Red Sea Algae Control Multi Test Kit The Red Sea Algae Control Multi Test Kit is a high-accuracy nitrate and phosphate test kit for reef aquariums, designed to support precise nutrient monitoring and Red Sea NO3:PO4-X dosing. Nitrate and Phosphate Testing for Reef Nutrient Control This multi test kit combines Red Sea's Nitrate Pro and Phosphate Pro testing in one package, giving reef keepers the two key nutrient readings needed to manage nuisance algae, coral coloration and biological nutrient reduction programs. It is especially useful for aquariums using Red Sea NO3:PO4-X or any reef system where nitrate and phosphate trends need to be monitored accurately. Algae Control Multi Test Kit Features Includes high-accuracy nitrate and phosphate tests for reef aquariums. Helps monitor the nutrients that fuel nuisance algae growth. Supports accurate dosing of Red Sea NO3:PO4-X biological nitrate and phosphate reducer. Colour comparator style testing helps improve visual reading consistency. Useful for mixed reefs, SPS systems and nutrient-management programs. Provides separate nitrate and phosphate data so dosing and filtration changes can be made with more confidence. Algae Control Kit Specifications Nitrate accuracy: 0.125 ppm. Nitrate range: 0-64 ppm. Nitrate test count: 100 tests. Phosphate accuracy: 0.02 ppm. Phosphate range: 0-5 ppm. Phosphate test count: 100 tests. Application: reef aquarium nitrate and phosphate monitoring. Application Notes Use this kit when tracking nutrient levels for algae management, coral coloration, feeding adjustments or carbon-dosing programs. Test consistently at the same point in the aquarium's routine, record results over time and make nutrient-management changes gradually rather than reacting to one isolated reading. Official Red Sea Videos Testing Directions Follow the included Red Sea instructions for the specific nitrate or phosphate test being performed. Rinse test vials with aquarium water before use, measure sample volumes carefully, follow timing steps exactly and read results in consistent lighting. Rinse testing equipment with fresh water after use and store reagents closed in the kit case. What's Included 1 Red Sea Algae Control Multi Test Kit.
