Cool Earth

COOL EARTH (formerly Earthworm Plus) is formulated as a premium maturation diet made with fresh Canadian Nightcrawlers (Lumbricidae sp.).

Because COOL EARTH is dried at much lower temperatures than conventional flakes and pellets, the benefits of using cultured, fresh Canadian Earthworms are not lost in the processing. Like our other AQUANIX flakes, COOL EARTH delivers intact, complex proteins that are ideal for conditioning breeding pairs! Compared to other protein sources, earthworms are recognized as one of the best and most complete sources of amino acids for fish.

Cool cooking methodology, unlike pelleting, extrusion, and conventional flaking surpasses all other methods for preserving lipids and vitamins and maintaining the integrity of marine proteins and attractants - giving our customers even greater assurance that all the care, time and money that they spend on their show and reef tanks wll be equaled by our product.

COOL EARTH, like all AQUANIX Flake Diets, not only has exceptional water stability, but it contains viable beneficial bacteria that can facilitate the conversion of fish waste and uneaten food into harmless microbial biomass and carbon dioxide - so you'll see an improvement in water quality as well as in the overall health of your aquarium.
