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.

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.
