I do my water changes with a python. What is the best way to re add the start when changing the water? I don't wanna do it all at once after filling the tank back up, i figured that would be too rough on the fish. And i figured adding all fo it before filling the tank back up would have the same effect.

put the salt in the filter after you add the water. then the salinity slowly re-climbs to where you want it. the change isn't large enough to really create enough stress on the fish to cause any casualties or etc. I do this with my discus with no fatalities or extreme stress...

Goodluck

Hi,
First, you have to know what your salt concentration is
in the main tank. How many tablespoons/gallon or what
portion of a cup to gallon. If it is a brackish water tank
then you should have a hygrometer and know what the
specific gravity is.

Than, you take your cue from the saltwater folks. If you
are draining out X gallons of water, then have X gallons
premixed and simply bring to temperature and add it back
to the tank.

When I had a tank that needed some salt, a teaspoon per x
amount of water,
(I forget now, 40 years later, whether it was per one
or five gallons) after I'd refilled the tank, I simply
sprinkled the required amount of salt from the across
the surface of the water to make up for what I'd
drained, allowing the tank circulation to mix the salt.

As Brandeeno says, its generally too little or slight
a change to make a big difference.

Is this the same tank in Hospital re the Mollies Shimmering.
If so you will have to calculate how much is required how you do that other than guess work I would check with your LFS where you are buying the salt.

When adding it I would add it very slowly its easy to add a little more but lowering the salt content means water changes to get the level correct.
I would take some tank water out add part of the measured/required salt mix it up completely then pour it over a large area.
