BIOSCAPE TROPIC MINERAL AIRSTONES
The Bioscape mineral stone is ideal for adding accents in any aquarium. The air stone diffuses air, creating water movement. The air stone also increases surface agitation, accelerates oxygen replenishment and helps release carbon dioxide build-up. Simply connect the air stone to your airline tubing and place it in the desired location.
An air pump, air tubing & check valve are required to operate, these are not included.
