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.

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!

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!

Concentrrated.
I find this formula of F2 to be nicely concentrated. The amount to add to a culture, per their instructions, has worked well for me with my Nannochloropsis algae.

Guillard's F/2 Soution
I've been using Guillard's F/2 fertilizer for a few years growing phytoplankton. A very good product. I appreciate it being available now in 16 oz bottles.
