Cal Aqua Labs – Black Earth Premium
$42.95 – $51.95
Black Earth Premium is Cal Aqua Lab’s flagship substrate and is unlike any other soil substrates on the market. It is developed and manufactured from the ground up in our own laboratory backed by years of cumulative research and testing. The end result is a highly-advanced, highly-fertile substrate that supports long term lush, healthy plant growth.
Special characteristics of Black Earth Premium:
1) Highly fertile
Black Earth Premium is formulated for maximum fertility. Made from natural fertile soil rich in humic acids, it contains a large amount of essential plant nutrients such as Nitrogen, Potassium, Phosphorous, and trace elements such as calcium, magnesium, iron, and manganese.
2) Super clean
The first thing users will notice about Black Earth Premium is how clean it is right out-of-the-bag.
Unlike other substrates where dust and debris are a common part, our substrate is specially manufactured to contain as little foreign materials as possible.
As a result, water remains clear starting from the moment the aquarium is filled.

3) Harder granules = Longer substrate lifetime
CAL AQUA LABS developed an advanced process for the production of Black Earth Premium that results in virtually dry granules that are much harder than other substrates while maintaining maximum fertility.
Because of this, they suffer significantly less breakage during transportation and setup, resulting in prolonged lifetime of the substrate.
