Hey no problem, that is what we are here for.
I also want to say this about Salt and guppies. Guppies will live in Salt water, i have seen it with my own eyes and in my own tanks. It was before I really knew anything about lion fish but that is another story. I kept a nice Lion Fish when I first started the SW hobby about 20 years ago. I fed him Guppies and sometimes they would get away. Some would survive in the tank for few weeks before becoming a meal. I have also seen this at fish stores as well but the problem with this is yes, they will survive but eventually the salt will cause stress on their organs and they will sooner or later have a shortened life span.
If you treat any ailments with salt, after the treatments is done, do water changes but do not replenish the salt, but do it slowly so not to place your fish into shock.
