Black Lava Rock Porous Exotic Black Lava, 5 Stone 5 retailer

Product Name: Black Lava Rock Porous Exotic Black Lava, 5 Stone 5 retailer
These are the exotic black lava rocks of my choice. 100% All Natural Lava! 5 stones ~ about 5" - 7" These stones are perfect for your fish tank or reptile retailer aquarium. Exotic black comes in different natural textures, designed shapes and shades from dark to light black and rich mahogany This is a list I chose you to keep, so can't promise any color, size or texture. Dry rock lava does not affect the nitrogen cycle of the aquarium and can be added to new aquariums and existing tanks. My dry lava is very porous and has enough surface area to grow beneficial nitrifying and denitrifying bacteria, act as a biological filter and help maintain pristine water conditions in the tank. Aquarium Epoxy forms easily on dry rock, allowing you to craft beautiful columns, sturdy shelves, fun overhangs and cool caves -kjhdf.
