Algae Research Supply Algae Culture Porphyridium Cruentum, Perfect for School Science Fairs/Projects, Experiments & Classrooms (1000mL)

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

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.

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)

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!

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

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.

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

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.
