Brightwell Aquatics Reef Snow Coral & Invertebrate Food, 2L Marine Formula

Brightwell Aquatics Reef Snow is a 2L marine food supplement designed to nourish corals and suspension-feeding invertebrates with carbonate-bound elements, marine-derived proteins and lipids.

• Replicates natural marine snow with organic and inorganic nutrients — supports coral tissue and skeletal development.
• Provides major, minor and trace elements in aragonite ratios — supplies a range of elements used by reef organisms.
• Made for stony and soft corals, clams, tube worms, sponges, tunicates and other suspension feeders — suits a diverse range of marine invertebrates.
• Suitable for nighttime feeding — aligns feeding with when corals naturally extend their tentacles.
• Requires no refrigeration and contains no sugars or sugar derivatives — offers convenient storage without those ingredients.
• Formulated by a marine scientist and made in the USA — brings a science-led marine food to reef aquariums.

Reef aquariums contain organisms that obtain nutrients from suspended material in the water. Brightwell Aquatics Reef Snow is designed to provide a marine-snow-like source of nutrition for corals and other suspension-feeding invertebrates, including in reef aquariums and deep-water biotopes. Its formula combines mineral elements with marine-derived organic nutrients, addressing both tissue and skeletal growth needs.

What nutrients does Reef Snow provide?

Brightwell Aquatics Reef Snow combines carbonate-bound major, minor and trace elements with marine-derived proteins and lipids. The elements are balanced in aragonite ratios, and the formula supplies both organic and inorganic nutrients associated with coral tissue and skeletal development. This combination is intended to replicate the varied nutrient profile of natural marine snow rather than supply only one type of nutrient.

• Carbonate-bound elements include major, minor and trace elements.
• Marine-derived proteins and lipids provide the organic component.
• The formula contains no sugars or their derivatives.

Which corals and invertebrates is it made for?

Brightwell Aquatics Reef Snow is formulated for stony corals, including zooxanthellate and azooxanthellate types, as well as soft corals and other suspension-feeding invertebrates. Its intended range also includes gorgonians, clams, tube worms, sponges and tunicates, making it relevant to aquariums with varied coral and invertebrate life.

• For stony corals, whether zooxanthellate or azooxanthellate.
• For soft corals and gorgonians.
• For clams, tube worms, sponges, tunicates and other suspension feeders.

When should I feed Reef Snow?

Brightwell Aquatics Reef Snow is suited to nighttime feeding, when corals naturally extend their tentacles. Feeding at that time is intended to support nutrient uptake by corals as they extend to feed. This timing makes the supplement a useful option for reef keepers who feed their corals after dark.

• Night feeding takes advantage of the period when coral tentacles extend naturally.
• The formula is intended to support nutrient uptake by corals during feeding.

How is Reef Snow stored, and where is it made?

Brightwell Aquatics Reef Snow does not require refrigeration, so it can be stored without a chilled-storage requirement. The product is made in the USA and formulated by a marine scientist. Its 2L size provides the stated product volume for reef aquarium feeding.

• No refrigeration is required.
• Made in the USA.
• Supplied in a 2L size.

Reef Snow is suited to aquarists feeding stony or soft corals and suspension-feeding invertebrates, especially those seeking a marine-snow-like supplement with both mineral and marine-derived nutrients. It is designed for marine reef organisms rather than as a general-purpose food for unrelated aquarium animals. Its combination of carbonate-bound elements, proteins and lipids makes it a targeted option for coral and invertebrate nutrition.
