Fish tanks made of polyethylene can be a great tool in the management of fish. This is because these tanks are robust and come in the form of round structure with a flat bottom that sits on a stand made from heavy metal. They can be used for aesthetic purposes such as displaying fish, or to raise or quarantine them.
Poly Holding Tank Characteristics
The majority of polyethylene holding tanks are nestable, meaning multiple units can fit within one another which significantly reduce shipping costs. While some models have a flat bottom, others have a bottom which is cone shaped. Cone style holding tanks are outstanding for fish rearing but will need a stand to support them. They can hold 1500 gallons or more, and will be blue in color.
For pond fish, these tanks can be used as a temporary domicile. For instance, fish can be removed from the pond and placed in such a tank while the pond is being cleaned or maintained. Fish that become ill can be separated from the other fish and placed in the tank as a form of quarantine, and these tanks can also be used for fish farming.
Poly Holding Tank Advantages
Holding tanks which utilize a cone bottom offers self-cleaning capability, as well as a structure which is 20 degree, meaning that solids will be forced to the tanks bottom which allows for ongoing cleaning. These tanks are exceptionally durable and because they are self-supporting can be utilized for both above ground and underground applications.
When it comes to raising fish round tanks have increased greatly in popularity. The reason for this is because these tanks use a centralized drain with a floor that has a moderate slope. This combined with the inlet piping allows the tank to make use of both centrifugal and gravitational force to maintain sanitation. The water in such tanks will flow in a manner which is circular and will move solids to a centralized drain, where they will then pipe, separate and either be disposed or reused. A tank with an efficient inlet system will contain water that is rich in oxygen and which provides proper current while distributing the water in an even manner.
Space utilization in the newest holding tanks has been greatly improved. As a result, a greater production of fish can occur for each unit of flowing water. In fact, the direction of the flow of water may be reversed every so often, which will balance the growth of fish by rearranging the order in which they feed. Because the bottom of such tanks no longer need to be cleared or sediment, the cost of labor and stress on fish is lowered. The fish excrement and organic debris will entire the pipe, where the solids can be efficiently separated and disposed of, using either a swirl separator or micro filter screen.
