This aquatic substrate is ideal for growing and cultivating freshwater
plants. The characteristics of this Stratum are naturally occurring from the
foothills of Mount Aso Volcano. The individual bits of the substrate are
porous, allowing beneficial nitrifying bacteria to grow all over the surface
of each granule and keep the water quality in the optimal range. The gravel
itself will keep the water in the neutral to slightly acidic pH-range; which
is ideal for freshwater plants, most shrimp and small schooling fish
generally kept in planted aquariums. It is noncompacting, and allows plenty
of space for plants to root in the soil and absorb the nutrients that are
naturally present in the substrate. It will not discolor the water, and can
actually help to stop natural wood tannins from discoloring the water as well!
Manufacturer's warning: Do not mix with other substrates, and handle with
care when changing the
water (do not stir).
