Not sterile so take some caution but that's easy enough to overcome. ### ⭐⭐⭐⭐⭐ If it dont work. Its because you are doing something wrong *by on Reviewed in the United States August 3, 2026* Works great. ### ⭐⭐⭐⭐⭐ Stands up to thousands of reviews as best microalgae fertilizer *by on Reviewed in the United States 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! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/376461111-f2-ferts-32oz-super-concentrated-guillards-f-2-formula-mass](https://www.desertcart.sn/products/376461111-f2-ferts-32oz-super-concentrated-guillards-f-2-formula-mass) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-14*
