Table salt vs aquarium salt

[s2matt]

hi

saw those aquarium salt sold in fish shop, even have nice blue colur one.
Is there a difference from the table salt? I am used to adding table
salt to my tank when my fishes are not doing well...

Go to older provision shop - get those "rough salt". Most salted vegetable vendors in the wet market sell them in big packet like 1-2 kg.

Personally, I don't buy from LFS as these salt is overpriced.

Barmby is right. I also used to buy those 3Kg pack salt from provision shops or even NTUC. All salt are the same, they originated from the sea.

Epsom salt is the same thing, usually sold in america in drug stores for less then a buck per pound.

Is there a difference using iodized and non-iodized salt? Also, I saw some "sea salt" sold in NTUC, can i use those for the aquarium?

Use sea salt/rock salt.
IMHO those fancy blue salt is not all that.
Iodized salt is for human consumption to ward off thyroid problems if I'm not mistaken.

Dame is there any truth to this? Cos I paid $2 for a 500g pkt. Same time I went grocery shopping and got a 500g pkt table salt for cooking for $0.60 only!
Are they the same?

[Ripper]

I prefer using coarse than fine salt from supermarket.

Most table salt is mined from the ground actually, sea salt is pricey stuff. Any salt should be fine for buffering water for freshwater fishes, but definitely no blue or pink salt (they are nitrate salt i think), try and avoid those reduced sodium salt. Iodized or non iodized makes no difference imo.
