TOM Oxygen Stone - 5 Pcs

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 Stone helps clean the water. Oxygen helps bacteria speed the decomposition of fish and plant waste by means of oxidization. 
  • Oxygen Stone is suitable for both fresh and marine water.
