Perched Water Tables
With all my searching on perched water tables, I'm still unsure of a few things...
1) How can you identify a pwt in a container?
2) I know the pwt is said to disappear as the particle size reaches 1/8", so does that mean I could screen my turface with a 1/16" screen, then mix it with my growers sized gran-i-grit and have a mixture with no pwt? When screening turface over 1/8" screen I lose a lot of turface, so I'm hoping I can sick with screening over my regular 1/16" window screen and that the addition of grit will eliminate the pwt.
