API Reef Master Test Kit API Reef Master Test Kit is a reef aquarium liquid test kit that measures calcium, carbonate hardness, phosphate, and nitrate, helping reef keepers monitor the key levels that affect corals and reef invertebrates. API Reef Master Test Kit for Calcium KH Phosphate and Nitrate Reef aquariums require more than basic fish-only water testing. Corals, crustaceans, mollusks, and encrusting algae use calcium and rely on stable carbonate hardness, while phosphate and nitrate can influence algae growth, hard coral performance, and overall reef water quality. Reef Water Testing for Coral Growth pH Stability and Nutrient Control Measures calcium, carbonate hardness, phosphate, and nitrate. Designed for reef aquarium water testing. Helps monitor calcium used by corals, crustaceans, mollusks, and coralline algae. Tracks carbonate hardness to support pH stability and reef mineral balance. Measures phosphate that can contribute to algae blooms and affect hard coral growth. Measures nitrate from fish waste and organic buildup. Complements the API Saltwater Master Test Kit, which focuses on high range pH, ammonia, nitrite, and nitrate. API Reef Master Test Kit Use and Marine Aquarium Notes Product type: liquid reef aquarium master test kit Parameters tested: calcium, carbonate hardness, phosphate, and nitrate Use for: reef aquariums and marine systems requiring reef-specific water testing Best fit: coral tanks, reef invertebrate systems, and aquariums using calcium or alkalinity supplementation Use results before adjusting calcium, alkalinity, nutrient export, phosphate media, or water-change routines. Rinse test tubes after every use and store reagents capped tightly. API Reef Master Test Kit Directions Select the reef parameter being tested and read that test’s specific instructions first. Rinse the test tube and fill it with aquarium water to the required line. Add the listed test solutions in the correct order and amounts for the selected test. Cap and mix the sample as directed by the instruction booklet. Wait the required development time or complete the titration endpoint depending on the test. Compare the result to the proper colour card or calculate the reading according to the instructions. Do not pour test contents back into the aquarium, and rinse test tubes immediately after use.
