By standardizing cost based on real additive concentration and evaluating results. Our mission is the right reef additive the first time instead of guessing your way through bottles.

Every additive we test is purchased by Serious Reefs, which ensures every review remains fully unfiltered, data-driven, and focused on what matters: building healthier, more successful reef tank
