Add a magnum with a pleated micro cartiage to the set up or a 9 3/4" pleated
canister unit from a hardware store etc. This by itself is effective as
well. Your bulb may be old and ineffective/too much flow through the unit
(but I doubt that is the case unless your putting over 250-300Gal/hr).

The new tetra 5 watt model was super for a 50 gallon tank at about 150GPH
and nothing else added(no micron cartiage).
