Our moisture trap funnel system which compliments most of our aquarium Super Feeders® is a patented flake food delivery method that we are describing herein for informational purposes only.

Our moisture trap funnel only comes with the ASF-1 Aquarium Super Feeder®. That very simple gadget is the key to keeping moisture away from our Super Feeders®, particularly when dispensing flake food. The funnel can be installed on a temporary or permanent basis, the latter being preferred by most people. It is called a "moisture trap" because, when installed as directed, moisture cannot access the food within the feeder; it allows complete sealing of the water area (normally covered with glass or plastic) except for the small area within the funnel itself. The neck's required opening is 3-1/2" x 5/8".

The smaller end of the rectangular funnel points upwards through the aquarium's cover and the larger, angled, wider end, which is cut to proper length, protrudes into the water by 1/2". That section MUST remain into the water at all times to prevent moisture within the aquarium's upper area from escaping through the funnel and into the space next to the feeder's chute. The funnel has a reach of 2-1/2". Normally, the distance from the water to the glass cover is within 1 to 2 inches. You may make your own funnel extension from thin plastic if ours is not long enough. You could also make a longer one shaped like a small gutter.

The use of the funnel may not be required depending on your type of installation, the type of food you are dispensing (pellets), and the level of "open air" moisture content around the feeder. With flakes, the use of the funnel is highly recommended. Also, by sealing the top of your aquarium directly above the water level, moisture from evaporation will be returned into the tank and water loss will be minimized. Furthermore, water pollution by uneaten food has been proven to be considerably reduced due to the fact that the fish will more readily eat the flakes as they slowly fall from the funnel at regularly programmed intervals. It will also help keep food away from skimmers.

The funnel below is the new ASF-1 Aquarium Super Feeder® "Moisture Trap™" funnel which is made of durable and slick non-stick polypropylene plastic. It is 3-3/4" long x 2" wide at bottom and 5/8" wide at the neck. It will fit between two glass panels by removing some hinge material, or a slot in rear plastic strip can be made (common on many aquariums).

ASF-1 installation in front of light fixture and with funnel between glass cover panels (small piece of hinge has been removed). The shaking slide at the chute opening expels the flakes into the funnel neck, which keeps the flakes from spilling around the cover.

Moisture Trap Funnel

Depending on your aquarium installation (low moisture generation) and whether you are using flake food or not, you may not need the Moisture Trap™ funnel. We only supply it to guarantee successful flake distribution under unusual moisture environments. If you decide to experiment feeding without the funnel, place the feeder at the side of a suitable aquarium opening (the smaller the opening the better) so that the outer edge of the feeder's chute outlet is about 1/4" from the edge of that opening. Many of our tests were successful, however, in order to guarantee our product, we still very strongly recommend the use of the Moisture Trap™ funnel, if at all possible, when dispensing flakes (pellets are no problem).
