FAQ: What's the difference between Seachem Marine Buffer® and Reef Buffer™?

Marine Buffer® has a pK of 8.3. PK is a number that represents the pH of a buffer. Reef Buffer™ has a heavier carbonate influence than Marine Buffer® giving it a higher pK. Because of this, Reef Buffer™ is more successful at overcoming acids where intense biological activity occurs resulting in heavier acid production like in a typical reef aquarium.
