TESTING Reef Tank Parameters - Newbie Tank Build

In this episode of our Newbie Tank Build series, Jimmy and Mark discuss why testing your parameters consistently will help your corals thrive. Join us as we share which parameters you should pay attention to when monitoring your reef tank, why you should test at the same time, and how you'll know when to start supplementing your tank.
► PRO TIP: Test alkalinity at the same time everyday.
