Hygger Blue Air Stone increases oxygen level in the water as well as adds beauty to your aquarium by producing a stream of tiny bubbles.
Constructed from nano material covered with plentys of miniature holes, once connected with air pump, this bubbler will create a great mount of tiny bubbles.
Suitable for aquarium, koi pond, hydroponic system, fish hatchery and aquaculture applications.

Directions:
Connect the air stone to the airline tubing and the airline tubing to the air pump. Place the air stone to the bottom of aquarium.

How to choose the right size for your tank?
How smaller and how much of the bubble depends on two factors:
1. Fish tank's water deepth
2. Air pump's output
We recommend water deepth under 17 inches, choose 2 inches air stone by using 3-4W air pump.
Water deepth range from 17~23 inches, choose 4 inches air stone, running 5W and up air pump.
If water deepth is over 23 inches, using a more powerful air pump. Otherwise, it might not produce bubbles.
Note:
1. You do need to soak this air stone in water for around 30 minutes before using it.
2. Clean the surface of air stone regularly in case clogged.
3. If air stone produce zero bubble, it means that the air pump is not power enough. Please replace stronger air pump in this case.
