ZEOfood contains amino acids and vitamins for optimal coral growth. ZEOfood increases bacterial growth that supplies corals with all necessary elements for healthy growth. If used in combination with Zeobak levels of nitrate and nitrite are reduced. ZEOfood can also be used in aquariums where ZEObak is not used to substantially accelerate the growth of beneficial bacteria. This forms the basis of biological recovery and promotes coral coloration in nutrient-poor aquariums. Dose directly into the tank 1-2 drops per 25 gallons/100 liters per day.
