Health & WellbeingIf I make water for salt water fish, about how much sea salt I need to put in water? And does the sea salt must be cleared
If your are using a product such as Instant Ocean ( www.instantocean.com ) or Reef Crystals ( http://www.instantocean.com/Products/Sea-Salt-Mixes/reef-crystals-sea-salt.aspx ), then directions will be on the container. Other products may also include instructions. The amount of sea salt will depend on the specific gravity you desire. Ocean water, or water used in marine tanks, has a specific gravity of 1.025, so you will need to dissolve enough salt into a quantity of water to reach that level. You will need to allow for 24 hours to make sure the salt has completely dissolved.
