Algae Research Supply Algae Culture Spirulina, Perfect for School Science Fairs/Projects, Experiments & Classrooms (1.7mL)

Great quality algae, with no contamination from other species. Used it for growing my own fertilizer. Algae sample was very much alive, and reproduced very quickly!

I picked an amount that was too small for my needs and decided to try it anyway. I setup a small container with pH and nutrients as instructed. The thing had mega air flow from my pump that brews my compost tea and tons of proper lighting. Thermometer and controller for heat and the stuff never grew any more algae. It was pretty cold in MN when this arrived so most likely the algae was DOA.

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

This much product would have been $7 before greedflation but it has quickly propagated so …there’s that.

I bought a smaller batch a couple months ago that wasn’t nearly as alive, but even though this one came frozen solid, it’s culture is booming. I use spirulina for home air purification because they are pigs for co2. I’m pretty much knocking off an actual overpriced product that has some solid science behind it. (Algen air). Their product is sleek like Apple made it, but it’s lacking an adequate light and bubbler, and there’s no heater which is key. It retails for 200, but you can make your own “aquarium style” in any glass container you want for under 40. When you feed the culture, I bring some spring water to a boil and dilute the mixture, let it cool and you’ll immediately see more activity. Grow on!

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.

I liked the pencil

3 stars because i didnt do it right :( so its probably my fault that nothing grew
