Description
A high-purity alkalinity supplement designed to stabilize reef systems and support coral growth. Fritz RPM Part 1 delivers balanced carbonate buffering without unwanted metals—ideal for daily dosing or quick adjustments in both beginner and advanced reef aquariums.

A thriving reef demands stability—and that starts with balanced calcium and alkalinity. Fritz RPM Part 1 is a high-purity alkalinity buffer designed to work in harmony with Part 2 (Calcium) to maintain proper ionic ratios and fuel healthy coral growth without introducing unwanted metals or contaminants.


Formulated with pharmaceutical-grade sodium carbonate and bicarbonate, this solution delivers clean, consistent results and dissolves easily in high-flow areas like sumps or return chambers. Use it as part of your daily dosing schedule or for quick adjustments—ideal for systems with moderate to high calcification rates.

  • Supports coral skeleton formation and overall reef stability

  • Completely reef-safe—no harmful metals or contaminants

  • Pairs perfectly with Fritz RPM Part 2 (Calcium)

  • Safe for all reef inhabitants including inverts
