Lavtas  Volcanic Sand for Planted Aquariums.
Planted tanks require a substrate that will remain loose enough for plant roots to penetrate it. The substrate should be chemically inert.Substrates are added to most aquaria principally for the increase in beneficial bacteria this provides.
Lavtas is a pH-neutral aquarium gravel of volcanic origin. The fine structure of the gravel encourages bacterial activity that enhances the biological release of nutrients from within the gravel. The results are superb plant growth. Our Lava Sand Granule size is 10-13 mm.
