My wife and I have a 55g aquarium housing three black mollies, three clown loaches, a spotted (leopard?) catfish, and a swordtail. We used to keep a little Aquarium Salt in the tank to help our fish breathe, but we ran out some months ago and I would guess the concentration has fallen considerably since then. Our new mollies are sticking to the top of the aquarium (suggesting they are having trouble breathing), so I went to purchase more salt to help them out.
Anyway to make a long story short my wife is upset that I bought plain rock salt instead of the special "aquarium salt". Is there any difference between these two?
Also, what amount of salt would you recommend for my tank? I know the loaches are not very tolerant of salt, but ours had previously shown no signs of stress with a small amount, so it would be helpful to strike a balance between the loaches and the mollies' needs.
