Marine ICP testing (Inductively Coupled Plasma) is a laboratory-grade water analysis that measures dozens of elements in your saltwater – from the big three (calcium, magnesium, alkalinity-related ions) to trace and even unwanted contaminants like metals. By sending a small water sample to the lab, you get a detailed report showing exactly what’s high, low or out of balance, along with correction recommendations. Used alongside regular home test kits, Marine ICP makes it far easier to fine-tune your dosing, spot hidden issues and keep your reef running in a safe, stable “sweet spot” for long-term coral health and colour.
