The coupling installation is only a few minute job. Drill a hole, slide coupling in, tighten and test.

The next step will be adding the misting nozzles to the vivarium.

Location with a single nozzle is going to be tricky on a longer, lower vivarium such as a 20 Long that is set up horizontally.
Taller enclosures will make location selection easier since you can aim down into the enclosure.

Aiming the nozzles from the front of the top (or sides) towards the back will lessen the amount of mist that would cover the front glass.

For my vivarium, I will add in an second nozzle to give better mist coverage.

Now for my questions to some build experts

  1. What drill bit is best used for drilling a hole into glass tops?
  2. Would you put the nozzles in by connecting inline to each other or parallel the hoses off a splitter (IE: "T")? And why?
