Detailed product description

2Hr Aquarist APT 3 – Complete is a high-precision, full-spectrum all-in-one fertilizer engineered for demanding planted aquariums. Developed by Dennis Wong, APT 3 is built for aquascapes running medium to high light, consistent CO₂ injection and a goal of achieving compact growth, vibrant coloration and predictable long-term performance.

How APT 3 works

APT 3 provides all essential macro and micro nutrients (NO₃, PO₄, K, Fe, Mg, Mn, Zn, B and more) in ratios that support strong plant metabolism without nutrient accumulation or imbalance. This results in improved CO₂ uptake, stronger photosynthesis and more efficient cell division.

Balanced NO₃:PO₄:K ratio

The formula is based on actual plant demand rather than theoretical limitations. APT 3 is ideal for:

  • medium to high-light planted tanks
  • CO₂-enriched systems
  • densely planted aquascapes
  • demanding stem plants and fast growers

Superior photosynthesis & enhanced red pigmentation

The chelated iron and micro nutrient blend in APT 3 is optimized for high-light environments. This increases the production of anthocyanins, the red pigments responsible for rich coloration in species like Rotala, Ludwigia and Alternanthera. Plants stay compact, healthy and richly colored.

Macronutrients – the engine of growth

  • Nitrate (NO₃): drives new tissue formation and strong green growth.
  • Phosphate (PO₄): essential for ATP, energy transfer and rapid metabolism.
  • Potassium (K): improves nutrient transport and tissue strength.

Micronutrients – the fine tuning

A precise blend of chelated iron, manganese, zinc, boron, copper and molybdenum ensures strong enzyme activity, pigment formation and chlorophyll development.
