Specifically designed for saltwater and reef aquariums, each batch is verified by ICP analysis for reliability and precision. Test Eight Key Parameters Quickly check eight essential saltwater parameters: alkalinity (KH), calcium, magnesium, nitrate, nitrite, pH, specific gravity, and iron. ICP Verified Results Every batch is verified through ICP testing for trusted accuracy, giving hobbyists confidence in every reading. Fast and Convenient Get accurate results in 60 seconds without complicated reagents or glass vials. Just dip, wait, and compare. Formulated for Saltwater Each strip is formulated for the unique chemistry of saltwater environments, ensuring consistent, reef-relevant results that other test strips simply can’t match.
