Does this fit over air tube with bioorb sculpture too over air tube?

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.

Is this something I just drop in the hole the bubbles come out of?

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.

Can you use this on a regular undergravel filter attachment

no. the hole to attach it is bigger than the average air pump attachment.

Why would someone need or use an air stone?

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.
