What did you shock with ? Just wanted to remind you that most shock powders will raise your CYA pretty quickly, and until you get an SWG (guessing that's what you meant by "salt pool" ?) you want CYA level in the 30-50 range.
One of the most important pages in Pool School is the table showing the relationship between CYA level and desired FC levels :

What the table says for your case is basically :
- at 16 CYA shock level is a bit below 10, and since swimming up to shock level is generally considered safe your FC level of 7 should be fine
- at 16 CYA you want to target FC=3 and never let it drop below 2
- at 30 CYA (which is probably where you are now after shocking) you want to target FC=4 and never let it drop below 2
- at 50 CYA (which it could be at already depending on the amount of shock you added) the numbers are "target 6, never let drop below 4"
- etc...
Anyways, in general you're more likely to have problems from FC too low than from FC too high. For now you'll need to keep an eye on your CYA level and switch from pucks/shock to bleach pretty soon to avoid driving your CYA level too high. If you used liquid shock (usually slightly stronger bleach) then Carry On
