The ATI Element Chromium is a precise liquid supplement designed to maintain optimal chromium levels in reef aquariums. This product helps to stabilize and enhance the biological processes within marine environments by providing essential trace elements that may be depleted over time or absent from regular water changes. To use, simply add 1 mL per 100 liters of water to increase chromium levels by 1 µg/L, with a maximum daily dose of 0.5 mL per 100 liters. The ATI Element Chromium is compatible with the Advanced Aquaristics Systems (AAS) ICP testing system, ensuring accurate monitoring and adjustment of trace element concentrations in reef tanks. This solution comes in a convenient 150 mL bottle containing 15,000 µg of chromium.
