Stresscoat is no good for saltwater expecially if your going to run a skimmer. The reason is the stress coat will cause the skimmer to go psycotic.
Wait at least 1 day after adding salt for the chemical reactions to complete then check your salinity. The salt bags come in sizes that usually fit most popular tanks so if you added two bags of teh correct size you should be ok. Like if you have a 75 gal
tank and you added a 25 gal
bag and a 50 gal
If you used tap water then you should add a declorinator albeit one that does not enhance the 'slime coat'.
