Superior Biological FiltrationThe patented biological grid has a large surface area to support more of the beneficial bacteria that eliminates ammonia and nitrates. A second wet/dry grid provides further biological filtration and oxygenation as the water returns to the aquarium. Internal Pump DesignSince the filter pump is submersed in the aquarium, there is no need for priming at setup or when restarting the filter after cleaning or power interruptions. An internal pump also allows for virtually silent operation, continuous flow raters, less chance for leaks, and a much thinner profile.
