You must do a water change @ least once every two weeks or they will die, I do know some people that can go a month but it's not smart.

What do you mean softener salt is the same as the salt at the lfs? I assume you don't mean IO etc.? what's the % NaCl in IO anyway - I don't recall the composition of seawater of the top of my head. Unfortunately I think hammering in NaCl to 'raise pH and hardness' is an american habit, and pretty useless if not actively harmful

I assume the salt from the LFS is evaporated sea salt. I assumed that water softener salt was the same.
Here in north america we usually add salt as a prophylactic - or as a general treatment for diseases most commonly ich.
some use it at a lower dose after each waterchange to maintain a salt level in the water. as far as I know salt wont change PH.
I dont know what IO means.

My assumptions (in turn) are that marine salts are evaporated sea salts but that water softener salt is purified, whether from land or sea sources. If, like me, you're after the trace elements rather than the NaCl, then the water softener salt would not do the job.

I believe Wayne at home means Instant Ocean by IO.

I never thought of that...
anyway I saw something interesting down in Guelph yesterday. They had evaporated salts from Lake Tanganykia. What they do at the lake is take a cut in half co-conut, and line the inside with leaves. then they add a bit of water each day and it evaporates, they add more, etc, after about 6 months they are left with a big chunk of hard salt. they had 2 of these on sale. this wouldn't work as effectively for Lake Malawi because that lake does not have as much dissolved minerals in it. (I have no reference for this, I recall reading this in a book somewhere)
