GrowTropicals Lava Rock (Fine Grade)
One of the bestĀ choices for that very chunky aeration in your substrate mix. Its porosity lends itself to well-draining mixes. Lava rock is also often used as drainage and/or as the sole substrate in terrariums where the plants donāt require a high level of nutrients.Ā
Lava rockĀ is also greatĀ drainage material for vivariums.Ā Lava rock is a great substrate that has a high surface area making it an ideal filter/drainage material that won't break down quickly. We recommend covering lava rockĀ with a materialĀ such as horticultural fabric or synthetic screening to preventĀ smaller-grained substrate materials from filtering down into it.
Lava rock is also an excellent biological filter. The large surface area lends itself to a high volume of beneficial bacteria, Nitrosomonas andĀ Nitrobactercomes,Ā that willĀ convert ammonia into nitrite and nitrite into nitrate respectively.
