The use of prefabricated glass-coated steel tank kits can significantly reduce installation costs.

Aquaculture Tanks

In aquaculture systems, there are a variety of fish farming tanks designed in different styles. Nowadays more fish farming tanks designed has been a marked shift towards circular aquariums. A properly designed circular tank with a central drain to keep the fish farming tank water clean. The circular storage tank has the advantage of natural self-cleaning. As the water swirls around the tank, the solids are pulled toward the center, the exit. Because of this property, they are often used in hatcheries, where solid loads (waste feed and dung) can be very high due to high feed rates and are also in the circulation system to remove solids as quickly as possible before they break down. Circular tanks can be built from almost any material, the most common being Glass-Fused-to -Steel tanks, which are strong enough to keep water from deformation, corrosion, abrasion, and non-toxic. Other advantages of the round container include: good mixing of water, easy oxidation; The fish has less contact with the wall and bottom of the tank because the wall and bottom are higher. Many species prefer the steady flow of water in a circular tank to other systems.

A circular tank aerated system can produce more pounds of fish with less feed, less water, and less pressure than a trench or pond of similar size. The use of prefabricated glass-coated steel tank kits can significantly reduce installation costs. The smooth tank surface further helps to eliminate disease vectors and skin abrasions, while providing a durable, economical tank.
