Here’s everything you need to know about Kenko Fusion Pro All-in-1 Fertilizer for Aquariums — the type that provides complete plant nutrition in a single product.

1. What It Is

Kenko Fusion Pro is an All-in-1 Aquarium Fertilizer is a liquid or powder formulation that contains all the essential nutrients aquarium plants need — both macronutrients and micronutrients — in one convenient mix.
It eliminates the need to dose separate bottles for nitrates, phosphates, potassium, and trace minerals.

2. Main Nutrients Inside

Macronutrients – Needed in larger amounts:

• Nitrogen (N) – Promotes leaf and stem growth.

• Phosphorus (P) – Supports root development and flowering in some aquatic plants.

• Potassium (K) – Strengthens plant cell walls and helps nutrient transport.

Micronutrients – Needed in smaller amounts:

• Iron (Fe) – Vital for leaf color (especially red plants).

• Magnesium (Mg) – Important for chlorophyll production.

• Calcium (Ca) – Helps with cell structure.

• Boron (B), Manganese (Mn), Zinc (Zn), Copper (Cu), Molybdenum (Mo) – Support various metabolic and enzymatic processes.

3. Benefits

• Convenience – One bottle covers everything.

• Balanced dosing – Reduces risk of over/under-dosing specific nutrients.

• Healthier plants – Consistent growth, better coloration.

• Less guesswork – Good for beginners and low-maintenance aquariums.

4. How to Use

• Shake well before each use (nutrients can settle).

• Dose according to tank size, plant density, and light level (usually mentioned on the bottle).

• Common routine: Dose daily for high-tech tanks with CO₂, or 2–3 times per week for low-tech setups.

• Always pair with regular water changes to avoid nutrient build-up.

5. Things to Watch Out For

• Algae growth – Overdosing nutrients without enough plant uptake can fuel algae.

• Fish load – If you have many fish, they already produce some nutrients (especially nitrogen and phosphorus), so you might need less fertilizer.

• Light & CO₂ balance – Fertilizers alone won’t make plants thrive; they need enough light and carbon dioxide.

💡 Pro Tip: For heavily planted, high-light tanks with CO₂, all-in-1 dosing works best when paired with consistent trimming and weekly 30–50% water changes to keep nutrients in balance.
