This 337-gallon rectangular fiberglass sump tank manufactured by Hydro Composites is designed for Aquaculture and other applications. These tanks are fabricated using contact molds built in-house by our skilled staff. Thickness, color, and bottom shape can be altered depending on the application for the tank. If your application requires a size we do not currently manufacture, we can make a mold and produce tanks to your specifications. We have the ability to put your concept into CAD to ensure the design meets your satisfaction prior to construction. Hydro Composites manufactures all tanks using premium FDA approvable iso-resins, gel coat, and glass materials.
