Poly-Mart 500 Gallon Vertical Liquid Storage Tank 1.5 SG

Poly-Mart offers a line of Liquid Storage Tanks with a Specific Gravity of 1.5 & 1.9.  Specific Gravity is the ratio of the density of a substance to the density of a reference substance.  The reference substance is water for liquids.  A 1.5 specific gravity means you can store liquid 1.5 times as dense as water.  Those substances with a specific gravity of greater than 1 will sink in water, while a substance with a specific gravity of less than 1 will float in water.  Our line of Plastic Storage Tanks is generally used for the bulk Salt Water Storage, Liquid Fertilizer Storage, Farm & Agriculture Chemicals Storage, Industrial Chemical Storage, Reverse Osmosis System Storage, Brine Storage, Soap Storage, Cleaning Agent Storage, Waste Vegetable Oil Storage & Frac Water Storage.  Our Liquid Storage Tanks are a translucent white color for ease in level viewing and are also equipped with gallon markers.  Our Plastic Storage Tanks come with vented slosh proof lids, inlet bulk head fitting, outlet bulkhead fitting & outlet plug.  These tanks are available in our Natural White color as well as Black.
