can somebody point me in the right direction

I tried searching but couldnt really find what I was looking for. I dont know if it even exists though. Im looking for some sort of calculator or graph for maintaining salinity during water changes. Example if my current SG is 1.026 and I want to do a 10% water change and I want to maintain that 1.026, what SG do I need to make the change water to keep it the same. Make sense? Thanks in advance.

For different sg values, there may be a calculator around, but I do not know it off hand.

It is easy to calculate when necessary. We can show how if you need it.
