Very Interesting Problem

[gonefishin]

I do not recall seeing high CYA values and cloudy water being closely related on this forum. Not saying they are not, I simply don't recall it.

I DO frequently see cloudy water and CC associated, however.

This "best guess CYA chart seems to be a handy chart. Trouble with high CYA seems to be that it demands higher minimum chlorine levels be maintained to sanitize the water.
