Frequently Asked Questions

Q: What does the Aquapro Air Diffuser Atomizer Stone do for my aquarium?

A: The Aquapro Air Diffuser Atomizer Stone connects to your aquarium air pump and disperses air as ultra-fine micro-bubbles throughout the water. This increases the dissolved oxygen level in the tank, promotes healthy water circulation, and creates an attractive visual effect — all essential for the wellbeing of fish, shrimp, and aquatic plants.

Q: What is the check valve used for, and do I need it?

A: The included check valve is a one-way valve that sits between your air pump and the diffuser stone. It prevents water from traveling back up the airline tubing into your air pump if the pump stops or loses power — protecting your equipment from water damage. It is strongly recommended to always use a check valve with any aquarium air pump setup.

Q: What tank size is this diffuser suitable for?

A: This diffuser is sized as Medium (M) and is designed for aquariums up to 40cm in length, making it ideal for nano tanks, desktop aquariums, small fish or shrimp tanks, and planted aquariums. For larger tanks, multiple units can be used in combination.

Q: Is this diffuser easy to install?

A: Yes — installation is straightforward. Simply attach one end of your standard air pump tubing to the air pump outlet, thread the check valve onto the line (ensuring the flow arrow points toward the diffuser), and connect the other end to the diffuser stone. Place the stone in your tank and you're ready to go — no special tools required.
