Eco‑Complete™ Planted is now Eco-Planted™. Same great product but with a new name. Eco-Planted™ Black’s secret lies in rich basaltic volcanic base which contains iron, calcium, magnesium, potassium, sulfur plus over 25 other elements to nourish your aquatic plants.

No artificial dyes, paints, or chemical coatings. Eco-Planted™ Substrates incorporate highly porous grains for optimum diffusion performance and live Heterotrophic bacteria to rapidly convert fish waste into natural food for your aquatic plants. It establishes a natural biological balance which makes cycling a new aquarium faster and safer.
