Red Sea test kits are very accurate liquid tests. Remember that these tests are only as accurate as the person running the test. For best results make sure follow instructions closely and do not cut corners. With the exception of the refills, all kits come with all the equipment required to run the tests including vials, syringes, and titrator if necessary. If you are looking for a really nice kit, then the Pro Kit is the way to go, if you are trying to save money the Marine Care Kits are what you are looking for.
