Salt Level Question

not to hijak the topic, but say i've been cheating a little on my mollies and violet goby[dragon fish]. they have been living a freshwater existence. so instead of just whacking them hard into brackish, i should go a quarter cup /10 gallons for a week . then a half for a week or two then a cup after about a month?
on the other hand, fish that live near oceans are used to the salt changing / coming in with the tides?

the soon to be brackish tank is the hospital tank this month anyway. for the dragonfish i have to swap out the gravel for sand.

I don't measure with a spoon, I measure with a hydrometer. I keep my GSP at a specific gravity of 1.014-19. That comes out to about 2 cups of marine salt/10 gallons. Teaspoons?????


so a question then from me on this very old thread...i have a ten gallon with a 3 inch yoyo loach, med. algae eater, cherry barb and danio and I just added two bumble bee goby's two days ago...i want to make sure there is enough salt for the goby's (i think a female and a male) so I bought a (floating) hydrometer and it's showing barely more than 1.000. i add the "regular" amount of 1 tblsp. per 5 gallons prior to the goby's. should I be at 1.014 -19 for the goby's or will that kill the other fish?
 
It is not good practice to mix BW and FW fish. One condition or the other is best. Keep the FW fish without salt, and the BW gobies with marine mix.

What "regular amount"? There is no such thing.
 
The "regular" amount shown on the side of the aquarium salt package for general purposes (1 tablespoon per 5 gallons)
 
I was also listening to my brother in law who has FW experience and currently doing SW regarding adding salt to the tank. However my problem is that the goby's were in fresh water with "a little" per the LSF dude salt in the water ( I should have asked exactly how much) and I only have one tank ATM so I need to make sure that all involved fish continue to live. I could have had a 45 gallon with stand delivered tomorrow but I'm a moron and declined so now I have to solve above problem.
