Unreliable on fish and aquatic animals

To be honest, most Hanna testers are reliable and consistent. The calcium tester is an exception. Results for perhaps the second most important variable in your reef tank will never be consistent. I've watched every video and tried every pro tip, even using lab water instead of RO/DI. Unfortunately Hanna missed one, I would recommend the Seifert test.
