The Chem-Tainer 300 Gallon HDPE Vertical Liquid Storage Tank (SKU TC4560IA) is a 300 gallon vertical storage tank molded in white polyethylene, standing 60 inches tall on a 45 by 45 inch footprint. It carries a 1.9 specific gravity rating, and that number is the headline here. The 1.9 SG shell is a heavier-walled build than a standard 1.0 or 1.5 SG water vertical of the same size, which is exactly what lets it handle denser liquids without overloading the wall.
Will it work for your liquid?
Filled with water, this tank carries about 2,502 pounds of contents. Because the shell is rated to 1.9 specific gravity, it is engineered to hold up to roughly 4,754 pounds of contents at maximum rated density. In plain terms, you can run liquids heavier than water in it - up to 1.9 times the weight of water at the same fill level - without exceeding the wall's design load. For straight water storage that leaves a wide safety margin; for denser liquids, the 1.9 rating is what keeps you inside spec. Run the numbers with the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 300 gallon capacity and the 45 by 45 inch footprint fit your pad and your fill volume before you order.
The mistake to avoid
The number that trips people up on this tank is the specific gravity. Do not assume any 300 gallon vertical is interchangeable - the weight your liquid puts on the wall is what matters, not just the gallon count. The "IA" suffix on TC4560IA denotes the 1.9 SG heavy-wall variant; a 1.5 SG version of the same footprint exists as a separate SKU, so cross-check the suffix before you buy a cheaper-looking match. And the HDPE shell is only half the compatibility question: confirm fitting, gasket, and outlet material compatibility with your specific liquid before service, because those wetted components - not just the polyethylene - determine chemical suitability.

For the methodology behind cross-shopping verticals across brands, the Snyder vs Norwesco vs Chem-Tainer comparison (a larger 2000 gallon tank, but the same decision logic applies) and the 300 gallon vertical buyer's guide (a taller 35 by 79 footprint, useful for seeing how footprint changes the fit) walk through how capacity, footprint, and specific gravity should drive the decision.
