A two-component sea salt designed for the most demanding reef aquariums.
FAUNA MARIN - PRS - Purity Reef Salt 11kg is not your typical reef salt. It was developed to meet the needs of experienced aquarists seeking a clean, easy-to-read, and fully controllable synthetic seawater base. Its two-component formula allows for precise water preparation, with a two-step dissolution process. This method isn't meant to complicate things; on the contrary, it offers greater control over the final composition and integrates perfectly into a serious reef maintenance routine.
This product is particularly useful in marine aquariums where every parameter matters. In a tank with a high concentration of hard corals, in an ICP-managed setup, or in a system where supplementation is already finely tuned, it becomes advantageous to start with fresh water that doesn't introduce unnecessary elements. This is precisely what this salt offers: a clean analytical base , designed to prevent unwanted additions and allow the aquarist to create a mineral balance according to the tank's actual needs.
An ultra-pure formula without unnecessary trace elements
One of the major advantages of Purity Reef Salt is its deliberately minimalist formulation. While many salts heavily enrich the water with trace elements, this one takes the opposite approach. It intentionally contains no added non-essential trace elements , thus limiting gradual accumulation and the need for additional dosages. Only iodine and molybdenum are present, in concentrations designed to support a consistent biological base without interfering with a separate supplementation program.
This approach will be of particular interest to aquarists who already use targeted solutions to adjust trace elements. With more conventional salt, it can be difficult to distinguish what actually comes from the salt itself and what from the supplemental dosage. Here, the approach is much cleaner: the water chemistry remains transparent , adjustments are easier to manage, and corrections can be made individually without disrupting the system's natural balance.
An excellent choice for sensitive tanks, ICP analyses, and correction phases
FAUNA MARIN - PRS - Purity Reef Salt 11kg is also perfectly suited to delicate systems. When a reef aquarium is going through a difficult period, with the appearance of algae, cyanobacteria, or dinoflagellates, starting with water prepared with a very high-purity salt can help restore balance. It's not a miracle product, but it's clearly a useful tool for aquarists who want to avoid adding unnecessary compounds during a rebalancing phase.
It is also very useful in tanks where corals react strongly to even the slightest changes or in setups where the water is monitored analytically. In these contexts, the salt's neutrality becomes a real advantage. It allows for more precise work, better interpretation of test results, and adjustments to supplementation on a case-by-case basis. For a precisely managed marine aquarium, this type of salt provides a particularly clean starting point .
Balanced parameters to prepare stable and consistent seawater
Once properly prepared, the resulting water aims for a salinity of approximately 33 to 35 PSU , which corresponds to a range widely used in reef aquariums. The stated composition shows balanced values for the major parameters of seawater: magnesium between 1250 and 1340 mg/l , calcium between 410 and 440 mg/l , potassium between 380 and 400 mg/l , alkalinity around 8.0 to 8.5 dKH , and pH between 8.0 and 8.4 . Consistent levels of sodium, chloride, sulfate, strontium, fluoride, iodine, and molybdenum are also present.
This product will appeal to aquarists who want to prepare technically stable water without imposing an excessive amount of supplements from the outset. It's not an overly concentrated salt, but a formulation designed to provide a controlled base , capable of being integrated into a comprehensive maintenance and judicious supplementation strategy.
Instructions for using Purity Reef Salt 11kg for precise water preparation
The preparation is a two-step process, which is an integral part of the product's concept. First, dissolve 124 g in 10 liters of reverse osmosis water in a clean container, stirring continuously. After approximately 5 minutes , add another 266 g , still stirring vigorously. Typically, the water will be clear and ready to use after about 15 minutes .
For best results, it is recommended to weigh the two components separately, use reverse osmosis water at a temperature between 23 and 26°C , and check the salinity before use. This method ensures excellent consistency between water changes, which is crucial in a sensitive reef aquarium. Some slight clumps may appear in the salt due to its high purity, but these are harmless and dissolve completely with water movement.
Why this Fauna Marin salt is primarily intended for experienced aquarists
Purity Reef Salt 11kg is not designed for general use. It is clearly intended for users who already have a good understanding of seawater chemistry, the needs of corals, and the role of trace elements in a marine aquarium. Its advantage lies precisely in the absence of unnecessary additives: to get the best results, you must be able to analyze the tank's situation and then supplement it accordingly.
In other words, this salt is particularly well-suited to aquarists who rely on reliable testing, regular analysis, and a personalized dosing approach. This is what makes it a unique product on the market. It doesn't try to do everything for the user ; on the contrary, it provides a highly pure base for creating water perfectly suited to their system.
Convenient 11 kg format, easy storage and precautions for use
The 11 kg format is ideal for aquarists who want a comfortable quantity for their water preparations without needing multiple containers. To preserve the product's qualities, it is recommended to store it in a dry place at room temperature, away from light and contamination. As with all synthetic sea salt, it is best to handle the product cleanly, carefully reseal the packaging after use, and avoid any unnecessary exposure to moisture.
For safety, a few simple precautions are necessary: keep out of reach of children, avoid contact with eyes, do not inhale the dust, and wash your hands after handling. This product is intended exclusively for saltwater aquariums . Once empty, the packaging can be disposed of through standard sorting or recycling channels according to local regulations.
