Un-iodised Salt

[fishfishfish]

i was told by my nearest aquarium (AquaZoo),i was told by the owner who is a good family friend that he uses just regular un-iodised salt for all of his marine ta nk and shark tanks.i was wondering if anyone else has used it or tried it?

Non-iodised salt will just be sodium chloride. It will lack all the other elements and minerals found in marine salt (at least 70 are present in most marine salt mixes). It is not suitable for keping brackish tanks.

Remember that brackish water is where the sea and freshwater mix, so the water will have all the same elements and minerals as sea walter, just in a lower concentration.

I don't know much about marine, but do the fish require having the other elements and minerals present in salt mixes or is it just the corals and inverts? I mean, would you be able to keep a fish-only marine tank using non-iodised salt? fishfishfish, does the guy keep an inverts in his marine tank?

Cheers,

How do you know this? Have you compared teh life expectancy of the fish compared to what this person achieves? Have you dissected the fish to ensure the bodies are developping in the wayt one would expect them to?

The fish need the other elements as well. As an example, experiments show that a fish absorbs the majority of its calclium needs from the water, not from eating. Not adding it to the water (in the form of marine salt) will lead to problems.

A fish can probably survive in non marine salt, but it will certainly not thrive.

A fish-haver would feel ok with table salt, a fish-keeper would use marine salt.
