2Hr Aquarist APTe Aquarium Fertiliser

2Hr Aquarist APTe Aquarium Fertiliser

2Hr Aquarist APTe is a premium Estimative Index (EI) liquid fertiliser, designed to deliver abundant plant nutrition while promoting richer colouration and improved nutrient balance. Inspired by the renowned Estimative Index (EI) method pioneered by Tom Barr, APTe provides a carefully calibrated nutrient profile that supports vigorous plant growth without unnecessary complexity.

Compared to conventional EI fertilisers, APTe features a 2× more nitrate-limiting nutrient ratio to encourage richer plant colours and improved algae control, along with 2× more magnesium to support stronger, healthier plant growth. This balanced formulation makes it an excellent choice for aquascapers looking to maximise plant health and maintain vibrant planted aquariums.

The standard 300ml bottle includes a calibrated dosing pump that dispenses 1ml per press, making daily fertilisation quick, easy, and accurate.
