Spirulina Airlift Tube Blueprint
Spirulina needs gentle agitation. Mechanical propeller water pumps will chop up your algae if you use them to agitate your culture.
An airlift tube is a simple and healthy way of agitating your culture!
I have been using this design for over 10 years and they work like magic. This airlift tube is connected to an aquarium air pump by a .25” or 6mm aquarium tubing connected to the hole at the bottom of the air tube.
Below is the blueprint you can follow to make your own! It can be made from plastic, bamboo or clay. Have fun and make some for your friends!
