“I knew certain things like potassium and magnesium were elevated in my reef, and the test was consistent with my Red Sea and Salifert kits. But without comparison to a certified standard/method it's hard to know accuracy. My results showed ppb levels of some heavy metals, which concerns me. Ended up buying some Cuprisorb just in case, but haven't used it yet since the SPS and other corals are growing ok.”
“Easy to ship and get results back quickly better than the other icp test I’ve used”

TDS Meters Are Not Precise Enough
Traditional TDS meters don’t measure trace elements in water — only ppm. Harmful toxins to corals and your health are traced in ppb. Using a test that can detect low-ppb allows us to measure any toxic elements that could accumulate in our system before mixing the salt water.
ICP analysis uses a mass spectrometer to achieve the highest degree of accuracy. It measures the mass-to-charge ratio of the ions, offering insightful and precise results that exceed traditional methods.
