Easy Life Pro Fito, 500 ml - Highly concentrated universal plant food for strong, healthy plant growth. Extremely economical to use. Contains no nitrates. The optimal composition of ProFito provides plants with everything they need for unhindered, strong, and lush growth. This highly concentrated, all-in-one universal plant food includes Iron, Potassium, and Manganese. This perfect combination ensures strong, healthy, and lush plant growth in your tank. ProFito promotes the production of cytokinins, which stimulate cell division, leading to wider leaves and more intense coloration. It also improves and consolidates the biological balance within the aquarium for maximum stability. It contains no nitrates or phosphates, which can encourage algae growth. At a dosage rate of 10ml per 100l, it is an economical plant food. Ideally, use 10ml per 100l once a week, or a 1/7th dose daily. The product color may vary, which is normal. For the first few weeks, adjust the dosage to find the right levels for your aquarium by observing the youngest leaves of the plants. If they are light green, increase the dose. If algae appear or plant growth enhancement ceases, reduce the dose slightly. Fast-growing plants also help reduce algae levels.
