Aquarium Soil for 20 Long–35 Gallon Planted Tanks, Complete Natural Substrate with Supplement for Low-Tech Setups

Build a lasting foundation for a planted aquarium with this complete soil medium, portioned for 20 Long to 35-gallon tanks. The soil and pre-included supplement create a microbially active root zone that feeds roots for years, supporting a stable, low-tech aquarium routine.

Layer the soil beneath pool filter sand, plant heavily from the start, and fill the aquarium slowly. This setup supports rooted stems, swords, and crypts, while rhizome plants such as Anubias can be mounted on wood or rock.

Key Features

• Long-term natural fertility feeds plant roots for years, reducing the need for bottled fertilizers or added CO2 in everyday care.
• The matched supplement comes pre-included with the soil, creating a complete root-zone base without a separate supplement purchase.
• Safe use around fish, shrimp, snails, and plants makes the substrate suitable for a varied planted aquarium community.
• Its stable, deep-substrate foundation suits low-tech aquariums where biological activity supports the planted setup.
• Stems, swords, and crypts can be planted into the substrate, while Anubias can be mounted on hardscape for a flexible aquarium layout.
