Fritz - Reef Pro Mix (RPM) Salt - Blue Box
Overview
Fritz ProAquatics Reef Pro Mix (RPM) is a high-purity marine salt developed for professional reef and fish-only systems. Carefully formulated in-house using pharmaceutical-grade raw materials, RPM delivers balanced major & minor elements in precise ratios for coral health, long-term stability, and consistent performance.
Unlike generic outsourced blends, Fritz manufactures RPM in small batches at their own facility—ensuring quality control, eliminating contamination risk, and maintaining uniform particle size to reduce settling and improve mix consistency.
