube.
10. Multiply this reading x2 -- that is your CYA result in ppm.

Ben, Is there a place on the forum that simplifies the ph and cl tests with the taylor kit? I'm trying to understand the directions and its hurting my brain. Or do I just need to try harder? Thanks Kevin

See if this helps. If you need more information, let us know.

Performed the following tests:

1. ph is a little less than 7. Will go to find borax and wait for instructions.

2. Free chlorine test does not turn pink when powder is added. (indicating no free ch?) Will get gallons of bleach. I did not continue on to combined ch test.

3. CYA test per Ben's directions: 7 ml of half diluted pool water. 7ml of reagent. Added this to tube until dot disappears and the level only comes up to about a third of the way to the 100 mark. Multiply this by 2 to get 60. Can I say YIPPIE!!! ??? Maybe my CYA isn't so high after all?? What's up with my pool supply store who gave me a 400 CYA reading? Thanks Kevin

What's up with my pool supply store who gave me a 400 CYA reading?

Once people get their K-2006, more often then not they discover that their pool store's testing was bogus. What people don't realize is that pool stores have a NEGATIVE incentive to provide accurate testing, because ACCURATE testing reduces chemical sales!

=> With at 36K pool at pH less than 7.0, start with 2 boxes (added slowly to the skimmer, pump on), wait 4 hours, and retest.

=> You really, really want to avoid zero chlorine.
