Seachem Reef Zooplanktonis a concentrated, protein-rich blend of marine zooplankton built on artemia and rotifer species, sized from 12.5 to 500 microns to feed the larger mouths of stony corals. It delivers essential fatty acids, proteins, amino acids, vitamins, and natural carotenoids that drive coral growth and color while adding antioxidant support.

What It Feeds
- LPS (large polyp stony) corals such as acans, frogspawn, and torch corals
- SPS (small polyp stony) corals
- Anemones and other larger-mouthed reef invertebrates
- A broad range of marine inhabitants thanks to the wide 12.5 to 500 micron size range
Why Reefers Use It
- Protein-rich.Built on artemia and rotifer species for the meatier diet stony corals prefer.
- Wide particle range.12.5 to 500 microns suits LPS, SPS, and many other reef feeders.
- Natural carotenoids.A bioavailable pigment source that supports coral color and acts as an antioxidant.
- Pairs with phytoplankton.Use alongside Reef Phytoplankton to cover both soft and stony corals.
How to Use
Shake well before each use. Add 1 capful (5 mL) for every 200 litres (about 50 US gallons) twice a week, or as needed to support coral growth. Rather than spot feeding, disperse Reef Zooplankton throughout the aquarium so corals can capture it from the water column. Start conservatively and increase only as your corals respond, since any food adds to the tank’s nutrient load if overdosed. Refrigerate after opening for the best shelf life.

FAQ
What does Reef Zooplankton feed?
It is a protein-rich food for LPS and SPS corals, anemones, and other larger-mouthed reef inhabitants. For soft corals and filter feeders, pair it with Reef Phytoplankton.
How is it different from Reef Phytoplankton?
Phytoplankton is a 1 to 20 micron algae-based food for soft corals and filter feeders. Zooplankton is a larger 12.5 to 500 micron protein-based food for stony corals. Many reefers use both.
Should I spot feed it?
No. Disperse Reef Zooplankton throughout the aquarium so corals can capture it from the water column rather than aiming it at individual corals.
Do I need to refrigerate it?
Refrigeration is recommended after opening for the best shelf life, but the product is preserved and stable at room temperature.
