ADA's new BOTTOM PLUS is a successor product of Iron Bottom and Multi Bottom.
This product is enhanced with nitrogen and iron, which become depleted in aquarium substrate over time as plants use available nutrients. It promotes leaf color of the plants which actively absorb nutrients through their roots. BOTTOM PLUS is mainly made of the same natural soil as the Aqua Soil products, and will completely break down in the substrate.
*Package of each Solid Substrate Nutrient will be renewal.
