AQUA ONE AIR STONE 2.5CM (2PK)

Made from quality pumice stone, the Aqua One Air Stone is a simple way to increase oxygen levels as well creating a pleasing visual effect in your aquarium.

Once connected to an aquarium air pump, the stones will inject a fine spray of bubbles into your tank that increase dissolved oxygen levels in the water.

This is particularly beneficial to cold water species of fish (like goldfish) in the warmer months, when higher water temperatures lead to decreased oxygen levels.

Tropical species benefit all year round by having stable levels of oxygen in the water, with increased water circulation also providing health benefits.

Please remember that the air stones cannot be used on their own, and required an air pump and hose to operate.

It is also highly recommend to purchase a check valve (605006) as this will prevent water from syphoning back into your air pump should the power go out.
