The Green Water Machine is a one gallon jar kit that comes with everything you need to make your own live green water. I’m using “Green Water” as an umbrella term for a living culture primarily consisting of multiple species of single cell algae and other infusoria. This kit includes a live green water starter culture that is perishable. It's best to start your green water culture kit within 24 hours or so after receiving it. This kit also comes with enough algae fertilizer/nutrient to make 3 gallons of green water. Algae nutrient and live green water starter cultures are also sold separately.

How to Use This Kit
Step 1: Thoroughly wash jar and lid with diluted bleach solution or just warm water. Dry jar and make sure all bleach is thoroughly rinsed.
 
Step 2: Shake the live green water starter culture in the sealed bag. It can settle during the shipping process. Add starter culture to the jar.
 
Step 3: Fill the jar with water to the bottom of the jar shoulder. This water can be bottled spring water, well water or filtered water. Dechlorinated tap water or aquarium water can be experimented with. Ideal water temperature range is 60 - 80 degrees F. Can probably handle cooler or warmer temperatures.
 
Step 4: Add 4 ml of algae nutrient to the jar. Use the plastic pipet (included with kit) and fill to the 4 ml line.
 
Step 5: Add a small pinch (1/16 teaspoon) of culturing salts to the jar. This is for buffering the alkalinity and adding beneficial micronutrients for the algae. The live green water starter culture that comes with this kit is a freshwater algae. You do not want/need to add marine salt to the culture water to make it into “seawater” . A little pinch of culturing salts will not turn the culture into saltwater. 
  
Step 6: Hook up air. I would always recommend aeration when growing green water. If air is unavailable then stirring daily with a large spoon or other utensil will be necessary. The rigid air line feeds through the hole in the jar lid. Attach the flexible air hose to the rigid air line by easily sliding the hose over the line. Place the air control valve in-line with the air pump to control your bubble rate. It is beneficial to have a high flow in the green water culture so lots of air flow is necessary.
 
Step 7: Lighting. This living algae culture needs light to grow. This can be as simple as an inexpensive LED Daylight bulb or LED strip shop light in the color temperature range 5000K - 6500K. You’ll have to experiment with the on off light cycle and distance from the bulb to the culture water surface. You can start with lights on for 12 to 16 hours a day and place the culture 12 to 20 inches away from the light bulb or strip. You can also have success growing green water with the sun by placing the jar in a south facing window. You will want to experiment with placing the culture in indirect sunlight to full sun.
