systems are a lot of fun and really give a unique look to the vivarium. However
they do not work to replace a true misting system. The water particle size produced
by ultrasonic foggers is not large enough or in a sufficient abundance to
properly moisten anything but the smallest of vivariums. As it may look like
the humidity is increasing, the amount of water actually available to your
plants, mosses, and animals is quite limited and often merely condenses on
the glass. This method is presented to allow you to design a unique look and supplement to a misting system, but NOT
to replace it. A fogger alone will not be enough. This especially includes the in tank submersible foggers.
You will be using PVC tubing and electrically-powered
devices that use water. Use common sense.
Ultrasonic Air Humidifier (non-ultrasonic versions will not
1"-1.5" PVC tubing couplers
Plastic flexible tubing. ("Bilge Pump Tubing" at Home Depot)
Remove the plastic top fog directional piece from the ultrasonic
humidifier. This usually takes only a little force to snap off.
Insert a 1.5" pvc tubing coupler. Then insert into this coupler a 1" pvc tubing coupler. This will then allow your flexible bilge pump tubing to connect to your humidifier.
Now wherever your tubing ends, out will stream a billowing
fog that can quickly fill the volume of even the largest vivariums.
By planning ahead with your build, you can insert PVC tubing with holes drilled in it into your background. Then when connecting your fogger to this embedded piece, fog will stream out of the holes/cracks of your background. It is a very
unique look, especially if pumped out near the water level of your tank as the
fog will roll and cover the water first.
Make sure there are no spots where your tube can slag and begin
to collect water as this can fill up and plug your fog stream.
It is very important to use distilled or DeIonized water
only in your fogger reservoir as tap or spring water will contain solutes that
will adhere to your ultrasonic membrane and prevent it from working. If this
happens consult the directions of the humidifier.
In tank submersible foggers can be fun if used right. They work best in distilled water as solutes build up on their ultrasonic vibrating membrane rapidly. If you do want to use one of these, consider having a small container inside your vivarium that separates water and soil from getting into it. This way you can add distilled water into it and extend the life of your fogger. Personally I don't use these anymore as they tend to cost more than a much larger DIY system and have a much shorter life.
