What is the difference between API SALTWATER MASTER TEST KIT and API REEF MASTER TEST KIT?. Both of these kits may be uséd in marine aquariums; however, the API SALTWATER MASTER TEST KIT will allow you to test for ammonia, high range pH, nitrite, and nitrate in your tank, while API REEF MASTER TEST KIT tests for calcium, carbonate hardness, phosphate, and nitrate – all of which need to be maintained at appropriate levels for a thriving reef aquarium.
