RRA's Step 1
At the base of the food chain of a coral reef is phytoplankton, and there are a LOT of species out there; close to 2000 at that! now luckily for us, we don't need every single one of those species to see the benefits of live phyto. The aquaculture industry has validated the benefits of live phytoplankton, often citing an increase in color vibrancy and feeding response. The three best species available for everyday use in the reef tank are Nannochloropsis, Tetraselmis and Isochrysis galbana. We grow these three species separate and combine them for the ultimate live feed for your corals, filter feeding inverts and copepod population!
