The Seachem Reef Builder 300g is a premium solution designed to elevate carbonate alkalinity in marine aquariums without immediately affecting pH levels. This advanced formulation helps maintain a stable pH of 8.3 over time, ensuring optimal conditions for coral growth. Carbonates and calcium are critical for coral health, and any deficiency can halt growth and lead to a rapid decline in coral vitality. Reef Builder effectively supports these vital elements without depleting calcium, magnesium, or strontium, which commonly precipitate with increased alkalinity. It works synergistically with Reef Buffer to achieve balanced carbonate alkalinity and pH enhancements.

Reef Builder stands out by including calcium, magnesium, and strontium, compensating for inevitable losses during alkalinity elevation and efficiently replenishing magnesium routinely depleted in closed systems.

Key Features:

• Raises carbonate alkalinity without affecting pH immediately.
• Supports stable pH at 8.3 for optimal coral health.
• Preserves essential elements like calcium, magnesium, and strontium.
• Facilitates co-use with Reef Buffer for balanced water chemistry.
• Includes sufficient magnesium to restore routine depletion effectively.

For marine aquarium enthusiasts, Seachem Reef Builder offers an efficient and reliable means of maintaining essential water parameters critical for thriving coral environments. By bolstering carbonate alkalinity and preserving vital minerals, it ensures a balanced ecosystem where coral can flourish.
