Cloudy water is like the CYA test kit. You look in and you cant see the bottom.

The first thing to dissapear is the drain at the bottom of the deep end.

Then the whole deep end and you can only make out the liner in the shallow.

Then if it gets really bad, you start counting how many steps you can see.

On the path to recovery from "cloudy water" you get excited as new bottom features emerge.

You have pollen or chemical debris - you will know cloudy water when it hits - and you will read this website like never before.
