Aquaforest AF N Boost 250ml is a professional freshwater planted aquarium nitrogen supplement designed to raise nitrate levels and provide aquatic plants with an easily absorbable source of nitrogen. Ideal for planted aquariums, aquascapes, high-light systems and CO2-fertilised tanks, this concentrated liquid fertiliser helps prevent nitrogen deficiency and supports strong, healthy plant growth. Nitrogen is one of the most important macro nutrients for aquatic plants, playing a key role in growth, chlorophyll production, leaf development and overall plant vitality. In fast-growing planted aquariums, especially those with strong lighting, CO2 injection and heavy plant mass, nitrate can become depleted quickly. Aquaforest AF N Boost allows aquarists to raise nitrate accurately and maintain a balanced nutrient profile for lush, healthy aquatic plant growth. Key Features Professional nitrogen supplement for freshwater planted aquariums Provides easily absorbable mineral nitrogen for aquatic plants Helps raise and maintain nitrate levels Supports healthy growth, leaf development and strong green colouration Useful in high-light and CO2-fertilised aquariums Helps prevent nitrogen deficiency in aquatic plants Can help reduce yellowing, chlorosis and stunted growth linked to low nitrate Recommended for use alongside AF Micro, AF PO4 Boost and AF K Boost Concentrated liquid formula for accurate dosing 250ml bottle, ideal for regular planted aquarium fertilisation Product Overview Aquaforest AF N Boost has been developed for freshwater aquarists who need precise control over nitrogen levels in planted aquariums. While nitrate is sometimes reduced heavily in fish-only aquariums, planted tanks require a controlled level of available nitrogen so aquatic plants can grow properly and maintain strong colour and structure. This liquid supplement allows aquarists to increase nitrate in a measured way, helping restore nutrient balance when nitrogen levels are too low. Used correctly, AF N Boost supports stronger plant growth, healthier leaves and better long-term performance in planted aquariums and aquascapes. Benefits for Planted Aquariums Aquaforest AF N Boost helps prevent nitrogen deficiency, one of the most common causes of poor plant growth in freshwater aquariums. Low nitrogen can lead to slow growth, pale leaves, yellowing, chlorosis, reddish discolouration in stems and weak or stunted plant development. By supplying nitrogen in mineral forms that aquatic plants can absorb efficiently, AF N Boost helps plants continue healthy growth and supports better nutrient balance alongside phosphate, potassium and micronutrients. This makes it particularly useful in high-tech aquascapes, heavily planted tanks and aquariums where nitrate is being consumed faster than it is naturally produced. Suitable For Aquaforest AF N Boost 250ml is suitable for: Freshwater planted aquariums Aquascaped tanks High-light planted systems CO2-fertilised aquariums Heavily planted aquariums Fast-growing stem plant layouts Aquariums with low nitrate readings Tanks showing signs of nitrogen deficiency Aquarists using individual nutrient dosing Planted tanks requiring controlled nitrate supplementation This product is designed for freshwater planted aquarium use and should be dosed according to test results and plant demand. How to Use Shake well before use. Dose Aquaforest AF N Boost directly into the aquarium in an area of good water movement, or mix into dosing water as part of a planned fertilising routine. Test nitrate levels before dosing and continue monitoring regularly to ensure nitrate remains within the desired range. Aquaforest recommends using AF N Boost alongside AF Micro, AF PO4 Boost and AF K Boost for a more complete planted aquarium fertilising routine. Dosing Advice Recommended dosage: 10ml per 100 litres of aquarium water raises nitrate by approximately 10mg/l. Aquaforest recommends maintaining nitrate between 10–20mg/l in freshwater planted aquariums. Always test nitrate levels before and during use. Avoid overdosing, as excess nitrogen may contribute to excessive plant growth, weak plant structure and unwanted algae. Do not use with other nitrogen-containing fertilisers unless you are deliberately adjusting a measured fertilising routine. Absorbent filter media such as zeolite and activated carbon may reduce the effectiveness of targeted plant fertilisers, so consider limiting these media when using individual nutrient dosing. When to Use Aquaforest AF N Boost is useful when: Nitrate levels are too low in a planted aquarium Aquatic plants show signs of nitrogen deficiency Plant growth has slowed despite good lighting and CO2 Leaves appear pale, yellow or chlorotic Stems show reddish discolouration linked to nutrient deficiency Maintaining high-light or CO2-injected aquascapes Fast-growing plants are consuming nutrients quickly Using individual nutrient dosing instead of an all-in-one fertiliser Balancing nitrate alongside phosphate, potassium and micronutrients Storage Store in a cool, dry place away from direct sunlight. Keep at room temperature in a tightly closed container. Keep out of reach of children. This product is intended for aquarium use only and is not suitable for consumption. Product Details Product: Aquaforest AF N BoostBrand: AquaforestSize: 250mlProduct Type: Freshwater aquarium plant fertiliserSupplement Type: Nitrogen / nitrate supplementAquarium Type: FreshwaterUse: Raising nitrate levels and preventing nitrogen deficiencyDosage: 10ml per 100 litres raises nitrate by approximately 10mg/lRecommended Nitrate Level: 10–20mg/lSuitable For: Planted aquariums, aquascapes, high-light tanks and CO2-fertilised systems Why Choose Aquaforest AF N Boost? Aquaforest AF N Boost is a practical choice for planted aquarium keepers who want accurate control over nitrate levels. In demanding aquascapes and CO2-fertilised aquariums, plants can quickly consume available nitrogen, leading to deficiency, yellowing and reduced growth. This liquid supplement allows aquarists to correct low nitrate levels precisely and support stronger plant development. Used as part of a balanced fertilising routine, AF N Boost helps maintain healthier aquatic plants, better nutrient balance and more consistent growth. It is especially useful for aquarists who prefer individual nutrient dosing and want to fine-tune nitrogen separately from phosphate, potassium and micronutrients. Recommended For Aquaforest AF N Boost 250ml is recommended for freshwater aquarists maintaining planted aquariums, aquascapes and CO2-fertilised systems where nitrate levels need to be increased or stabilised. It is ideal for correcting nitrogen deficiency, supporting healthy leaf development and maintaining balanced macro nutrition in high-demand planted tanks. Show more
