Reef powdered salt
Marine Habitat is a dry powdered salt, it does not fear humidity and is the basis of every reef.
It contains all the main and trace elements of tropical sea water and is free from pollutants, NO3 and PO4. It also has a good buffer capacity in order to prevent changes in pH.
Marine Habitat is a salt without excesses, it follows the analysis of natural sea water and imitates it.
Corals don't need increased values of certain elements to grow faster, they need a well-balanced formula.
Marine Habitat dissolves quickly without leaving any residue. Needs a short rest period before use.
How to prepare water with Marine Habitat
Once you have a perfect reverse osmosis water, you need to bring it to the correct temperature. When it reaches 24 °C, turn on the movement pumps at maximum power and begin to salt the water by adding small amounts of Marine Habitat salt, making it dissolve completely before adding more.
Absolutely not to do is throw all the salt at once or add water to the salt, even worse if with little water movement. This promotes the precipitation of calcium and carbonates, leading to a serious imbalance of chemical parameters. When precipitation occurs, in the most severe cases, a whitish mist is observed in the water that is deposited on the glass and on the pumps.
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.
Stop adding salt when the indication of 35 PSU (‰ or ppt) is reached using a refractometer, 53 mS using a conductivity meter or 1023 g/l using a hydrometer (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.
An absolutely not recommended practice is to prepare the water by weighing only the salt, without taking measurements on the obtained salinity.
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 analysis systems used. This is because ICP analysis 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 analysis can't 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.
