How to Make Dosing Jugs

Project Ease:  2 (scale of 1-10, 1 being the easiest)

Project Cost:  Free up to $10

This is a very simple project to help clean up your tank space and prevent spills.  I had all supplies on hand, so the cost was essentially free to me.  If you had to buy everything, this project will cost about $10 to make three jugs (magnesium, calcium, and alkalinity.)    

Supplies:

  • 3 Jugs – size to fit your needs.  I used gallon jugs from Bulk Reef Supply in two different sizes to fit under my tank.
  • 3 Airline fittings (most big box fish stores carry these)
  • Airline Tubing (carried by most LFS and big box fish stores if you don’t have some extra lying around)
  • Hard RO water line (carried by many LFS and online).  I used about 3 feet, but size to your containers.
  • Super Glue
  • Drill (Yeaaah!  Power tools!)
  • Drill Bit (Size to your airline fittings.  I used a 7/32″ drill bit.)
  • Safety Glasses
  • Scissors
  • Measuring Tape

Instructions:

1.  Gather your supplies.  Ask for help if you aren’t comfortable working with power tools.  Put on safety gear.

2.  Measure the height of your jugs from the bottom to the top without the cap.

3.  Cut the hard RO water line an inch shorter than the height of the jugs (e.g. if the jug is 12″ tall, cut 11″ of line).  This is to keep the dosing pumps from sucking up the precipitates on the bottom of the jug.  Place these to the side.

4.  Drill a hole in the top of each jug’s lid for the airline fitting.  Test fit the fitting.

5.  Add a very small amount of super glue to the airline fitting where it will touch the lid.  Insert the fitting into the lid.

6.  Make sure there is enough of the fitting sticking out on both sides for the water line and air line to attach.  Let it dry.

7.  Attach the RO water line to the underside of the lid on the fitting.  If it feels loose, you can add a dab of superglue (be sure to not clog the lines with it though!)  You can also cut the line shorter if necessary.

8.  Measure the distance from where the jugs will be placed to the dosing pump.  Add a few inches to this number (it’s easier to take off than add on) and cut the flexible airline tubing to size.

9.  Attach the airline tubing to the top of the airline fitting.  Voila!  You now have awesome functional dosing jugs.  I added some pretty labels to each jug as well.
