## Description

From the manufacturer

Review: Didn’t know I needed it! - My orb had no bubbles at all. While looking for reasons as to why it might be and knowing it wasn’t the pump at fault, I read that someone replaced the air stone. Took out the old one, put the new one and I have never seen bubbles like it. It’s the first time time I have done this and I have had my tank for years so it probably needs replacing more frequently. Simple little thing that has already made a huge difference. Cheap at the price and came next day as per prime. Definitely recommend. Cheaper than a pump.
Review: Bubbles - Really good does the job fine. Good price.

## Features

- Essential Aeration Component for biOrb Tanks: The biOrb Air Stone sits beneath the filter cartridge at the base of your aquarium, producing a fine, steady stream of air bubbles for consistent oxygen circulation and a healthier aquatic environment.
- Supports Efficient Oxygen Exchange: By regulating the airflow from your aquarium pump, this aeration stone ensures optimal surface movement - helping oxygenate the water and improve conditions for fish, plants and beneficial bacteria.
- Compact, Safe & Non-Toxic Design: Measuring 3.5 x 1 cm, this solid mineral stone is completely inert - it won’t affect pH or water quality. It’s safe for all fish and ideal for both freshwater and saltwater biOrb setups.
- Easy To Install & Replace: No tools required - simply remove your biOrb filter cartridge, swap out the air stone, and reattach. We recommend replacing every 3 months to maintain consistent airflow and system efficiency.
- Creates Calming Bubble Display: As well as supporting aquarium health, the air stone’s gentle bubble effect enhances your tank’s look and feel - ideal for biOrb owners who value visual tranquillity and fish-friendly design.

## 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.
