Self-aerating container

摘要

A simple self-aerating container for small marine life which requires no power. The aeration rate is easily adjusted continuously and remains constant once set. At low flow rates, the container can be aerated over night, and the high flow rates can be used when there are a larger number of small marine life in the container, or when it is desirable to have them very active. The aerator consists of a tank with a hand pump, a simple pressure regulator, and a unique mass (air) flow regulator. The tank is also equipped with a spring loaded safety valve and a valve for filling the tank at a service station.
