### ⭐⭐⭐⭐⭐ Stands up to thousands of reviews as best microalgae fertilizer
*by M***A on October 2, 2024*

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!
