No need to remove all the water to get rid of the salt. Your normal, water changes should remove a lot of it fairly quickly if you don't put salt in the water that goes back into the tank.
i really wanted gouramis, but the label said they required salt so i didn't buy it... now i have a cichlid tank ...
stupid false information
LOL...It always is advisable not to take LFS advice seriously. Most of these do not deserve a business in the hobby. It's marketing ploy all over again.
Thanks everyone ofr your help. As of now, I've decided to postpone on buying the gouramis until my water changes take some salt water out to a decent level. I appreciate all your help.
