DIY Kalk Doser


Difficulty Level – 1 (out of 1-5)

This DIY project is about as easy as it gets. The materials can be acquired for less than $5 and the project only takes about five minutes from start to finish.


Materials Required:


* 1 - empty 1 gallon water container
* 1 - 60” piece of 1/4” airline tubing
* 1 - 10” piece of 1/4” airline tubing
* 1 - airline regulator
* 1 - 9” piece of 3/16” rigid airline tubing
* pickling lime




Tools Required:


* Drill with 7/32" bit
* Scissors to cut the airline tubing to size

Step 1:
Drill 2 7/32” holes in the cap of the empty water container.

Step 2:
Push one end of the 60” piece of airline tubing about an inch through one of the holes in the top of the cap and connect it to the 9” piece of rigid airline tubing.

Push one end of the 10” piece of airline tubing about one inch through the remaining hole in the cap.

Step 4:
Attach the airline regulator to the opposite end of the 60” piece of airline tubing.


Step 5:
Add 1 teaspoon of pickling lime to the empty gallon container. Fill the container about a quarter of the way full with RO water and shake to mix. Next continue to fill the water container with RO water making sure to leave about 2 inches of head room at the top.


Step 6:
Screw on the cap to the container and adjust the rigid airline tubing so that extends to about an inch from the bottom of the container. After the kalk is mixed it will take a few minutes to settle. You want to make sure that the end of the rigid tubing is above this level because you do not want to siphon the sediment into the tank.


Step 7:
Open the valve on the airline regulator all the way and blow into the short piece of airline tubing to start the siphon. After the kalk begins to flow, adjust the valve to set the drip rate at about 1 drip every 1-2 seconds. Over time the regulator will become clogged up and will need to be soaked in vinegar to remove the calcium deposits.
