Because fresh water plants require a full range of nutrients to grow and be vigorous (nutrient health), PlantGro Iron Enriched Fertilizer (0.3 - 0.18 - 0.95) will help achieve this goal. Thriving aquarium plants rapidly deplete normal levels of nutrients and minerals within the closed system of the aquarium. PlantGro intensifies plant colors by enhancing intracellular enzymatic reactions. Rapid and well balanced growth is the visible result. This freshwater fertilizer is non-toxic to fish and will not cause problems with other inhabitants within the aquarium. Treats 235 US gallons. Shipping-Weight: 0.4 lb |
