## Overview

The biOrb Air Stone is a precision-engineered accessory that breaks down pump airflow into fine bubbles, enhancing oxygen distribution in your biOrb aquarium. Designed for universal compatibility and easy replacement every 3 months, it ensures consistent water clarity and fish health in both freshwater and saltwater setups.

## Description

Product Description biOrb Air stone fits underneath the filter cartridge. It breaks up the flow of air into the aquarium, splitting it into a mass of fine bubble. Over time the tiny pores in the air stone can become blocked by dirt and lime scale 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 a year. Set Contains: 1 x Air Stone

## Features

- Practical and suitable accessory for your biOrb aquarium
- Simply replace the air stone approximately every 3 months
- Generates small air bubbles from the air flow of the pump and uniformly regulates the flow of the air bubbles
- Suitable for all biOrbs

## Questions & Answers

**Q: Does this fit over air tube with bioorb sculpture too over air tube?**
A: The biOrb airstone sits in the bottom base of the filter assembly. The filter and bubble tube sit over the air stone.  We hope this helps. 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.
