Algae Research Supply Algae Culture Spirulina, Perfect for School Science Fairs/Projects, Experiments & Classrooms (50mL)

Amazing. High Quality. I used it to make more. I made a lot.

All i wanted was a nice little hobby and now i have so much algae, it cultured well once i got the light and nutrient mix figured out, took 2 weeks to get it from 500ml to 60 gallons (not fully dense but suited for tank size)

Before placing the spirulina into your tank, place couple drops under a microscope. I was sent a bottle of chlorella with spirulina mixed, it ruined my entire bioreactor set up. After 3 weeks of growth, I was able to get 1% spirulina. The rest was Chlorella. If you want to just grow algae just for fun, this would be what you need. If you want separate algae strains, go somewhere else.

They were very helpful with easy to understand instructions and videos.

I have cultured algae many times. I was not able to get anything going with this algae. I don't know if perhaps it got too cold in transit. It was for a lab I do with my middle schoolers and it did not work.

So far it has been growing very well under a grow light and using miracle grow (no fish in the tank). Was also definitely a great price compared to other sellers.

The cultures came extremely sparsely in their initial containers. I put them into a proper solution to let them propagate and a few weeks later I looked at it under a microscope. The majority of algae was not spirulina - it was something small and round. I did see a few pieces of spirulina but they were very sparse. At 40x magnification I could only count maybe 3. I'm gonna have to get another culture.

The algae arrived alive and in excellent conditions. We also send it to another country for a research and it arrived without problem.

Packaging was great and had detailed description of the contents. Great products
