Seachem Reef Builder 300g

Product Overview

Seachem Reef Builder 300g raises carbonate alkalinity without immediately impacting pH. With long term use, it tends to stabilise pH at 8.3. Carbonates and calcium are essential for coral growth, and deficiencies can result in reduced growth and declining coral health. Reef Builder helps maintain proper alkalinity while compensating for mineral loss.
