This is the only totally-comprehensive guide to creating an aquatic self-sustaining ecosystem, or Jarrarium, on the Internet.
Too many animals can result in all the plants getting eaten and oxygen used up too quickly. Too many plants may result in overcrowding and death. Read more about the abiotic and biotic factors of an ecosystem.
Ecosystems can be open or closed systems. Closed systems, such as ecosphere shrimp, are entirely sealed from the outside world. Open systems are more like a traditional fish tank system with an open lid. Aquatic terrariums can either be fresh or saltwater, although due to the chemical complexities of saltwater, freshwater systems are considered easier to set up and run. In terrestrial terrariums, moss is a common base plant for sealed systems.
Ideally select slow-growing plants such as:. The type of plants you use will depend on the type of soil. For example, soil requirements for cactus and succulents will differ to that of moss. The type of animal will depend on the size of the enclosure. Shrimp prefer to be kept in pairs or social groups and require at least 1 gallon of water per shrimp.
As we said, a small container often prevents the ecosystem from growing properly and the elements within from interacting correctly with each other.
Larger containers allow for the inclusion of multiple diverse species and give everything room to evolve naturally. Here are some things you need to know about containers:.
If you want to build a terrarium for plants, make sure you get a bowl or a container that is sealable. Both plant terrariums and fish aquariums need substrates to begin. Each of these two self-sustaining ecosystems features different substrates: soil or water.
Let us see how to begin:. Add the first layer of small pebbles on the bottom of the terrarium. They will allow the collection of water without flooding the plants. Next, add a thin layer of activated charcoal to filter the impurities in the water and keep fungi and bacteria at bay, preserving the ecosystem clean and healthy.
Top the charcoal layer with peat moss to hold the water and nutrients necessary for the plants to grow. On top of the peat moss, you can add the potting soil. The first thing to add to an aquarium is a layer of sand and pea gravel to allow the plants to anchor and grow. Next, fill the container with water.
If you use distilled or bottled water, you can also add some nutrients to promote growth. What makes a true ecosystem is the ability of its inhabitants and their environment to work together to support the system. A series of finely tuned life cycles and energy transfers that will make or break the system.
Remember, a zero-maintenance plant terrarium is one where we should never need to prune or remove plants that get too big. If your terrarium is crammed in with material, it can develop air pockets, starving some plants of their much needed sustainance.
Broad, evenly shaped containers like cubes, spheres, fish tanks and wardian cases are best. See my guide to Glass Terrariums on Etsy for some inspiration. Bright, indirect light is pretty much the gold standard for most terrarium plants. North facing windows are often a great choice, as they never receive direct sunlight, but they are still well lit throughout the day.
Or, you could always put your terrarium under a grow light if you really wanted to control the lighting as much as possible. A functioning water cycle is the lifeblood of a terrarium ecosystem. Building a terrarium foundation that supports the movement of water — whilst retaining it where necessary for plants to access it — is the key to a healthy water cycle.
For more help on watering, see my full guide to watering terrariums. The decomposition process of the natural world is perhaps the most difficult part to replicate in a terrarium. There are probably thousands of different species at work in your local woodland, all working in harmony to break down and regenerate biomatter. These tiny natural cleaners make a great addition to any terrarium. Transforming it from a potentially deadly terrarium hazard to a wonderful new source of nutrients.
Mould is their favourite food, so you can say goodbye to those awful white fuzzy blooms.
