Do It Yourself: How to construct an aquatic ecosystem


  • Enclosed Glass Jar
  • Distilled Water
  • Saltwater
  • Aquarium Gravel
  • Dried Sea Fan
  • LED Lamp
  •  7 – 8 Red Cherry Shrimp


  1. Clean your enclosed glass jar with hot water, but do not use soap. Soap will add chemicals to your ecosystem which may cause your shrimp to die.
  2. Add the aquarium gravel. The aquarium gravel should be anywhere from half an inch to an inch from the bottom of the glass jar.
  3. Add the sea fan. Some sea fans are covered with paint for decor, DO NOT use any sea fan with paint because this may also kill your shrimp. The sea fan should not float, but be positioned so that it says in place with the gravel.
  4. Get the distilled water and the saltwater. Use three quarter parts of saltwater and one quarter part of fresh distilled water. For example, if you have a 1 gallon jar three quarters of a gallon of the jar should be saltwater, and the other one quarter of a gallon should be fresh distilled water.
  5. Add the fresh distilled and saltwater mixture to your jar. Let this sit near a window for about a month, or until you start to see the growth of algae. This is very important, because algae is the source of food for the shrimp. Once the algae has formed, you can move it away from the window.
  6. Add the shrimp to your ecosystem and close the top.
  7. Place the jar anywhere, but not it near a window, because the water will heat up and kill the shrimp.
  8. Position the LED Lamp on the jar, so that the ecosystem receives light. The light should be on for 12 hours a day. It is important to get an LED Lamp, because unlike other type of lamps, LED Lamps will not heat up the water.
