Cool Green

COOL GREEN is prepared using Low Temperature (LT) Cooking Methodology and is formulated for the needs of herbivorous and omnivorous fish, both marine and freshwater species. Our process results in a soft-bodied, naturally green, leaf-like flake. Formerly PhytoPlankton Plus.


5.0 out of 5 stars  My goto marine food

Reviewed in the United States on April 2, 2021

My reef tank prefers cool green over just about everything but ROE. My most finicky fish (purple queen anthias) will eat this over frozen mysis. And it's affordable enough to feed to my koi fry as well.


COOL GREEN provides herbivorous fish with a wide array of plant proteins and natural color enhancing compounds derived from spirulina (Arthrospira platensis), kelp (Ascophyllum nodosum), chlorella spp., schizochitrium limacinum, Paracoccus carotinifaciens, and garlic. And, because Cool Cooking Methodology gently dries our mixtures at half the temperature of conventional flaking and pelleting processes, we are able to maintain the integrity of delicate organic compounds found in nature.

Low temperature (LT) cooking methodology surpasses pelleting, extrusion, and conventional flaking processes for preserving lipids and vitamins and maintaining the integrity of marine proteins, flavourants and attractants - giving our customers ever greater assurance that all the care, time and money that they spend on their show and reef tanks will be equaled by the pride we take in our product.

(Spoiler alert: The testimonial from the fish is the best!)

COOL GREEN also includes beneficial bacteria to facilitate the conversion of fish and food waste into microbial biomass and harmless carbon dioxide. Unlike beneficial bacteria touted in conventionally processed flakes and pellets, the bacteria in COOL GREEN remain viable through the Cool Cooking process.

To aid in the sustainability of our ocean’s resources, we've added highly nutritious black soldier fly larvae to our LT diets. This allows us to reduce our reliance on pelagic fish, krill and other resources that are increasingly under pressure. We don't cut corners in the formulation of our flakes, but we do try to make effective use of the proteins that are available to us!
