Can I use rock salt instead of aquarium salt?

[Irksome]

It appears that aquarium salt is just NaCl without iodine and anti caking agents. I already have loads of coarse rock salt that has no additives in. Is there any good reason why I need aquarium salt instead?

 

[seangee]

Nope

 

[Irksome]

Nope

No I shouldn’t use it or no there’s no good reason not to? I phrased my question badly...

Realised I phrased my answer badly . No reason not to. As you say its just NaCl.

Cool, aquarium salt costs 3-4 times the price. Far too much just to have a picture of a fish on the packet.

The only thing I've seen mentioned is to make sure you adjust the dose to account for the larger rocks. One teaspoon of aquarium salt measures a different amount when dissolved than a teaspoon of larger pieces of rock salt, ya know? Just something to be aware of when measuring out your doses.
