Can't Get Clear (Have PS233 Results)

[aswetich]

Ok,
One person says to keep the CL (Is this TC?) at 20 ppm and one says don't go below 3.5 FC. I am assuming they say the same thing so I will ask the question I have related to the bleach calculator. The bleach calculator has a ppm increase field but I don't know how to calculate what my existing ppm is. Can you tell me how to use my numbers above to figure out the current ppm so I can enter the ppm increase in the ppm calculator ?

Thanks

You don't calculate what your existing PPM is, you measure it with a test kit. Measure the FC with the DPD-FAS test. If you want to get to 20 ppm Cl, and your test results are 3.5, then 20 - 3.5 = 16.5. Put that number in the ppm increase field and hit calculate. You'll be shown how much bleach to add.

That is what I calculated but I assumed I did something wrong. My 32K pool will require 8 Gallons of 6% to get to 20 ppm. With the readings I displayed above does 8 gallons seem correct ? What number do I want to use to keep at 20 ppm ? FC, CC, or TC ?


Thanks
