Review: This is a great product to culture microalgae. In the past I've used Miracle Gro with mostly failure where the culture would completely crash relatively quickly. This nannochloropsis culture got dark quickly and has remained alive for more than a 3 weeks now, there's a power head in there that you cant even see anymore.
Review: Great for growing my phyto for my reef. Thank you to the seller for using biodegradable peanuts for packaging, had fun melting them.

I learned this the hard way- you must use 2x the suggested amount in order for your phytoplankton to thrive. Whenever I use only the suggested amount the whole batch dies
