RPM Part 1, 2, 3 - Fritz Aquatics

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.

Key Features:

• Delivers high-purity carbonate alkalinity

• 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

• Compatible with all dosing systems
