Comprehensive Dosing
Delivers 28 key elements, including calcium, magnesium, alkalinity, and 25 trace elements essential for coral health. This comprehensive approach prevents imbalances and supports long-term reef stability.
Coral Growth and Vibrancy
Promotes robust skeletal growth and intense coloration, optimizing the health of your entire reef ecosystem, including small polyp stony (SPS) and large polyp stony (LPS) corals.
High pH Stabilization
Contains only inorganic alkalinity sources that help maintain a higher, more stable pH, which is especially important for sensitive SPS corals.
Balanced Dosing
Provides boron, calcium, potassium, magnesium, strontium, and other major elements in a 1:1 dosing ratio. Supports customized dosing based on your tank's consumption, helping maintain ionic balance and prevent parameter shifts
Trace Element Support
Delivers essential trace elements such as iodine, iron, lithium, manganese, molybdenum, vanadium, and others, engineered to support coral coloration and growth without unwanted buildup.
Highly Concentrated
Each 2,700ml bottle delivers 27,000 °dKH of alkalinity and 200,000 mg of calcium. Approximately 3.6 times more concentrated than traditional Balling two-part systems.
Simplified Maintenance
Replace complex, multi-bottle dosing routines with a streamlined two-part system. Replenishes consumed elements efficiently, reducing the need for water changes when nutrient levels are stable.
Ready to Use
Pre-mixed and dosing pump–ready. No need to dilute or manually prepare. Just connect and dose.
