API Saltwater & Reef Aquarium Master Test Kits - 550 Saltwater & Reef Water Tests

The API SALTWATER MASTER TEST KIT and API REEF MASTER TEST KIT complement each other to help aquarium owners accurately monitor and maintain safe water conditions in saltwater reef aquariums. The SALTWATER MASTER TEST KIT contains 6 bottles of testing solution, 1 color card, and 4 test tubes with caps to monitor high range pH, ammonia, nitrite, and nitrate levels across 550 tests. The REEF MASTER TEST KIT contains 7 bottles of testing solution, 2 color cards, and 4 test tubes with caps to measure calcium, carbonate hardness, phosphate, and nitrate levels. Used together, these 11 bottles of test reagents, 3 color cards, and 8 total test tubes can prevent invisible water quality issues like algae blooms and fluctuations in pH that can stress reef inhabitants. Aquarium owners simply fill the test tubes with water, add the appropriate test drops, and compare results to the color cards to modify water conditions if unsafe levels are detected.
