LW> A local shop advised me to put a little kitchen salt in my freshwater
 LW> tropical tank, is this recommended???
NEVER use regular kitchen salt.  Regular salt has iodine in it that can kill 
the fish.  What you want to look for is NON-IODIZED salt.  You can still find 
it in the grocery store, usually right next to the iodized table salt.  And, 
yes, you always want to add some of this to a new tank.  Add about a teaspoon 
for each 10 gallons.  And remember that the salt does not evaporate, so you 
don't need to add any when you top off your tank.  Just when you do a water 
change.
