As we intake oxygen to live, Fish also need oxygen in the
water. Normally at sea or in river water will be continuously
running, "Running water Automatically generate lot of oxygen.
But at Aquarium, water will be stable. So aquarium water
losses its oxygen.
To Create Oxygen in water we need an equipment Called as
Air pump will create bubbles is water which creates Oxygen.
Oxygen motor also keeps the aquarium in circulation. So the
water will not get spoiled.
Air stone are used to diffuse the oxygen bubbles. An air
stones comes under different design and size. Models:
Round, Stick, Star etc.
Air tube will create a link between Air Pump and Air Stone.
Air tube also helps in covering the distance between tube
Oxygen motor and Fish tank.
Air controller can be placed in oxygen tube. It helps to control the flow
of oxygen into water.
