I don't see why it would have to be the same. You should always dose you tank size- not your water change.

Plus- when you top off there should be no salt. It all mixes in the end.

Just make sure your salt isn't super high or super low either.

That's just my opinion though

it shouldn't be enough to create a fluctuation though especially not one fo more than a full sg, you fill it back up rather rapidly and if its not pretty darn close to your tank water its the same as taking hte fish from the fish store and dumping him in as soon as you walk in the door.

It's the salinity, how much salt is in the water. I use a refractometer. Others use a hydrometer, the swing arm thing.

i dont konw what the price will be in the group buy, but with discounts and because they come with calibration fluid it may be a better deal to go with one from brs.
