How to use the product
Premium Fertiliser is added each week when changing the water. A flask is used to ensure an accurate dosage. The fertilizer is forced up into the fertilizer chamber by a single press on the flask. We recommend 5 mL per 50 L water per week, but recommend that this is set in accordance with plant requirements. For example, light leaves often indicate lack of nutrients.

I’ve been using this fertilizer for three months in my fish tank with 20+ fish. The plants have grown steadily without any fish stress. The dosing is easy with the flask, and I can see the leaves turning greener. No algae issues either. Good balance for plant needs without harming fish.

Works well for my low-growing plants. I use 5 mL per week in a 100L tank. The leaves are healthier than before. It’s a simple process and the iron helps with color. I’d use it again if I had more plants.
