Fluval Plant and Shrimp Stratum 8lb

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).
