Product Description

Color: Volcano Red

SubstrateSource Natural Lava Gravel is a highly porous substrate for use in freshwater aquariums. The lava has been screened to remove large granules and can be used as a complete aquarium substrate system.

Nutrients: The lava has not been treated with additives or altered from its naturally inert state; however, it does have a high Cation Exchange Capacity (CEC). CEC is a measure of a substrate's ability to store and release compounds including critical nutrients for healthy plant growth. These nutrients are absorbed from fish waste or fertilizers added to the aquarium and made available in the substrate bed, at the root site.

Color & Size: SubstrateSource Natural Lava Gravel is available in two, naturally occurring colors, Volcano Red and Volcano Black. Since this is a naturally produced product, you can expect there to be some variation in the color of the substrate granules. The substrate is screened for a more uniform consistency, but the size and shape of the granules varies. Please view the secondary photo for size reference.

In the Aquarium: The irregular shape of the lava granules helps keep the substrate bed from compacting over time. This promotes healthy rooting of aquatic plants and the stable colonization site for beneficial microbes and bacteria that filter aquarium water.

Application: Our Lava Gravel is packaged and shipped dry and so, friction during shipping or handling may generate small particles or dust. We recommend that you rinse the substrate prior to use. The shipping box and substrate bag are recyclable. Alternative use of this product include use as a bonsai top-dressing, soil amendment, aquarium or pond filter media, and craft projects. Available in 2-pound and 10-pound.

I opted for the black as a base layer under a top layer of ADA aquasoil. It is perfect; looks exactly like the photo. The size of the granules are varied and range from about 2 mm to 6 mm give or take. It is a small bag, so if it's your only substrate you are going to need quite a few bags to fill a 10 gallon (I'm estimating about 6 - 8 bags for a 1.5" depth).
