Yes, sera Gravel Gray is perfectly suited for marine aquariums. Its neutral composition guarantees that it will not modify the specific parameters of marine water, such as salinity or pH. It can be used alone or in addition to other types of substrates.
Maintaining sera Gravel Gray is simple. During regular water changes, use a siphon to vacuum up debris that has accumulated on the surface of the gravel. Avoid stirring the gravel too deeply so as not to release buried debris. Regular cleaning will help maintain a clean and healthy environment for your fish and plants.
The amount of sera Gravel Gray needed depends on the size of your aquarium and the desired substrate thickness. In general, a layer of 5 to 7 cm is recommended to promote plant rooting. For a standard aquarium, you can calculate the amount needed by multiplying the length and width of your aquarium (in cm) by the desired thickness (in cm), then dividing the result by 1000 to obtain the volume in liters. Feel free to adjust the quantity according to your specific needs.
