Special characteristics of Black Earth Premium:
1) Does not release ammonia
Fertile substates 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.
2) 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.
3) 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.
4) High density granules
The Black Earth Premium formula creates granules with higher density. This translate to the granules holding down plants better
5) 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 is optimal for keeping aquatic plants and most freshwater fish.
Available sizes and granule types
Black Earth Premium is available in 9-liter (sufficient for a 20 gallon tank) bags. With two granule sizes to choose from: Normal and Extra Fine.
