Tom Aquatics Oxygen Stone generates oxygen when immersed in water. It keeps producing oxygen for about a month, enabling you to safely keep your fish in a small tank without the use of an air pump.

Oxygen helps bacteria speed the decomposition of fish and plant waste by means of oxidization, and helps clean the water. Suitable for both fresh and marine aquariums.
