Answer
Hi Gordon;

Air is probably getting into the canister somehow during operation. Be sure the intake isn't near bubbles from the outlet water flow or from an airstone or anything. Check all the water hose connections to be sure they are snug. Also check the rubber O-ring under the lid. It may need to be replaced or may simply need lubrication. If you bought the filter as new there should be some silicon lubricant included with it. If you don't have the original manual, below is a link to one you can view and print if you like. It gives other suggestions for troubleshooting and maintenance as well;
