Natural white sand obtained from a very high quality substrate. He is free from all contaminating. Thanks to its calcium carbonate content, it stabilizes the physico-chemical parameters of aquarium water. Due to its composition, the application of AF organic sand considerably accelerates the aquarium maturation process and allows faster colonization. The bottles included in the kit contain strains of insulated nitrifying bacteria in laboratory and an environment facilitating their development and their multiplication. The special kit of the kit guarantees the implementation of the nitrogen cycle and the elimination of the harmful chemical compounds of water much faster than in the case of traditional substrates. Extremely simple AF operation organic sand allows you to quickly prepare sand to use in the aquarium. The granulometry of the sand is between 0.5 and 1.5 mm.

We do not recommend storage in fresh places, as this can considerably increase the bacterial multiplication time. The optimal sandy temperature of the sand is around 25-28 ° C. After 24 hours, the sand thus prepared is ready to be used in the aquarium. Keep away from children. Product for aquarium only. Not suitable for human consumption.
