Round Flat Bottom Tank

The 300 gallon round flat bottom tank is a versatile, space-efficient solution for a wide range of water-handling applications, including aquaculture production, koi display setups, filtration systems, and general-purpose holding. Designed with a round profile and a flat bottom, this style of tank is commonly chosen when you want stable placement on a level surface and straightforward plumbing options using bulkhead fittings.

This tank is frequently used in facilities and backyards alike because it balances capacity with a manageable footprint, making it practical for staging livestock, isolating fish, or building out a recirculating system. If you’re planning a koi viewing or sales display, the round shape supports smooth circulation patterns and helps reduce “dead spots” compared with cornered containers. For filtration and settling use, the same round geometry can simplify internal flow management when paired with appropriately placed inlets and outlets.

Key features
