PHAT FUNDAMENTAL PLANT FERTILISER
Effortless Nutrition. Everyday Growth. All Colour.
For planted tank keepers who want simplicity without sacrificing results—PHAT FUNDAMENTAL is your go-to, all-in-one aquarium plant fertiliser. Designed for low to medium light tanks, non-CO₂ or lightly injected setups, and slower-growing aquatic plants, this formula fuels your scape without overcomplicating your routine.
With a clean dose of potassium and essential micronutrients, PHAT FUNDAMENTAL supports healthy leaf development, vibrant color, and stable long-term growth. Whether you're running a jungle-style layout, a beginner-friendly nano tank, or just want to keep things low-key—this is the perfect foundational fertiliser for your aquatic plants.
