Good for Pyrocystis
Used this to culture some Pyrocystis/bioluminescent dinoflagellates and its working well, the new cultures I made with the ferts are vigorous and healthy. Not sterile so take some caution but that's easy enough to overcome.

Stands up to thousands of reviews as best microalgae fertilizer
Great value! Only need 1 ml per liter! Can make 1000 liters of growth solution per bottle when mixed with filtered water. Odorless. High quality/easy to use. It is used to grow quality, healthy, vibrant strains of almost any type of algae or phytoplankton for science projects or climate research. Very useful!Personally, I am usually a critic before a proponent of the products I buy. But this fertilizer lived up to the claims. I use it to grow a few different species of algae, which I then use to add nitrogen to my compost bin. I also have a reef tank with wild grown live rock (which has to my knowledge, hundreds of different organisms that live attached or inside the rock). To keep them healthy, they need a steady supply of phytoplankton and certain algae. The live rock is over 2 years old and all the filter feeders, fans, and barnacles are still going strong!

My chlorella vulgaris is blowing up in density!
This stuff has helpled my chlorella vulgaris culture grow wonderfully! And its sheer size could last me multiple decades based on my math (which hopefully isn’t flawed)!Overall, wonderful product! Would recommend for any phytoplankton or algae culture!

Works
I bought this fertilizer to grow a culture of Tetra. I usually run about 4 different containers at once to equal about 5 gallons total of phyto. I put about 3 mL in each container on day 1. I also add about another 1.5 mL on day 5. I typically harvest on day 7-10 and the culture gets very dark. I have no complaints about this fertilizer and it works just as well as some other more expensive brands. I'm not even halfway through the bottle yet and I have harvested more phyto than I can use for my 300gal reef tank.
