The siting of a marine aquarium is reasonably essential. If subjected to powerful sunlight, it has a tendency to turn green extremely quick, so find a corner protected from the direct rays of the sun.
The floor of the tank should be covered using the typical aquarium sand-well washed, of course-but regrettably plants can't be introduced. There's no recognized marine vegetation which will prosper in such confinement; as a result the furnishing is restricted to rocks, shells, corals and stones. Keep in mind usually to boil them in water prior to introducing them into the tank.
