DIY Protein Skimmers for Home Aquariums
- 1). Cut the top off the water jug. The cut should be just before the top flares inward toward the opening. The way the jugs are molded, there should be a small flange left when you cut. Save the top.
- 2). Hold the pump up to the side of the jug to measure where to drill the input and output for the drill. Mark and drill these holes.
- 3). Dry-fit the needle pump to the bulkhead fittings with short (under 4 inches) of PVC pipe using any necessary PVC adapters. Do not glue, only do this to make certain everything fits.
- 4). Cut an inlet and outlet hole into the jug and affix PVC bulkhead fittings. Again, do not glue until make sure all the pieces fit together right when dry.
- 5). Disassemble all fittings and pipes, then glue them together with PVC glue. Allow to dry per manufacturer's instructions, plus about 24 hours for safety. Also, glue the top of the jug back on with aquarium glue.
- 6). Cap the top of the jug and create a spigot for scum with curved PVC fittings. Place a length of PVC at the end of this, leading into a collection bucket for the aquarium waste.
- 7). Run a line to a test bucket of water (instead of your aquarium) once the glue is dry. Place the skimmer in a large tub to leak test it. If it holds water for 48 hours, continue.
- 8). Plumb it to your aquarium or sump if it does not leak. Activate the pump and empty the waste container as needed.
