Aqua Medic Volcanit is a rich gravel originated in volcanic regions. It is blended with 10% of ferrolit, an iron based fertiliser that is derived from Laterite.
The fine structure of the gravel is porous and as such encourages bacterial activity that promotes the natural release of nutrients. Plants will thrive - glowing with health and vitality as they feed on this rich diet.
The rich black and red tones of Volcanit looks naturally beautifully in any aquarium and shows off the exotic colours of fish and plants to their best advantage.
For another way to fertilise your aquatic plants, try Aqua Medic Terrapur, simply push the cones into gravel for a boost of nourishment.
