Salifert reagent test kits are trusted titration-based kits for monitoring key saltwater aquarium parameters such as alkalinity (KH), calcium, magnesium, nitrate and phosphate. They use color-change and color-comparison methods to deliver fast, accurate readings, with most kits providing reagents for roughly 50-100+ tests. The KH/Alkalinity kit, shown here, resolves changes as small as 0.1 meq/L (0.3 dKH) and is for marine use only.
