I have a huge glass lined storage tank for sale. It is I believe 800 gallon capacity with 1/4 inch steel and 2 inches of glass lining. Water only has been in this tank but I understand with the glass lining it can be used with caustic solutions also. The price is $800.00 and anyone familiar with this type of tank realizes that is a steal. You haul. You can email me or call 724-872-5389.
