Complete Marine Testing Solution
Instead of purchasing five individual test kits, the Red Sea Marine Care Multi Test Kit combines the core parameters needed for general marine aquarium maintenance into one convenient package.
For reef aquariums with growing corals, additional testing of calcium, magnesium, phosphate, and other reef-specific parameters may also be recommended.
