Liquid Salt

Simple, fast, pure.
The best.

why a liquid salt

Supreme Liquid Salt is a salt for the preparation of sea water in 3 components. Components 1 and 2 are very concentrated and contain all the macro elements that form sea water, component 3 contains the micro and trace elements.
3 components are also very useful if you use the Aquatic Lab analysis service. ​This particular configuration is essential if you detect too high values of some components and you want to make the correction.
Once you've experienced the convenience, speed and purity of Supreme, it's hard to go back.

Easy to use

The liquid salt mixes almost instantaneously, without the need to use powerful pumps and without the dangers of precipitation. It remains stable even when opened and it doesn't fear humidity.
To prepare the water you can use the directions on the package or use our software. In few seconds you will know how much osmotic water to use and how much product to add.


The water prepared with Supreme is immediately ready for use, there is no need to wait for the values to stabilize and it is not aggressive on corals.

Very pure

Supreme is made up only of very pure salts, which could not be used in the formulation of a powdered salt due to their hygroscopicity, typical of very pure pharmaceutical salts. The anhydrous salts used in the powder formulations are less pure and contain, even if very low, a higher concentration of pollutants.

Constant composition

The composition of the powdered salts is conditioned by the shape of the salts themselves. The grains are sometimes too large and too few to be able to disperse evenly in the different packages, even after careful mixing. The result is that the micro elements are not homogeneously distributed and there are differences between batch and batch and between different packages.
The liquid formulation allows to have an unprecedented homogeneity, guaranteeing an unmatched product uniformity between the different packages.

How to prepare water with Supreme Liquid Salt

Use the software to calculate the quantities of osmotic water needed and the quantities of Supreme Liquid Salt Part 1, 2 and 3.
Once a perfect reverse osmosis water has been obtained, measure the liters calculated by the software and pour them into a container, taking into account the subsequent additions of the components for the required volume. It is also possible to weigh the water to measure it quickly (1 kg = 1 liter). To have water that can be used immediately, we recommend bringing the temperature to 23-24 °C. Turn on a movement pump or stir immediately after adding each component.
For better accuracy, weigh the components according to the instructions of the software and pour the 3 parts in sequence.
To check salinity, we recommend the use of a refractometer or better a conductivity meter. Usually these instruments have automatic temperature compensation and are easy to read. The use of a hydrometer is however not recommended since the reading must be corrected based on tables and the temperature of the water.

The indication must be 35 PSU (‰ or ppt) using a refractometer, 53 mS using a conductivity meter or 1023 g/l using a densimeter (taking care in this case to calculate the necessary corrections). Using a specific gravity meter (or relative density - usually the scale alongside the salinity scale inside refractometers), the reading should be at 1.026.
Check which tool you are using.
If the reading is lower than the expected value, proceed in steps as with a normal salt, pouring small equal quantities of part 1 and 2 until the desired salinity is reached. For every liter of part 1 and part 2 poured, add 1 ml of part 3.

Why are regular water changes so important?

With the advent of new technologies, such as ICP analysis systems, many companies have mistakenly spread the notion that regular water changes have become unnecessary.
Not everyone knows, however, that corals often live in environments where they struggle to secure living space. During this fight, many of them secrete stinging substances which are not detected by the used analysis systems. This is because ICP analyzes can only measure atoms and not how they are bound together to form molecules.
These stinging substances are intended to inhibit the growth of nearby corals. A real chemical battle is then generated between corals for supremacy. In the open sea, the enormous exchange of water due to sea currents ensures that these substances do not exceed dangerous levels for the entire ecosystem. In the aquarium, using activated carbon helps to eliminate them but a regular water change is essential to maintain balance.
Another thing that ICP analyzes cannot show us is the biological situation of the tank and its bacterial content. Regular water changes help keep our system in balance in all respects.
