Sea sand for bottom substrate or reactor
SANDSEA sand is ideal for the bottom of a marine aquarium (reef or fish only) as well as for Malawi Cichlid aquariums.

It is largely composed of calcium and magnesium, so it can also be used as a consumable in a limestone reactor.

Important! Before use, rinse the sand thoroughly with running water. The water takes on a whitish color. Wash the sand until the rinse water becomes clear.
It takes about 2 to 3 cm for an aquarium background.
