Step 5 — Bioavailable Nourishment / Pure Phyto™

Reef Essential® · Phytoplankton

Marine phytoplankton, without the fridge or the fuss.

Pure Phyto™ delivers natural marine-based phytoplankton and phycocyanin extract — protein, fats, fatty acids, vitamins, and natural color enhancers — aquacultured in ultra-pure saltwater with no fillers, heavy metals, or harsh extraction chemicals. Especially important for NPS corals, which get no nutrition from photosynthesis at all.

Not all coral nutrition comes from light

Photosynthetic corals get a lot of their energy from zooxanthellae, but non-photosynthetic (NPS) corals get none of it — they rely entirely on what you feed them. Pure Phyto fills that gap with real phytoplankton, the base of the marine food chain, rather than a synthetic substitute.

It's designed to combine easily with the rest of the Step 5 lineup — mix Pure Phyto with Bio-Enhance and Coral Cane for a single complete feeding, or dose it on its own as a standalone broadcast feed.

What makes it different

Pure Phyto is built around purity — no shortcuts in sourcing or extraction.

01

Contents

Deionized water plus phytoplankton and phycocyanin extract.

02

No refrigeration

Store at room temperature — many phytoplankton products require cold storage, this one doesn't.

03

Aquacultured, not wild-harvested

Grown in ultra-pure saltwater specifically for this product, for a consistent, clean final product.

04

Broadcast feeding

Turn off the return pump but leave the protein skimmer on. Let corals consume it for at least 30 minutes, then turn equipment back on.

05

Target feeding

Mix 3mL Pure Phyto with 1mL Bio-Enhance and 4mL tank water, then feed gently with a pipette or baster.

06

Combine with Coral Cane

The Aqua Care Guide™ mix is 1 scoop of Coral Cane®, 1 mL of Bio-Enhance™, 3 mL of Pure Phyto™ and 4 mL of aquarium water, mixed together before feeding.

Dosing guide

Twice-weekly broadcast feeding, scaled to stocking level. Shake well before dosing. Not for use on a dosing pump.

Stocking level Dose (2x per week)
Lightly stocked 5 mL per 100L (26 gal)

Heavily stocked 10 mL per 100L (26 gal)

Questions about this product

Do I need this if I already dose Bio-Enhance?+
They cover different things — Bio-Enhance is a liquid nutrient blend, while Pure Phyto is whole phytoplankton. Many reefers run both, and NPS corals in particular benefit from real phytoplankton specifically.
Do I need to turn off my skimmer to feed this?+
No. The manufacturer says to leave the protein skimmer on for both broadcast and target feeding; turn off the return pump (and circulation pumps for target feeding) for at least 30 minutes.
Does this need refrigeration like other phytoplankton products?+
No — unlike many phytoplankton supplements, Pure Phyto doesn't require cold storage.
