Substrate Jungle Sugar

White and fine sand for the bottom of aquariums containing a bacterial Culture Starter that triggers rapid logical maturity, ideal for freshwater aquariums. Rapid logical maturation thanks to the bacterial Culture Starter - grain size 0.1 mm - 0.6 mm - neutral pH - no sharp edges - resistant to CO2 - does not harden the water. Very fine white sand for the bottom of freshwater aquariums with a specially formulated bacterial seeding culture, packaged in pouches in a separate box. The bacterial strains are dehydrated and stored away from light, on a logical mineral substrate. This means they are not affected by the environment (temperature variations, deposits) as a liquid product would be.
