Give your fish and corals a highly nutritious marine food with Reef Nutrition Beta-Brine, a super-concentrated blend of enriched Artemia salina brine shrimp naturally rich in beta-carotene.

Beta-Brine is produced from brine shrimp aquacultured in Western Australian salt ponds and harvested while actively feeding on marine phytoplankton. The shrimp are flash-frozen to preserve their nutritional value and provide a convenient refrigerated food for marine fish, LPS corals, NPS corals and other reef invertebrates.

Important: Beta-Brine is not a live food. It is a refrigerated, concentrated marine food.

Why Beta-Brine?

Naturally Rich in Beta-Carotene
The brine shrimp feed on Dunaliella phytoplankton, a naturally beta-carotene-rich algae, helping make Beta-Brine an excellent food for supporting nutrition and coloration.

Whole Enriched Brine Shrimp
Provides marine livestock with nutritious Artemia salina in a convenient concentrated form.

Great for Fish & Corals
Suitable for a wide range of marine fish as well as LPS corals, NPS corals and other invertebrates.

Ideal Particle Size
Beta-Brine has a particle size of approximately 2,000–3,000 microns, making it suitable for many commonly kept reef animals.

Convenient Refrigerated Feeding
No thawing individual frozen cubes. Invert the bottle to mix, dispense the amount you need and return it to the refrigerator.

Available Sizes

16 oz – Great for regularly fed home reef aquariums.

32 oz – Ideal for larger aquariums, heavily stocked systems or reef keepers feeding Beta-Brine frequently.

Feeding Directions

Invert the bottle to mix before feeding.

Feed approximately 1–2 teaspoons per 100 gallons per day into a high-flow area of the aquarium.

For target feeding, mix 1 part Beta-Brine with 4 parts aquarium water before feeding. Undiluted target feeding is not recommended.

New users should begin at approximately half the recommended amount and gradually increase based on the aquarium's nutrient load and feeding response.

Storage

Keep refrigerated at 33–42°F (1–5°C).

Beta-Brine has a stated best-by period of approximately 6 months when properly stored.

Do not leave the product unrefrigerated unnecessarily, and return it to refrigeration promptly after feeding.
