Dennerle NPK Booster is a specialized liquid macronutrient fertilizer formulated specifically for heavily planted, high-demand aquascaping aquariums. It provides an immediate injection of Nitrogen (Nitrate), Phosphorus (Phosphate), and Potassium, along with added Magnesium.

Why It Is Used:

In standard community tanks, fish food and waste generate plenty of nitrate and phosphate naturally. However, the dynamic changes entirely in high-tech environments. This booster targets setups with:

• Dense Vegetation: Plenty of fast-growing plant species.
• High-Tech Gear: High-intensity lighting and heavy CO₂ injection.
• Low Bioload: Environments primarily holding low fish stocks, shrimp, or snails.
• Frequent Maintenance: Routines that involve large (30% to 50%) weekly water changes.

Without macronutrient supplementation in these environments, fast-growing plants quickly exhaust available nutrients, resulting in stalled growth, pale leaves, and opportunistic algae outbreaks.

Dosage Guidelines:

The manufacturer recommends a baseline dosage of 10 ml per 100 litres of aquarium water weekly. This standard dose changes your water column values by adding exactly:

• Nitrate (NO₃): 5.0 mg/L
• Phosphate (PO₄): 0.4 mg/L
• Potassium (K): 2.5 mg/L

Critical Target Levels & Testing:

• Test Before Initial Use: You should always measure your nitrate levels using a kit like the Dennerle Water Test 6in1 before adding this product.
• Avoid Overdosing: Blindly dosing macronutrients when your levels are already high can easily trigger severe algae blooms.
• Complementary Nutrients: This booster only covers macronutrients. To satisfy your plants’ full dietary needs, you must pair it with a micronutrient and iron supplement, such as Dennerle Plant Care Pro.
