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.

ATI Essentials Mixed Reef is a two-in-one solution designed for mixed reef aquariums. Designed for enthusiasts who want to put an end to complicated mixing, this ultra-concentrated kit contains two ready-to-use 2.7L containers. It provides both major elements (such as calcium, magnesium or alkalinity) and essential trace elements (iodine, iron, zinc, etc.) without the risk of accumulation.

All without the hassle: same dosage for both parts. Ideal for well-stocked aquariums and suitable for all levels, from beginner to expert.

Thanks to its mineral-only formulation, it stabilizes the pH at a higher level, which is ideal for the most sensitive corals. It provides all the essential major and trace elements, without accumulation. And as always with ATI , it is the result of thousands of ICP analyses for unparalleled accuracy. Simple to dose, ultra-effective and designed for demanding aquarists.
ATI Essential Phospho was formulated to address an often underestimated problem in reef aquariums: phosphate deficiency . Yes, too much phosphate is a problem. But too little? That's just as dangerous. Below 0.03 mg/l , corals, especially SPS corals, can suffer, even rapidly losing tissue. With Essential Phospho, a stable level is maintained within the optimal range of 0.03 to 0.1 mg/l, ideal for balanced growth without promoting unwanted algae.
This supplement is part of the ATI Essentials system , a comprehensive approach to managing key seawater parameters. Working in tandem with the other components in the range, it ensures a consistent environment without sudden fluctuations. And it's not just for emergency correction: it can also be used routinely to maintain optimal phosphate levels.
The dosage is straightforward: 1 ml per 100 liters increases the phosphate level by 0.015 mg/l . The bottle contains enough to fine-tune the levels without risk of overdosing. In case of a pronounced deficiency (phosphate dropping to zero after a few hours), it is even possible to divide the intake throughout the day to maintain the desired level.
Whether you have a sparsely populated aquarium or a highly filtered system with a refugium, carbon, and resins, Essential Phospho gives you the control to manage phosphate concentration to the exact degree . And that makes all the difference in the long run: more colorful corals, better growth, and an overall more balanced tank.
Phosphorus is essential fuel for reef life. It supports cell synthesis, tissue formation, and plays a vital role in coral metabolism. Without it, corals slow down, decline, and sometimes even die, despite seemingly perfect parameters. This is where Essential Phospho makes all the difference : it fills that small gap that can sometimes be the key difference between a stable tank and a thriving reef.
With its 500ml bottle containing 750mg of phosphate , there's more than enough to cover needs for several weeks, or even months depending on the tank size and consumption. It's a simple, effective, and essential safety measure for any serious aquarist.
