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?
No I shouldn’t use it or no there’s no good reason not to? I phrased my question badly...Nope
ThankyouRealised I phrased my answer badly. No reason not to. As you say its just NaCl.
Why not? Its fineI agree - no.
Cool, aquarium salt costs 3-4 times the price. Far too much just to have a picture of a fish on the packet.aquarium salt is normally rock salt so use it.
