A multi-species live phytoplankton blend, cultured in small batches and bottled fresh — not freeze-dried, not powdered. It's the base of the reef food web: food for corals, clams, and feather dusters, and the copepods & rotifers that feed everything else in your tank.
Includes: 16 oz (473 mL) bottle of live, multi-species phytoplankton — enough for weeks of dosing in most tanks.
We're currently farming our first live cultures, so bottles aren't available yet — get in touch to be notified the moment they're ready.
Corals, clams, and feather dusters evolved filtering live phytoplankton out of the water column — not a dry flake or a bottle that's been sitting on a shelf for months. Dose live cells, and you're feeding the whole tank, not just the show pieces.
Actively growing cells, not freeze-dried powder or a preserved concentrate — closer to what filter feeders evolved to eat.
Different cell sizes and nutritional profiles in one bottle, so more of what you dose actually gets eaten by something.
Corals and clams take it directly — and it fuels the copepods & rotifers that feed your fish, mandarins, and pipefish.
We grow it in small batches and bottle it fresh, so what you get is dense and lively — not diluted or past its prime.
Packed to keep the culture cool and calm in transit, so it arrives alive and ready to dose.
No mixing, no rehydrating — shake the bottle and dose it straight into your tank's flow.

Every tank's bioload and feeder population is different, so start light and watch how your corals and water respond.
Cells settle over time — give the bottle a good shake before every use.
Pour or drip it near a pump or high-flow area so it disperses through the tank instead of clouding one spot.
Begin with a small amount, watch polyp extension and water clarity, then adjust up gradually to fit your system.
Keep it cold and out of direct light to keep the culture fresh between dosing.
We're in the process of farming our first live phytoplankton cultures. Want a bottle (or a standing order) reserved for launch? Drop us a line and we'll save one for you.
