volcanit

Fresh water aquarium gravel

volcanit is a pH-neutral aquarium gravel of volcanic origin. The fine pore structure of the gravel encourages bacterial activity that enhances the biological release of nutrients from within the gravel. The results are superb plant growth. volcanit is mixed with 10% ferrolit, a natural long term iron fertilizer derived from Laterite. The resultant black and red colour enhances the beauty of the aquarium plants and the hues of the fish
