An essential supplement to prevent phosphate deficiencies
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.
Simple dosage and custom adjustment according to your container
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.
An often overlooked element… but vital for a healthy reef
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.
