13cm Air Stone

Cylinder Air stones create a wall of air bubbles to decorate, aerate and improve circulation in your aquarium or pond.

To install, connect to standard (4/6mm) silicone or plastic air line from the air pump and lay anywhere in the aquarium or pond.

The stone can be hidden from view using rocks, plants or other decor etc.

Recommended for use with Betta Airline Tubing, made from either silicone or plastic.

Description

The round cylindrical-shaped ‘stone’ is made from sand which helps to weigh it down in the water and give it a high surface area to release bubbles efficiently.
8cm and 13cm air stones are supplied in outers of 12, to be sold individually.
22cm are supplied in singles.
Suitable for use in aquariums or ponds.
