Red Sea Reef Base Aragonite Pink 10 Kg

Premium aragonite for marine & reef aquariums

• Premium quality, natural aragonite high in essential elements.
• Promotes stability of pH and alkalinity (KH) levels.
• Easy to use, ideal for all marine fish and corals

Facts about Red Sea Reef base:

• An oolitic aragonite substrate, formed through natural precipitation and collected from renewable source.
• Will help maintain a stable pH of 8.2-8.3.
• Prepared by being exposed to air & UV light, screened, and mechanically washed. A second washing results in a cleaner substrate.
• Live Reef Base contains millions of beneficial laboratory-engineered bacteria, which will speed up the maturation process and allow quicker introduction of corals.
• The bacteria is  gelled  onto the grains and packed in sterilized natural seawater.

Truly renewable pure calcium carbonate aragonite sand material formed naturally through precipitation and sedimentation in the Bahamas.

Specifications

• Material: oolitic aragonite — pure calcium carbonate, formed by natural precipitation in the Bahamas
• Grain size: 0.5–1.5 mm
• Pack: 10 kg bag
• Buffering: helps hold pH at 8.2–8.3
• Preparation: air and UV exposed, screened, then mechanically washed twice

This is the dry Reef Base, not the Live Reef Base — it carries no bacteria and is not packed in seawater. Red Sea do not publish the grain size on their own product page; the 0.5–1.5 mm figure is the one their distributors list, and it puts the Pink a step coarser than the White.

Setup & Use

Rinse before use. This is a dry, washed substrate rather than a live one, and a rinse in RO or old tank water saves you a day of cloudy water.

Spread it evenly, then fill onto a plate or bowl so the bed is not disturbed. At 0.5–1.5 mm it is fine enough for sand-sifting gobies and burrowing wrasses, and light enough to be moved by a powerhead aimed at it — angle flow across the tank rather than down at the sand.

A 10 kg bag covers roughly a 60 x 30 cm footprint at a 25 mm depth. Buy the full quantity at once: natural aragonite varies in shade between batches, and a bed topped up later shows the join.

Because it is dry, the tank still has to cycle. Add a bacterial starter or a piece of mature rock, and test ammonia and nitrite before adding livestock.

Freshness & Storage

Every batch we dispatch carries a minimum of 6 months’ remaining shelf life. Store this product in a cool, dry place away from direct sunlight, with the cap or inner foil closed tightly after each use.

Filter media and substrates carry no manufacturing or expiry date — their working life begins on first contact with water, not on the shelf.
