2Hr APT1 Zero

2Hr Aquarist APT 1/Zero

APT 1/Zero by 2Hr Aquarist is a comprehensive fertiliser formulated for aquariums with a high fish population and fewer aquatic plants. It is ideal for tanks where nitrates and phosphates are already present due to fish waste and leftover food. APT 1/Zero is nitrate- and phosphate-free, making it perfect for preventing nutrient oversupply while still promoting healthy plant growth and vibrant colouration.

This fertiliser is especially beneficial for new setups using aquasoil, where ample nitrate is released in the first few months. With a precise balance of potassium, iron, magnesium, and trace elements, APT 1/Zero supports lush, algae-free aquascapes without the need for additional dosing.
