Thrive™ is designed to keep your aquatic plants vigorous and beautiful all season long. Thrive™ pellets will feed potted aquatic plants all season long. Simply use one tablet for every gallon of soil each month during the growing season. Push one tablet one finger deep into the soil, 3" from the crown of the plant. Press soil around the inserted tablet for best results. It is always a good idea to feed plants every two weeks when the water temperature raises above 75°F.
