Pond Boss Forums GENERAL QUESTIONS Muddy water Gypsum Source in East Texas?

We were contacted about a muddy east Texas pond (near Dangerfield). They need about 3 tons of gypsum delivered and spread if you have the right equipment, otherwise we said we would help them spread it when we have time. One reputable source would not deliver unless 12 tons or more was ordered. Any recommendations on vendors that sell it near Longview or Athens, TX would be appreciated. As always thank you Pond Boss Forum for the help!
