Product description:

Black and White Alkali Sand is an alkaline sand recommended for African Cichlids and Marine aquariums.

It is a mixture of black and white sand in different proportions, developed for a better aesthetic finish in aquariums. It has properties specially developed to alkalize the water.

It has granules with a size between 1.0 and 1.5 mm, ideal for a fine finishing.

The surface of the sand is prepared with special resins that make it difficult for algae to grow. Right after use, when filling the aquarium with water, the electrostatic generated in the sand is noticed, observing oxygen bubbles stuck to the granules and, after a few hours, these bubbles dissipate. With this protection, the aquarium substrate remains clean for much longer.

A product that comes clean and ready to use!

Crystal clear water on the same day! No need to wash!

The pH of the sand is alkaline and can vary between 8.0 and 9.5.

Note: It is an alkaline sand, for this reason, in some cases where the aquarium has acidification potential, it may be necessary to add alkaline materials as a complement to raise the pH.

Not recommended for use in upwelling, constant friction can strip the protective resin.

Packages:

• Stand Pouch 2 kg
• Package with 6 kg
• Economic bag 20 kg
• Bucket 25 kg

Indefinite validity.

How to calculate amount:

Sand density = 1.66

Calculation example:

Aquarium with 100x40 base

100 x 40 x desired substrate height x density (1.66) = result divided by 1000

Example: 100 x 40 x 4 x 1.66 / 1,000 = 26.56 kg

Result: 26.56 kg (A 25 kg bucket would be enough)
