What Is A Bioactive Tank
A Bioactive Tank, Terrarium or Vivarium is used to provide a Natural living settings for animals. This may include reptiles and amphibians like Dart Frogs, Tree Frogs, and Geckos. It may also include Insects, Small Invertebrates and Microorganisms Like Beneficial Bacteria, Mycorrhizae, Springtails, Isopods, Beetles and Millipedes. The latter are often referred to as Cleaner Crews.
Beneficial bacteria, Mychorizae along with Springtails & Isopods are a key component of Bioactive tanks and Enclosures. These organisms and arthropods consume and break down All the waste products of the main species that you keep in your tanks.
These Cleaner Crews are selected based on their ability to live symbiotically with the inhabitants of the tank or enclosure. When the cleaner crews are specialized for the inhabitants of the tank, then all forms of life in your tank will live together in balance.
No More Cleaning – Try Bioactive 
When all components of a Bioactive Habitat are balanced, All waste products will be properly broken down. This job of breaking down waste is done by the cleaner crew. You may never (or only rarely) need to clean your Bioactive Tank. All waste can be broken down and then turned into substrate. If plants are included in your vivarium, then the waste will be broken down and used as fertilizer. This will keep a cycle of Natural cleaning maintained.
Bioactive Tank Construction
Bioactive Tanks may be constructed of Glass, Wood, PVC or other materials. Inside A lot of users will utilize old aquariums , terrariums or even storage tubs.
Inside your tank or enclosure you will use a substrate. The substrate will cover several inches of the bottom. The substrate will be a natural material to colonize, burrow and lay eggs in. There are several forms or variations of substrate that may be used depending on the intended species or inhabitants to be housed.
Premium substrates exist such as those designed for Tropical Habitats or more Temperate Habitats. You may want to create a water based habitat or one with water features. If using a water feature then a drainage layer will be necessary. Including Drainage in your Bioactive Tank Works to aerate the substrate. The drainage layer will prevent too much moisture from saturating your substrate. If substrate remains saturated with improper drainage the enclosure can go anaerobic. If your tank goes anaerobic this may contribute to the breakdown and decay of the animal and plant life inside.
For Drainage layer use a material long used in hydroponics. Hydroton Clay Pellets will provide proper drainage. Hydroton is All natural and this organic material can separated with a screen. It may also be used underneath a false bottom
