2Hr Aquarist APT 1

APT 1/Zero by 2HR Aquarist is a comprehensive aquarium fertilizer tailored for tanks with a substantial fish population and relatively few aquatic plants. In such setups, the natural accumulation of nitrates and phosphates is higher due to fish food remnants and fish waste.

When establishing a new aquarium with a soil substrate, using APT 1/Zero in the initial three months can be advantageous. During the initial phase, used soil releases sufficient nitrates into the water.

By employing this phosphate and nitrate-free fertilizer, you can prevent nutrient overabundance in aquariums teeming with fish or recently set up with soil. The primary components of this fertilizer are potassium, iron, and magnesium, complemented by a well-balanced mineral composition. This formulation promotes the vibrant growth and vivid coloration of aquatic plants.

With APT 1/Zero, no additional fertilization is needed, as it serves as a comprehensive fertilizer.
