Controsoil | Planted Aquarium Substrate Soil for Fish Tank

Ultum Nature Systems Controsoil, made in Japan, is a high-quality blend of natural soil and volcanic ash. A good substrate is crucial for a nature aquarium as it supplies essential nutrients for vibrant plant growth and helps maintain balanced water properties by reducing hardness and pH to optimal levels for aquatic plants, shrimp, and most tropical fish.

No Excessive Nutrients

Unlike many other substrates, Controsoil does not cause ammonia levels to spike, which can be harmful to livestock and lead to unwanted algae during the initial stages of setting up an aquarium. Instead, Controsoil provides the right amount of nutrients without excess.

Perfect For All Skill Levels

Controsoil comes in various bag sizes, granule sizes, and colors to suit different preferences and plant types, making it an excellent choice for beginners.

How Much Do I Need?

A general guideline is one 3L bag per 5 gallons or one 10L bag per 20 gallons.

Formula: Tank Length x Tank Depth x Desired Substrate Height (inches) / 60 = Total liters of Controsoil needed
