I found pulverized limestone at my local Home Depot in 50 # bags but they didn't have enough.

Also found North American Gypsum in Dallas , Tx. but have not called them as yet . Don't no if they will sell to me direct or what qty. I would have to buy .

Doe's anyone know how much it would take for a 2 acre pond appx. 5 to 6 ft. avg. depth.

I'm almost positive my problem is suspended clay . I can fill a jar with the pond water and within a short time particles begin setteling on the bottom of the jar .
