If it is starting and stopping so to speak, make sure you do not have sand in the aquarium that could be causing the issue. When sand is in use, you need to place filter floss inside the strainer or put an accessory sponge over the strainer.
Another thing that will cause filters to turn on and off are air bubbles. If you have an air stone in the tank, try turning it off and testing the filter.
Take the filter apart, removing the intake tube, impeller housing, and impeller. Clean it thoroughly, especially the impeller, and the bottom of the filter box, where the impeller resides in the motor well. You may have some sludge or other build up causing an issue. In the event of hard water or marine water, use distilled white vinegar to clean everything and rinse well.
Last, make sure it is plugged into a power strip and not an outlet in case of voltage issues, if this is an older home.
A filter's purpose is not to keep the fish alive, but to reduce the maintenance of the tank. So until you determine what the issue is with the filter, step up on the water changes. Vacuum and do 10% at a time, every couple of days, if the filter continues to have an issue. Also, call us directly so we may assist you. 1-800-322-1266.
