Seachem Aquavitro Freshwater Synthesis Nitrogen Supplement

Aquavitro Synthesis delivers a concentrated nitrogen supplement (nitrate and ammonium) for planted aquariums where nitrogen is the limiting nutrient. In a heavily planted, high-light tank with CO₂ injection, nitrogen is consumed so fast that your fish load may not keep up with demand — especially in a lightly stocked display with fast-growing carpeting or stem plants. Synthesis lets you dose nitrogen independently at the rate your tank actually needs rather than relying entirely on fish waste as your nitrogen source.
