The dream of every aquarist is for their tank to be as clean, healthy, and vibrant as possible.  The addition of phytoplankton to an aquarium can help establish a natural food web in your tank that closely mimics the natural marine environment and will make your tank inhabitants happier and healthier, as well as improve water quality and clarity.

Live phytoplankton should be stored in the refrigerator for up to three months or until the mixture loses its bright green color, settles to the bottom of the container, or starts to smell. Shaking the bottle every few days will prevent cell death.


Dose directly around corals with a pipette or turkey baster. For indirect tank dosing, start with 5mL phyto per 20 gallons daily.

Adjust dose after a few weeks to better suit your tank needs. It is recommended to stop any skimmers while dosing.
