RO? We didnt mention anything about RO!

Regular salt, pickling salt (sodium chloride), helps discus gill function and will reduce fungus and bacteria at high enough concentrations. A typical dose is 1 or 2 tablespoons per ten gallon of tank water disolved in a cup and poured in tank. This treatment usually lasts a week or so. Usually used when new discus are introduced to a tank.

Epsom salt (magnesium sulfate) on the other hand, is a laxitive. It will help constipated, bloated fish pass feces (poop). You use 1 or 2 teaspoons for each 10 gallons of tank water. Disolve the epsom salt in a cup of water and pour into tank. It should work in 2 to 4 hours. You can redose after 4 hours, but if it hasn't worked in 24 hours, it probably won't work at all.
