Kent Phytoplex Phytoplankton 16 oz.
Kent Phytoplex is a highly concentrated complex of aqua cultured, naturally occurring marine phytoplankton. It contains Nannochloropsis, Tetraselmis, and Isochrysis sp. Tahitian, ranging in size from 2 to 15 microns.
Phytoplex provides essential proteins, carbohydrates, and lipids for live hard and soft corals, tube worms, clams, and other invertebrates. It is rich in omega-3 fatty acids, DHA and EPA, and is useful in feeding rotifers and other plankton, as well as in raising larval fish.
Phytoplex is grown in cold saltwater under laboratory conditions. It contains over 3 billion cells per capful and is approximately 15 times more concentrated than competing live cultures. One 8 oz. bottle contains more phytoplankton cells than one gallon of standard live cultures.

I’ve been using Phytoplex for my soft corals and tube worms for several months. The growth has improved noticeably, and my invertebrates seem more active. The concentration is impressive—much less product needed than other brands.

Great for feeding rotifers. The phytoplankton cells are visible and consistent. My larval fish have developed well since switching to this product. Easy to mix and store.

The DHA and EPA content supports better coral health. I noticed a difference in color and vitality after a few weeks. Highly recommended for reef keepers.
