DIY Venturi Skimmer Plans
Venturi skimmers produce fine bubbles that remove metabolic waste. (aquarium fish 8 image by cherie from Fotolia.com)

The water quality in any aquarium drops as soon as fish are added, due to the presence of their metabolic waste. Venturi skimmers remove these organic products and allow hobbyists to keep fish and invertebrate animals, such as starfish and anemones alive for extended periods of time. A venture skimmer is so named because it produces the fine bubbles required to function correctly, via a venture valve. These powerful skimmers are powered by impeller driven pumps and are typically larger than air stone driven models. The following venturi skimmer is designed to stand in the remote reservoir or sump that is positioned below most marine aquariums.

Instructions

  1. 1

    Drill a 1/4-inch hole in the smooth end of one of the three, 1-inch barbed fitting.

  2. 2

    Boil water and pour into a shallow bowl. Place the end of the 1/4-inch silicone air tubing into the shallow bowl of boiling water. Remove after 30 seconds and push into the 1/4-inch hole in the barbed fitting.

  3. 3

    Allow the barbed fitting to dry. Uing a quarter teaspoon of silicone, glue the air tubing into place in the barbed fitting. Leave to cure for at least 24 hours.

  4. 4

    Screw the barbed fitting into the exhaust nozzle of a GenX -2400 volute submersible pump.

  5. 5

    Cut a 1.5-inch diameter hole in the 10-gallon bottle at the point where the neck begins. Place the 4-inch long, 1.5-inch-diameter pipe into this hole. At least 95 per cent of the length of the pipe must stick out of the bottle. Seal the 4-inch pipe into the hole with a teaspoon full of silicone sealer and leave to cure for at least 24 hours.

  6. 6

    Place the 10-gallon plastic bottle on a table top and position the first GenX -2400 volute submersible pump with the barbed fitting pointing at and touching the bottle. Position the pump on the opposite side of the bottle to the 4-inch pipe.

  7. 7

    Mark the point where the barbed fitting touches the bottle and cut a hole in the bottle to accept the tip of the barbed fitting.

  8. 8

    Use half a teaspoon of silicone sealer to secure the barbed fitting in place. Leave to cure for at least 24 hours. This pump will function as the venturi component of the skimmer.

  9. 9

    Screw the second barbed fitting into the exhaust nozzle of the second GenX -2400 volute submersible pump.

  10. 10

    Place the second GenX -2400 volute submersible pump on the table top, next to the first GenX -2400 volute submersible pump with the barbed fitting pointing at and touching the bottle.

  11. 11

    Mark the point where the barbed fitting touches the bottle and cut a hole in the bottle to accept the tip of the barbed fitting.

  12. 12

    Use a half a teaspoon of silicone sealer to secure the barbed fitting in place. Leave to cure for at least 24 hours. This second pump will supply the skimmer with aquarium water.

  13. 13

    Cut the bottom off a 1-quart plastic bottle and remove the cap.

  14. 14

    Remove the cap of the 10-gallon bottle. Place the spout of the 1-quart plastic bottle into the spout of the 10-gallon plastic bottle and apply a teaspoon of silicone sealer to the area where the two join. Spread the silicone around the joined area to ensure a watertight seal. Leave the combined unit to dry for at least a day.

  15. 15

    Place the skimmer and attached pumps into the sump of the aquarium. The 4-inch-long plastic pipe must be above the water level.

  16. 16

    Attach the loose end of the 1-foot silicone air tubing to the rim of the sump, using the plastic clamp.

  17. 17

    Plug both submersible pumps into a wall power source and switch on.
