The Reef Buffer from Seachem is a highly effective water treatment for aquariums, specifically designed to increase carbonate hardness (KH) without affecting the pH level. This product is ideal for marine aquariums and ensures that the pH remains stable while alkalinity is increased. Reef Buffer is particularly beneficial as it does not consume essential minerals such as calcium, magnesium, or strontium, which are crucial for the health of aquarium inhabitants when used correctly. With a treatment capacity of up to 72,576 liters, Reef Buffer provides a long-lasting solution for water care. Using it in combination with Reef Builder allows for targeted adjustments of water parameters to create optimal conditions for corals and other marine life.
