This sand is a very fine, white substrate based on calcium and magnesium compounds. It is ideal for marine aquariums.
We recommend a layer of 2 to 3 cm, so that a sufficiently sustained current, generating good mixing, can rid it of detritus and prevent any concentration of nitrates on the ground.
Bora Bora sand is also optimal for mixing with living sand filtration systems (DSB method); in this case, the bottom substrate should be at least 8-20 cm high.
Made from very pure rock, Bora Bora sand does not release nitrates, phosphates or silicates. It is largely composed of calcium and magnesium and enriches the water with carbonates and bicarbonates of calcium and magnesium (measured by the TAC - or KH in Germany).
It is only about a year later that Bora Bora sand will have to be added, at a rate of about 10% of the quantity present in the tank; which roughly represents the dissolved volume over the past year in the form of calcium, magnesium, carbonates and bicarbonates.
The great fineness of Borar Bora sand is highly appreciated by molluscs, anemones, cerianthus, serpulids, plumed polychaetes, as well as labrids which like to burrow there. Gobiodons (family of gobies), too, dig it very easily to seek refuge there. Bora Bora sand corresponds perfectly to the natural environment of the coral reef and therefore plays an important role in the proper functioning of the biotope.
How much sand for my aquarium?
To give you an example: for an aquarium 150cm long, 50cm deep and 60cm high, you will need a bottom substrate with a thickness of 2cm.
Calculation: 150 x 50 x 2 Length x depth x desired substrate height = 15l = Liters.
8kg of Bora Bora sand is suitable for 5 liters of water.
Before use, be sure to rinse the Bora Bora sand well under running water – the water initially takes on a milky color; continue rinsing until the water runs almost clear.
