Instant Ocean Master Test Kits
Instant Ocean aquarium test kits make saltwater testing easier than ever before for the beginning hobbyist as well as the experienced aquarist. The one piece color chip comparator is easier to use than any other saltwater test kit available. The durable wide-mouth holder has more room for adding the test chemicals and is more stable to prevent spilling.
