Salt Water Marine Aquarium Design & Installation
Also known as salt water aquariums, marine aquariums are often considered to be the ultimate in fishkeeping. Being much more sensitive to changes in water quality than tropical fish, marine fish need very high quality water which usually means more regular maintenance.
They cannot be filled with tap water but require pure water such as reverse osmosis filtered water which then needs to be salted using marine grade salt (widely available) to the correct level. For regular water changes the options are usually to buy pre salted water in or to have a small reverse osmosis system set up near the aquarium.
