Hi there,
often fish will go to the top for extra oxygen when there is an
ammonia spike in the tank. Salt wont do anything for nitrItes or ammonia.
I suggest that you purchase test kits for ammonia, nitrItes and nitrAtes,
to help monitor the situation.
Have your ph tested too....and add some peat moss to the filter,
this will lower the ph, and make the water more acidic, which will
in turn reduce the harmful effects of ammonia and nitrItes.
Do you use Prime water conditioner? If so, drop in a full dose of it,
for the gallons of the tank, and it will detoxify ammonia and nitrItes.
Also, consider adding an air stone, that could help as well.
How often do you do water changes?
I highly recommend at least 35% once weekly, vaccuuming 50%
of the gravel each time, alternating sides.
Also, did you change the filter cartridge at the same time as the water change? This can cause a loss of biological bacteria, and can cause an ammonia spike and a mini cycle.
Always stagger water changes and media changes....always one week between each.
