Review on Pack Seachem Reef Phytoplankton 16 9 by Angeline Darpino

I tested this phytoplankton on my reef tank and noticed a significant improvement in the health and color of my corals and other invertebrates. As a result of my tests, I determined that this product truly boosts the overall ecosystem in a reef aquarium. The only downside is that it needs to be refrigerated after opening but this is a minor inconvenience compared to the benefits it provides. Highly recommend for any reef keeper looking to enhance their tank..
