Choosing a quality substrate is an essential part of a nature aquarium as it provides vital nutrients for lush plant growth and helps balance water properties by decreasing the hardness/pH for optimal levels for aquatic plants, shrimp, and most tropical fish.
The general rule of thumb is one 3L bag per 5 gallons or one 10L bag per 20 gallons
One 10L bag will fill a UNS Standard 60U Glass Aquarium with approximately 2” of substrate
[Tank Length x Tank Depth x Desired Substrate Height (inches)] / 60 = Total liters of Controsoil required
