Seachem Reef Builder is specifically formulated to raise carbonate alkalinity in marine aquariums without an immediate impact on pH levels. Continuous use helps stabilise pH at an optimal level of 8.3, promoting healthy conditions for coral growth. Essential for maintaining a balance between carbonates and calcium, Reef Builder prevents the cessation of coral growth and potential decline in coral health.

Suitable for integration with Reef Buffer to achieve comprehensive alkalinity and pH control.
