ATI 's Essential Nitro is a complete nitrogen supplement designed to prevent nitrogen deficiencies in reef aquariums. Unlike traditional nitrate-based products, it offers a formula enriched with urea, ammonium, vitamins, and amino acids that are easily absorbed by corals. This nutritional balance boosts growth, vitality, and color intensity by promoting chromoprotein formation. It integrates perfectly into the ATI Essentials system (SPS or Mixed Reef) and is suitable for all nutrient-deficient tanks. With Essential Nitro, polyps expand, and tissues gain density.

Essential Phospho from ATI is a liquid supplement designed to prevent phosphate deficiencies in marine aquariums. An integral part of the Essentials system , it ensures healthy growth of coral biomass, particularly in hard corals (SPS/LPS). A significant drop in phosphate can lead to rapid tissue loss in corals, a sign of imbalance. Thanks to its precise formula, Essential Phospho allows you to adjust and maintain the phosphate concentration within the ideal range of 0.03 to 0.1 mg/l . Easy to dose, effective, and safe, it's the product to keep on hand to guarantee a stable tank without any hassle.
Essential Nitro is much more than just a nitrate-based additive. Its complex and balanced formulation includes several sources of nitrogen, both organic and inorganic: urea, ammonium, amino acids, vitamins
In ultranutrient-low nitrogen (ULNS) reef systems, where nitrate levels are often close to zero, nitrogen quickly becomes a limiting factor . Corals then struggle to grow despite perfect physicochemical conditions. By addressing this deficiency in a controlled and targeted way, Essential Nitro provides the "fuel" necessary for healthy and sustainable growth.
One of the major advantages of ATI Essential Nitro is its visible effect on coral coloration . By stimulating the formation of chromoproteins , this supplement enhances natural pigments and intensifies existing hues. Corals appear brighter, more vibrant, with a particularly noticeable "glow" effect in blue light. And because the formula also contains vitamins and amino acids , it provides overall support for coral metabolism, improving their resistance to stress.
Used regularly, Essential Nitro becomes an effective management tool for anyone looking to stabilize their reef aquarium , especially SPS and Mixed Reef tanks. You'll see well-opened polyps, regular growth, and a visibly more vibrant reef.
The recommended base dose is 0.5 ml per 100 liters per day. This dosage can be adjusted according to the specific needs of the tank: population, measured levels, and coral behavior. In all cases, it is advisable to start small and increase gradually, carefully monitoring nitrate and phosphate levels, as well as the corals' reaction.
Essential Nitro integrates perfectly into the ATI Essentials SPS or Mixed Reef system, but can also be used alone as a targeted corrector for a deficient tank. It is particularly useful in ULNS or highly filtered aquariums , where nitrogen is often depleted too quickly.
ATI Nutrition Products are ideal in addition to Essentials Pro products, they contain organic compounds and nutrients essential for the balance of the marine aquarium and corals
