Using salt level to estimate cya

[soundguy]

Hi All..

Here in south alabama, for the month of june, we are up to over 6" of rain.

To avoid using my cya test kit so much can I estimate the cya based on salt level?

For example:

The measured salt level is 3200 ppm ±200
The measured cya is 70 ±10

In a give amount of time I measure salt to be at 2800 ppm
That's a 12.5% reduction.

Can I assume the cya has reduced by the same ratio?

Are there more factors to consider that makes this more complex?

Thanks.

I got homework for you. Why don't YOU be the guinea pig and test that theory for yourself and the rest of us. Best time I can think of to "waste" a CYA test. There is no substitute for accurate testing.
