Just curious, since CYA testing is based on turbidity. Can a CYA level of 100+ prevent from having crystal clear water, even if all other tests are normal?
Can high CYA be a factor for cloudy water?

Because of all the other problems it causes, you could induce that CYA could cause cloudy water but I doubt you would ever see any affect from the CYA alone.
Now, If you added a couple of 50 gallon barrels of CYA reagent to your pool, you will have instant turbidity. Without the reagent, high CYA should have little DIRECT cloudiness in your pool.

If CYA can only be lowered by removing water, does normal evaporation count? I can lose a few inches in FL easily on hot/humid weeks.
No, CYA does not evaporate. Water evaporates and is replaced, leaving the CYA level the same. Sometimes it goes away during the winter, sometimes it doesn't. Splashout and backwashing (if you backwash) will lower CYA.
With high CYA levels it becomes more difficult to keep the water sparkling, but it is still possible.

But after high evaporation weeks, I end up pumping in lots of tap water. Wouldn't that have a dilution effect with CYA (over a long period of time of course)?
Nope, As Jason said, the CYA doesn't evaporate.
Theoretically, your entire pool could evaporate and you'd have X pounds of CYA lying on the bottom of your pool floor.
(plus some other solubles and maybe a catfish or two :lol: )

What about the tap water I put in to replace the evaporation, any dilution effects to the existing CYA?
Look at it this way:
Start) 10,000 gallons of water and 12 lbs of CYA
1,000 gallons evaporate
Middle) 9,000 gallons of water and 12 lbs of CYA
1,000 gallons of tap water added
End) 10,000 gallons of water and 12 lbs of CYA
The key point is that when water evaporates the CYA stays in the pool. CYA doesn't evaporate. The water comes and goes, the CYA stays.
You start and end with the same amount of CYA. In the middle, when the pool is low, you have more ppm of CYA than at the start or the end (but usually not enough different for it to be obvious in testing).
