I am about to switch my tank over from 2 part to All for Reef. I wanted to make a simple reservoir that can also act as a mixing container as well. I figured a 32oz Nalgene water bottle would make a great reservoir since it also has measurements in metric and has enough extra space for mixing.
I ordered myself a green one off EBay for $10. I also got a 1/4” push connect bulkhead for $4, a piece of 1/4 acrylic tube for $3 and some colored silicone tubing for $6 from BRS. So far $23 total invested.
I drilled out the lid with with a step drill to fit the bulkhead fitting and melted a tiny vent hole in the top with a red hot needle.
I then proceeded to thread the bulkhead fitting in and measured where I need to cut the acrylic tubing at so that it sits just up from the bottom.
And tada! You have a $23 1000ml dosing reservoir. Not only is it inexpensive, you can also get extra nalgene bottles and have them ready to go. Just swap the caps.. easy peasy! There is also a 48oz version that uses the same lid so you can upgrade if needed and the bottles come in many different colors.
