you add all the salt at once

I don't know about anyone else, but I do. Hope that helps!

I added my salt in two seperate amounts....I have snails though....and didn't want to kill them.....otherwise I would've done all at once.

Disolved in water I add it in over about a one hour period.

[Mighty Prawn]

I usually add it over a 24 hour period, dividing the total amount into an amount to be dosed every 4 hours.

That's the instructions I read many moons ago when I got ich in my tank the second time. The first time I got it, I just dumped it all in, and some of my fish died from it. With their weakened condition it almost "descaled" them, is the best way I can describe it.

I added it all at once and had no ill effects with clown loaches and red-hooked silver dollars that are touchy to medications. Never lost a fish and treatment seems to have worked.

I add all at once as well!

I add salt to taste...... all at once.
