NPK All-in-One Macro Solution 1L

The one-litre economy size of this NPK all-in-one macro solution is designed for hobbyists with larger planted tanks or multiple aquariums who dose regularly and want to reduce cost per litre. The formula is identical to the 500ml version — a balanced nitrogen, phosphorus, and potassium blend suited to a wide variety of aquatic plants.

Larger tanks with heavy plant mass consume macro nutrients rapidly, particularly in CO2-injected setups with high lighting. Buying in the larger format ensures a continuous supply without frequent restocking and reduces packaging waste.

The solution is crystal clear, does not tint the water, and remains stable at room temperature for at least 18 months. It pairs seamlessly with any trace element or micro-nutrient solution for a complete two-part fertilisation programme.
