I made this one to always see the nutrient reservoir level in my hydroponic pot. 

You'll need:

  • A PVC pipe with an inner diameter of 17-18 mm (Don't worry, you can modify the sizes to your liking!)
  • A bit of (styro)foam
  • A few plastic straws, or something similar

With the floater, you can remove the bottom layer with a scissor, and then fill it with foam. Then, you clip a few plastic straws into each other, put a tiny drop of acrylic glue into the narrow tube, and insert the straw.
