I am making room in my service garage for some shelving upgrades. I have this 250 gallon caged water mixing tub that I used to mix fresh saltwater. I used to mix 200 gallons at a time. This tub originally held barley malt and has had nothing in it but saltwater since I have used it. I've used it for several years and as you can see in the pics it has insulation around it for the winter. Tub has screw on lid that seals via o-ring and lid is drilled to accommodate an RODI line to fill. It has been drilled in two places; on top for electrical cords and on the drain side for circulation plumbing. Easy to clean out with a power-washer.
FREE to anyone that could use it. Can be made into a rock curing vessel if needed. You haul out.
