non-iodized salt(common salt)

Featured Replies

Both common salt and rock salt are at the supermarket. I use rock salt in my tropical tanks all the time to keep down disease (small amount of it though) and epsom salt or tonic salt for individual disease depending on whats wrong.

I use rock salt at times, but its not recommended because it can contain random impurities. Table salt is fine except it has a small amount of Iodine in it. There is some debate over whether that is bad or not. I use table salt for baths etc but dont use it in tanks/brine shrimp hatcheries.

Tonic Salt is the best bet, and its cheap from your local pet store. Its just normal non-iodised salt.

I think you will find if you look at the back of most supermarket salts it is from lake grassmaire ( spelling ) which means it is sea salt.

Plain salt in supermarkets has and anti caking agent to keep it free flow, I use this salt all the time to hatch B/S and also used it when I bred Nothobranchius ( killis from the plains of Southern Africa ) with NO problems at all.

Rock salt MADE in NZ is still sea salt but does not have the anti caking agent, which means it is just salt nothing else.

So the salt to use is plain table salt (No Iodine) or rock salt.

Which means it's salt, nothing else...Except magnesium, calcium, strontium, iodine, potassium, cyanide, sodium, chlorine, sulphur...

Not really, sorry to argue the point - not that it matters.

Some but not all (and don't ask me which as I don't know)fall out of the brine before the sodium chloride, which is a funny term as it does not fall it rises to the top and is blown off by the wind.

If you go to lake grassmaire the wire fences are covered in a cement like product, this is 1 or more of the chemicals on the list.

And thats why it's no good to use as a salt mix for marine organisms, you even have to add stuff to it if you want to grow brine shrimp to adults..
