Description
xPremium Complete Marine Salt for Reef and Mixed Systems
Fritz Aquatics RPM is a premium marine salt blend crafted from high‑quality raw materials and developed by researchers and marine scientists. It includes all major, minor, and trace elements found in natural seawater, carefully balanced to support the health and longevity of reef livestock and fish-only residents alike. Each batch is produced in Fritz’s own facility in small runs to safeguard consistent quality and purity, rather than relying on generic blenders.
Key benefits at a glance
- All essential major, minor, and trace elements are included in precise ratios.
- Enhanced buffering helps reach a stable pH shortly after mixing.
- Elevated calcium, magnesium, and potassium levels support skeletal growth and proper water chemistry.
- The mix is nitrate-, phosphate-, and ammonia-free to reduce nutrient spikes in your system.
Cleaner production and consistent composition matter. Fritz uses dedicated salt‑blending equipment for aquatic products to minimize contamination, and the uniform particle size reduces stratification, so you get consistent salinity within each batch.
Quality you can rely on
- Small-batch production in Fritz’s own facility ensures tighter quality control.
- In‑house testing assigns lot numbers and verifies chemical quality and purity before shipment.
- RO/DI water with neutral pH and zero TDS is used in QC checks to mirror reef conditions as closely as possible.
The RPM formula is designed for reef setups as well as fish‑only tanks, offering a balanced baseline that supports a variety of inhabitants. This salt is commonly used by public aquariums, zoos, research institutions, and hobbyists who seek reliable ocean-mimicking water. The typical parameters you can expect include salinity of 35 ppt (1.0264 sg), calcium 400–450 ppm, magnesium 1350–1450 ppm, alkalinity 8.0–9.0 dKH, strontium 9 ppm, and potassium around 400 ppm. Be aware that source water can shift alkalinity, so you may need minor adjustments when blending with local water supplies.
Practical use and outcomes
When you mix RPM, you’re preparing seawater designed to support live rock, corals, and other reef organisms with a complete elemental profile. Real-world users often note easier mixing, predictable pH behavior, and a clear, clean saltwater base after dilution. While RPM can support a healthy starting point for your system, outcomes depend on your setup, livestock, and maintenance routine.
