Airstones may become clogged due to algae growth,mineral deposits, and/or organic
deposits.The occurrence of these factors varies depending on the amount of light
hitting the tank, the hardness of the local water supply, and general maintenance
practices.When airstones become clogged, they must be changed...and all of them
must be changed at the same time.
To change airstones, follow the steps below.
1. With the system pump running, remove the Carbon
Box Lid. Each Air Stack contains a white rigid tube
attached to a length of flexible connector tubing.
Disconnect the tubes and tubing in each Air Stack and
remove the white rigid tubes with airstones attached.
2. Test for clogs by blowing through each white rigid tube.Air should pass easily
through the stones. If you find yourself blowing too hard, the airstones are clogged
and need to be replaced.
3. Pull the clogged airstones off the “Y” Connector
at the end of each rigid white tube.
NOTE: Replacement “Y” connectors
(Part #C1515) can be ordered by calling the
24-Hour Marineland Hotline at 1-800-322-1266.
4. Place the new airstones on each open end
of each “Y” connector.
NOTE: We recommend you use only Marineland
airstones. They last longer and provide more
bubbles for aeration.
5. With a rubber band, wrap each pair
of airstones together.
