ADA Bottom Plus is a nutrient-rich substrate additive from Aqua Design Amano designed to replenish essential nutrients in the aquarium substrate that are gradually depleted over time as plants grow. It is the successor to ADA’s Iron Bottom and Multi Bottom formulations, enhanced with key elements like nitrogen and iron to support healthy plant root uptake and vibrant foliage.

Key Features & Benefits:

Balanced Nutrient Supply: Each stick contains a carefully formulated blend of nutrients — including nitrogen and iron — that are essential for aquatic plants, especially those that absorb nutrients primarily through their roots.
Supports Root-Feeding Plants: Ideal for rooted species (e.g., Cryptocoryne, Echinodorus, and other nutrient-hungry plants), helping promote strong root development and enhanced growth.
Enhances Leaf Color: By supplying nutrients that can become limited in older substrates, Bottom Plus encourages healthier, more vibrant foliage.
Slow-Release Formula: The sticks dissolve gradually in the substrate, providing a steady long-term nutrient release without disturbing the aquarium layout or clouding the water.
Natural Soil Base: Made primarily from the same natural soil materials used in ADA Aqua Soil products, the sticks fully integrate into the substrate and eventually break down as they release nutrients.

How to Use:
Insert one Bottom Plus stick approximately every 15 × 15 cm (~6 × 6 in) of substrate, placing it as deep and near plant roots as possible for best nutrient delivery. It can be added during initial setup or later in established aquariums when nutrient levels decline.

Perfect For:
Long-term planted aquariums
Mature tanks where substrate nutrients are depleted
Layouts with larger or dense plant growth
Enhancing plant vigor and coloration
