Marine fish and reefs are susceptible to mild changes in their environment. Hence, you need to closely monitor the water chemistry, light, and temperature to ensure a stable marine aquarium. On a safer note, it is advised that you understand the basic maintenance tips before setting a saltwater aquarium.
You can select stainless steel, plastic, or metal-coated with plastic equipment rather than pure metal ones. Install other necessary equipment like filter system, sump, powerhead, and heater by following the instructions of the manufacturer.
The water should be filtered and sterilized at the same time. For this purpose, you can consider ozone filtration and protein skimmer. Filtration should be performed in such a way that some useful bacteria and microbes are retained in the water. Protein skimmers clean the organic debris before they get converted into plant nutrients.
Majority of the marine fish are active between 75 to 80 degrees F. Accordingly, you can set the temperature of the heater. Monitor the thermometer level thoroughly for any change in the temperature.
The aquarium should be placed away from the window or any opening from where direct sunlight is received. Sunlight is a major triggering factor for the growth of aquarium algae that are very difficult to control. You can place it near an electric outlet, so as to provide easy access for any external light or temperature fixtures.
Water and Salinity
For preparing the saline water, purchase aquarium salt and mix it with water as per the instructions. A hydrometer is necessary in order to monitor the gravity and/or salinity. As evaporation occurs, the saline concentration can be maintained by adding water to a specific level.
Substrate and Plants
Use one pound of gravel per gallon of water that the aquarium holds. Vacuum clean the gravel before adding in the aquarium. Once the substrate is added, place the decorative live plants by inserting their lower portion on the substrate.
