Cya recommended 75

[jsikveland]

I tested my cya this morning with the Taylor k2006.
I entered into the tfp app at 50.
It is saying the recommended level is 75.
But everywhere else I read says 75 is high
Is a higher cya recommended because it’s a salt water pool?

By all means, read the material posted above, but as a general rule of thumb, I go with ~10x my FC amount for CYA. I keep FC around 8, so I go with CYA of 80. If my FC creeps up to 10 or so, I don’t raise CYA. 80 is as high as I’d go and will err on the low side since the test is so subjective.
