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.

Organic Carbon Source

#1 KH Complex includes organic alkalinity sources that help reduce nitrate and phosphate, making it ideal for aquariums with higher nutrient levels.

Trace Element Support

Provides essential trace elements, including iodine, iron, selenium, cobalt, molybdenum, vanadium, and more, without the risk of harmful accumulation.

Highly Concentrated

Each 2,700ml bottle delivers 38,500 °dKH of alkalinity and 270,000 mg of calcium, making it one of the most concentrated dosing systems available. Approximately five 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

No mixing required. Simply dose directly from the bottle with a dosing pump or by hand. (Please note, Part #1 may precipitate out of solution. Please make sure it is back in solution before using.)
