Multifunctional Artificial Reefs (MARs) are alternatives created for the preservation of marine coastal areas. They can be made from various types of materials, and if they are inserted in a suitable environment and under the right conditions, can be colonized by plants and animals as a natural structure. Many aquaculture programs still use rocks removed from natural environments, because little is known about the influence of materials used on artificial reefs in water quality.
In this work, 10 different formulations were developed using cement, coral sand, salt, crushed oyster shell, perlite and water, after dry, the rocks are placed in tanks with 15 liter of salt water and distilled water.
In order to identify the most suitable formulation for later use in aquariums or artificial reefs, after maturation time, the water parameters where evaluate: salinity, density, pH and water hardness.
The water parameters are monitored a week, during 8 weeks.
With the results obtained, we can conclude that the maturation process was not complete, as evidenced by the too alkaline pH. However, the rocks placed in salt water already have a pH very close to that desired in some formulations, which may mean that these are close to reach the end of maturation. The same is not true of rocks in distilled water.
At the end of the 8 weeks of maturation, the rocks were not fully matured. There were differences between the two types of maturation in all analysed parameters
