PondMax 50mm Sphere Air Stone

CLICK HERE TO READ OUR ARTICLE ON AERATION

Air Stones circulate aquarium and pond water, generating oxygen whilst providing environmental enrichment.

NOTE: Airstones need to be connected to an Air Pump in order to provide aeration. Air Pumps are sold separately!

Ensure a check valve is in place. This will stop any water from siphoning out of your aquarium or pond if the pump fails. Try to keep the Air Stone level. This will ensure bubbles along the entire length of the stone. If the air Stone stops working correctly remove it from the aquarium and clean in warm water, or replace it. Check the operation of your air pump as the diaphragms or flapper valves inside the pump may have deteriorated.

Direction: Rinse the air stone gently in warm water to remove dust.
