If you are in hammonton, any petco will have salt. As most in south Jersey carry salt water live stock. The one in turnersville has salt. Also when you get your hands on salt don't go and abruptly adding it. You will shock the system. The best way to deal with this is to take exactly one gallon of your current water. And an empty measuring container. Grab a table spoon. Put one table spoon of salt into the water and one table spoon of salt into the empty measuring container. Repeat till the water you took out of the tank is at or near your desired salinity. Once you get there, the measuring container should have the appropriate amount of salt per gallon to add to your tank. You take the amount of salt in the measuring container and multiply it by your system size. Then over 48 hours add that salt to your system as far as the fish, if you have a quarantine tank or a large plastic tub you can prep some salt water and add a heater with an air pump to hold them there while your tank gets to where it needs to be. On a side note be careful because your tank might cycle after correcting the salinity. Keep the lights on 100% during the 48 hours to help get the biochemical reactions going. Good luck. I hope this helps anyone that feels thus needs some corrections correct me if I'm wrong.
