AquaClear External Power Filter Manual

The AquaClear Foam, Carbon, and AMMO-RID inserts should be changed alternately in order to maintain continuous biological activity.

Never replace all filter media in any AquaClear filter at the same time.

Follow individual packaging instructions for proper replacement intervals. When rinsing an insert, it is best to rinse only in used aquarium water or lukewarm dechlorinated tap water to protect the bacterial population. This will ensure the least amount of disturbance to the biological filtration during standard filter maintenance. The filter inserts initially require several days to commence full mechanical filtering action. Bacterial cloudiness may occur during the first week of a new aquarium set-up. Biological balance of a new aquarium should occur within the fourth to sixth week of operation. Established aquariums will accomplish biological filter balance within the second or third week of operation.
