ATI Nutrition

System-independent nutrient management

Control nutrients naturally

Nitrate and Phosphate frequently get out of balance and the results are high levels of one and none of the other. Instead of only trying to absorb them, counteract this imbalance by dosing the necessary nutrient your reef craves with ATI Nutrition N and ATI Nutrition P.

Drive growth

Too much of a good thing can turn into a bad thing. If Nitrate and/or Phosphate get too high, it can lead to slow growth, poor coloration, and in extreme cases, coral death. Reduce excess levels of nitrate and phosphate with ATI Nutrition C which will promote the growth of bacteria that will naturally consume these excess nutrients.

Scientific control, simple dosing
