Makro Spezial NPK Soil

Aqua Rebell Makro Spezial NPK Soil was specially developed to meet the needs of modern planted aquariums with active soil substrates and ensures a balanced supply of the essential macronutrients nitrate, phosphate, and potassium. The special formula is nitrogen-rich, phosphate-limited, and potassium-enriched—ideal for optimally supporting the natural nutrient dynamics of soil aquariums without unnecessarily disrupting the biological balance. As a result, the fertilizer promotes healthy, vigorous, and at the same time compact plant growth and helps reliably close typical nutrient gaps.

Thanks to its balanced formulation, Makro Spezial NPK Soil is ideal for the long-term care of aquascapes and planted aquariums. Aquatic plants benefit from a constant supply of nutrients, developing intense colors, sturdy shoots, and vigorous growth. At the same time, the risk of unnecessary nutrient excesses remains low. The fertilizer can also be used in aquariums without soil if a controlled, phosphate-limited macronutrient supply is desired. Under these conditions, plants often grow particularly compact, healthy, and harmoniously.

The ready-to-use liquid formula allows for easy and precise dosing, making the fertilizer ideal for practical weekly fertilization. For optimal results, we also recommend using a micronutrient fertilizer to provide iron and trace elements, such as Mikro Spezial Flowgrow.

Recommended dosage (per 50 liters of aquarium water)

• High light + CO₂ supplementation: 1 ml daily
• Low light + CO₂ supplementation: 0.5 ml daily
• Without CO₂ supplementation: 1–2 ml weekly

Note: These figures are for guidance only. Depending on the specific conditions of your aquarium, the dosage can be adjusted to achieve optimal results.
