Kodiak,
You are correct, partially, in your statement. The chloride only protects
against the nitrite poisoning of the blood if the chloride levels are 10 to
1 over the nitrite levels. That is to say, if your nitrite is .2ppm in your
tank your chloride level in the water must be 2ppm. Just putting salt in
your tank is not going to protect your fish unless you maintain this ratio.
This also means that if the nitrite level increases so must the chloride
rate according to the ratio if you want to maintain the protection.
This idea of adding salt is not a magic pill of adding some salt to protect
against nitrite poisoning. It is something that has to monitored all the
time and responded to if the nitrite gets higher.
This techniques is usually practiced by catfish farmers, who usually
maintain a 50 - 100ppm in their acre size ponds.
To answer your other question, no, putting salt in your new tank is not a
good idea as the salt retards the establishment of the biobugs in your tank
making it to take longer to gain a cycled tank. In addition, salt makes it
harder for the water to hold oxygen, depending on the water temperature. It
could reduce your ppm of oxygen by .5ppm. Oxygen is paramount in
establishing a cycled tank. On the average a long cycling for me is
typically about 2 weeks to obtain a fully cycled tank. The other thing you
have to remember that the warmer the water the less oxygen is being held by
the water.
