This pump requires no regular internal maintenance during its life. The rest of the air system should be periodically checked and cleaned.

• Air lines should be carefully inspected whenever standard aquarium maintenance is performed.
• Adjust, or if required, replace all sections which are pinched, kinked, or otherwise damaged.
• All attached air driven aquarium ornaments should be regularly maintained.
• Algae growths should be removed from moving parts.
• Ornament surfaces should be kept as clean as possible.
• Internal air tubes should be cleaned.

Air stones should be kept clean and free of debris or algae build up. The ideal situation is to replace them every month, alternating with an extra set which has been dried over that period and cleaned before being placed in the aquarium.

Two complete sets of air stones, alternately changed each month, will extend the life on the air stones and help keep back pressure to a minimum.
