Dymax root supplements directly provide essential nutrients to plant roots, promoting healthy growth of rosette plants, stem plants, and root feeders. They should be inserted 1-2 inches below the substrate surface, with 4 inches of space between each tablet. For best results, use 2-3 tablets per plant in the root development area, repeating every 2-3 months. Highlights include improved plant growth and stronger root systems, increased resistance to disease and algae, and maintenance of proper nutrient levels in the aquarium. Each package contains 50 tablets.
