You can see what's going on much better than I can. If you think the situation warrents the use of Triple sulfa which can be used in conjunction with salt, do a 50% water change and run carbon in the filter for two days. Do and additional 25% water change, add 1 tablespoon of salt per 5 gallons of water and dose with the sulfa as per the instructions on the package. Otherwise if you just want to try the salt do as discribed above without the addition of the sulfa. Treat with the salt for ten days with a 25% WC every other day replacing the salt removed by the water change. You can then start using the sulfa if you feel it's necessary at any time after a water change.

Unplug the heater and get the water temp down to the 72-75 degree range if possible. It will slow down the progression of the bacteria. Remove any carbon if you use it do a 50% water change and start treating with the sulfa ASAP. Move fast or the chances of recovery will be low.
