Oh and I just wanted to make sure you don't feel picked on here St6_Devgru. I have been keeping fish for many years off and on and didn't know anything about cycling my tank until just over 2 years ago
I always used fish and always got frustrated when they would die off and on for the first 6 months or so. Now that I know better I hope to help others to NOT make some of my mistakes.

Blue, that's a much better and more accurate answer. :D Alongside of the water changes, that's also an indication to check for ammonia, nitrate, and pH to see what's "off" and how to best fix it. If NO2 shows up, there's a reason for it, usually either the tank is new and cycling, or the biological load in the tank has been depleted, and the tank is going through a "mini cycle".
Salt won't fix the NO2 problem, only help to soothe the fish from the effects... IF they are fish that can tolerate salt. Table salt is a no no, marine salt is the safest and best thing to use. Standard aquarium salt is full of sodium chloride, which can cause permanent neurological damage to the fish, especially if they're sensitive to it. Marine salt contains the many different kinds of salts that are most needed in an aquarium without the high percentage of sodium chloride.
What kind of symptoms are we dealing with?

None at all. Charles(St6_Devgru) was just asking what NO2 means.:)

I'm ready for the pressure.
The drama and the pleasure!
If there is one thing I want to see here, it's HUMOR.
I believe I can fly!
I believe I can touch the sky!
I think about it every night and day!
I stand in awe of my body.
