If you want to get started culturing chlorella, your about to learn how to get started in 3 easy steps.
2. Algae Grow
When I first looked I found it nearly impossible to find good cultures luckily I found the Carolina Biological Company, best of all they sell bacteria free chlorella. You want to get chlorella vulgaris, that is one that is used in suppliments and biofuels.
The culture comes in a tube in the next 2 days. So I suggest you get your container ready to go BEFORE you buy your chlorella.
A simple jar, or water bottle will work. A 6.5 gallon tank is a great starting point, however I suggest getting a 10-20 gallon tank if you want to have a larger yield.
Heres a link to typical 6.5 gallon tank I would reccomend:
I recommend also getting a whisper pump to get plenty of CO2 into the tank that will dramatically increase the chlorella’s ability to grow.
You need to feed your algae a complex mix of minerals and salts if you want them to grow efficiently. Theres no better way to do this (currently) than with the algae grow from Carolina Biological.
I of course did all of the above, heres my current set up with a healthy culture after about 1 week.
Note: I wouldn’t consider harvesting this for food. These conditions aren’t satisfactory for personal consumption. However the culture is completely bacteria free and could be cultured for such a use, the problem is my container isn’t ideal. I’ll have to come up with another tutorial on sterile conditions in the future. Great for biofuels or just reducing CO2 emissions.
