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.

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!
