  • 【 COMPLETE PLANT FERTILISER FOR AQUASCAPERS】: Plantus is a complete fertiliser for your freshwater aquatic plants. It contains all macro and micronutrients needed for optimum plant health and growth.
  • 【SUITABLE FOR ESTIMATIVE INDEXING】: The formulation of Plantus is based on the Estimative Index concept for dosing, where plant nutrients and vital trace elements are provided in abundance. Plant growth is limited by the least available nutrient, so by providing these in excess, plant growth is maximised. The unused nutrients are then removed from the system during a water change.
