Here’s a complete breakdown of Kenko Fusion Prime specifically tailored for low-light, slow-growing plants like Anubias, Cryptocoryne, and aquatic ferns (e.g., Java Fern, Bolbitis).

1. Why These Plants Have Different Needs

• Slow growers → absorb nutrients gradually, so they don’t need heavy dosing.

• Rhizome or root feeders → Anubias & ferns take most nutrients from water; Cryptocoryne prefers some root feeding.

• Low-light adaptable → Less demand for nitrogen & phosphates compared to high-light stem plants.

• Algae risk → Overdosing in slow-growing tanks can cause algae because uptake is slow.

2. What Kenko Fusion Prime Does for Them

• Supplies trace elements (iron, manganese, zinc, etc.) to keep leaves green and healthy.

• Provides macronutrients (NPK) in low to moderate amounts, ensuring steady but not explosive growth.

• Keeps nutrient levels consistent so plants don’t show deficiency symptoms (yellowing, holes, melting).

3. Key Nutrients & Why They Matter

4. Dosing Approach

• Frequency: 1–3 times a week is usually enough.

• Amount: Half of what a high-light tank needs — slow growers don’t consume as much.

• Method: Dose directly into the water column.

• Extra for Cryptocoryne: Occasional root tabs can speed recovery after transplant or melting.

5. Tips for Best Results

1. Steady, not heavy – Consistency beats large infrequent doses.

2. Balance with lighting – Moderate lighting reduces algae risk.

3. CO₂ optional – These plants thrive without injected CO₂, but growth will be a bit faster with it.

4. Watch the leaves – New leaf health tells you if nutrients are balanced.

5. Water changes – 25–30% weekly helps avoid nutrient build-up.

💡 Pro Tip: For a mixed Anubias–Crypt–Fern tank, you can use Kenko Fusion Prime plus root tabs under the crypts every 2–3 months. This covers both water-column and root feeding without overloading nutrients.
