How do I make saltwater?

Answer 1

Besides the sea salt (such as Reef Crystals or Instant Ocean to name just two brands), you will also need a Hydrometer or Refractometer (Refractometer is more expensive normally but also more accurate and easier to read) to measure the salinity or specific gravity. Most saltwater tanks will have a specific gravity of around 1.021 - 1.025.

Go to a pet store and by the sea salt NOT the aquarium salt. The sea stuff has extra nutrients that marine fish need. Then, put the salt in the water according to the directions on the box.
