welcome to fishlore!!!
im sorry its under these circumstances though

at this point, the tank is very overstocked and probably running wild for parimeters...I see you use test strips, which do not give accurate readings and probably giving you false hope..
API makes a liquid master
test kit which has everything you need, will do 100s of tests, and is super reliable.......the product stability (if you are still using it) is probably keeping the tank from properly cycling...its not a bacteria that is aquatic and will actually eat up the good bacteria needed to cycle a tank......so once you stop using that, the tank will go through a cycle like its suppose too...doing some daily water changes with your prime to keep the fish safe, will be a few weeks once you stop using stability....im not sure about the ram not caring for salt, but MOST fresh water fish dont require it and it acts more of an old school method....it irritates them and causes them to overproduce slime coat...so the stress from using salt, could also be a major issue...rams are super sensitive to different waters and if the test strips are telling you no
ammonia/nitrites and there really is, that will cause all the symptoms you are getting from him which indicate to me, there is ammonia........I hope things look up!
