How to Treat Ich - With Salt

This is kind of a more organized personal note to myself, but if others need this information, all the better!  This treatment has worked for me before, and is much better than using harsh meds.

Supplies
You need:

1. A heater.
2. Aquarium Thermometer
3. Pure salt.  Sea salt, kosher salt, pickling salt, or aquarium salt will work.  As long as there are NO other ingredients listed than salt.  I personally use Alessi Sea Salt with no problems.  (May be available in your local grocery store)
4. Aerator.  If you have a lot of water agitation going on with your filters, you may not need one, but if you've got a bit of a "quiet" filter, it's good to have one just in case.  Heat depletes the oxygen level in the water, so you need to make sure your goldie won't be gasping for air during the treatment.

Treatment
Very slowly, turn the temperature of the tank up to 82 degrees Fahrenheit (27 deg. Celsius).  Rise the temp 1-2 degree increments per day to avoid shocking your goldfish.

Do a 50% water change.  Get your salt.  Add 1 TEAspoon per gallon. (for 50 gallon owners, that's 1 full cup of salt).

12 hours later, add another dose of 1 teaspoon per gallon.

Another 12 hours later, add yet another dose of 1 teaspoon per gallon.

Every 3 days or so, do a 50% water change to suck up any eggs/parasites that have fallen off.  When you do this and replace the water, add in 1 teaspoon of salt for whatever amount you've taken out.  (so if you do a 50% waterchange for a 10 gallon, add in 5 teaspoons for 5 gallons.)

Keep this up for a MINIMUM of 2-3 weeks.  Even though the spots may disappear within the first week, the ich isn't completely treated. That just means the eggs (which are the white dots) have hatched and they are free-floating.

If your fish has stopped flashing, scraping itself, and the white spots don't return after the 3 week mark, then the ich has been treated.  It's ALWAYS better to err on the side of caution and wait at least a week after proclaiming the death of the ich to stop your treatment.
