> Make sure your temp is at around 78 degrees.
> Use the hydrometer to test the specific gravity. This tells you how saline your water is. Aim for 1.023. Instead of dumping the salt into the aquarium directly, use a spare bucket and mix the salt in pure water.
You need to circulate the water you're mixing and aim for temperature a bit higher than that of your tank. So, you will need a heater and powerhead for this. Use your hydrometer to test the salinity once the temperature is at around 79~80. Aim for higher specific gravity if you have lower amount in your tank and vice versa.
You shouldn't be using tap water for the aquarium. So, you'll have to look into buying filtered RO (Reverse Osmosis) water. If you don't have a RO filter unit, look into buying water from your local fish store (LFS) or superstore.
