SOSEI CAPS – soil fertiliser, 80 pieces

YOKUCHI SOSEI CAPS are root-zone fertilizer capsules for planted aquarium substrates. They suit aquarists who want to feed rooted plants at the source and keep a fertile substrate over a long period without dosing the water column.

Why it matters

• Nutrients at the root level: The capsules place a mineral complex close to the roots, where rooted plants take up nutrients.
• Substrate ion-exchange support: The product is designed to help the substrate maintain its ion-exchange properties, which supports its fertility over time.
• Organic biostimulants: Each capsule combines minerals with organic substances that act as biostimulants.
• Stable planted layouts: Regular application is intended to keep the substrate fertile and help planted arrangements remain stable in the long term.

What it works with

The product is intended for planted aquariums with rooted plants growing in substrate. Dosing is based on placing capsules at a set spacing near the root zone, so the number of capsules needed depends on the size of the planted area. It is applied to the substrate, not to the water.
