N Boost 500ml – liquid nitrogen

AF N Boost is a liquid nitrogen fertilizer for planted aquariums, intended for keepers who need to correct or maintain nitrogen levels so plants grow evenly and keep a healthy green colour. Nitrogen governs growth, branching and leaf pigmentation, and both shortage and excess cause visible problems, so the dose needs to be measured rather than guessed.

Why it matters

• Dosing is predictable: 10 ml dissolved in 100 l of water raises nitrates by 9.5 mg/l, so the increase can be calculated for any tank volume.
• Symptoms of shortage are clear: stunted growth, chlorosis and yellowing leaves, progressing to browning, signal that nitrogen is limiting.
• Mineral forms: the product supplies nitrogen as nitrate and ammonium, the two forms plants take up in aquariums.
• Target range: the recommended nitrate level for a planted tank is 10-20 mg/l, which gives a reference point for when supplementation is needed.

What it works with

The fertilizer is designed for planted freshwater aquariums, where nitrogen is dosed alongside other nutrients. The manufacturer recommends using it together with AF Micro, AF PO4 Boost and AF K Boost. Do not combine it with other nitrogen-containing products, as this raises the risk of over-fertilizing plants and algae blooms.
