Black Earth Premium is a fertile soil substrate made from natural soil rich in natural nutrients and minerals. It is developed from the ground up and is the result of years of cumulative research and testing. The end result is a highly-advanced, highly-fertile substrate that does not leach harmful ammonia into the water column.

Does not release ammonia

Fertile substrates tend to leach high levels of ammonia into the water column during the initial weeks of setup. This may be harmful to sensitive inhabitants, making users wait for long periods of time before safely introducing aquatic fauna into their tank. Although Black Earth Premium is highly-fertile and rich in organic nutrients, our advanced production process locks the ammonia inside the substrate. This assures that most of the nutrients remain within the substrate for the plants, and not washed away by water. As a result, the substrate remains fertile longer. This also makes your aquarium less prone to algae outbreaks, as well as keeps the aquatic inhabitants safe and eliminates long cycle times.

Advanced production process = Natural granules that extend substrate lifetime + better preserved nutrients

Cal Aqua Labs developed an advanced process for the production of Black Earth Premium that results in cohesive granules that are not brittle under prolonged submergence. As a result, they suffer significantly less brittle fractures and prolong the lifetime of the substrate. Our unique production process also better preserves the natural nutrients within the soil than conventional methods.

Polished, crystal clear water

Special ingredients blended into Black Earth Premium have the ability to capture and bind small colloidal particles in water. As a result, the substrate doubles as another biological and mechanical filtration unit with massive surface area. This results in amazingly polished, crystal clear water.

High density granules

The Black Earth Premium formula creates granules with higher density. This translate to the granules holding down plants better.

Creates slightly acidic water conditions

Black Earth Premium is made from natural, highly-fertile earth which is rich in humic and fulvic acids. As a result, it creates slightly acidic water conditions which are optimal for keeping aquatic plants, shrimps and most freshwater fish.
