Aeration for Fisheries “Unique Pipe”
Unique Pipe is installed underwater. When air is sent, tiny bubbles will be generated from the hose to provide abundant oxygen to live fish. It is possible to run the tube in a curved manner making it very flexible and easy to set up. It is ideal for transporting live fish, preserves, large water tanks and fish farms.
1. Because the bubbles are very fine, the amount of dissolved oxygen is very large.
2. It can be cut with a cutter and it is possible to run the tube in a curved manner making hose laying and set up very easy.
3. You can arrange the tube as you like to fit the size and environment of the water tank.
4. There are 4 types of Unique Tubes. 2 types for air, 1 type for oxygen and 1 for ozone. (The material for the ozone tube is different.)
5. Because it is made of special synthetic rubber, it is extremely durable.
