## Overview

The biOrb Airstone is a compact, efficient diffuser designed to enhance oxygenation in biOrb aquariums by breaking air into fine bubbles while reducing pump noise. It fits neatly under the filter cartridge and requires periodic replacement every few months to maintain peak performance, ensuring a healthy, vibrant environment for your aquatic life.

## Description

The biOrb Airstone fits in the base of the biOrb underneath the filter cartridge. It breaks up the flow of air into the aquarium, splitting it into a mass of fine bubbles. It also reduces noise from the air pump. Over time the tiny pores in the air stone can become blocked by dirt and limescale preventing air from getting through properly. Depending on your local water supply and the conditions in your biOrb an air stone can last anywhere from 3 months to 3 years. Changing the air stone from time to time is advisable.

## Questions & Answers

For further assistance, please contact our customer service team at 888-755-5646, Monday through Friday, 8am - 5pm, EST. We hope this helps. Best Regards, Your biOrb Aquatic Specialist, Jennifer.

**Q: Is this something I just drop in the hole the bubbles come out of?**
A: Hello. The biOrb airstone sits in the hole inside the filter housing. You would need to remove the bubble tube and filter to access the airstone. We hope this helps. Your biOrb Specialist, Natalie.

**Q: Can you use this on a regular undergravel filter attachment**
A: no. the hole to attach it is bigger than the average air pump attachment.

**Q: Why would someone need or use an air stone?**
A: To add air to the water, it helps circulate the water and provides air for the fish. I have one in the bottom of the filter pack in my BiOrb tank, one came with the tank and I replace as needed.
