Adding Salt to a Freshwater Aquarium

(Last post of the year!  Happy New Year!!!! I hope 2009 brings health, happiness, and security (in many forms) to everyone.)

The other day I was researching how much salt to add to our main freshwater aquarium containing an adult Black Ghost Knife fish (1/2 teaspoon/gallon or a little less for an adult) and remembered a common mistake people new to the hobby tend to make. (Yay! Something to post!)

Common Mistakes (in no order):

• Using the wrong salt
• Adding salt to the tank the wrong way (directly to a filter or dumping in directly all at once)
• Adding too much salt after a water change
