This Fluval Plant Gro Plus is an improved version that is six times stronger in concentration that their previous supplement. This all-in-one micro nutrient is enriched with iron to help promote vigorous growth, deep colouration and a strong root system for freshwater aquatic plants.
Fortified with Vitamin B to enhance a long-term colour and health, this super formula treats 45l with just 1ml. The Plant Gro Plus is designed to prevent mineral deficiencies as well as promoting disease resistance, and is completely safe for all fish and aquarium inhabitants, including invertebrates.
Ideally, this should be used weekly, as plants naturally deplete micro-nutrients over time and tap water is often lacking of them. For best results, use in conjunction with an Iron Test Kit, to ensure you're maintaining an optimum concentration of 0.3 mg/L of iron within the tank.
