Alk water change calculations

Acro maniac · Jul 18, 2018

@Randy Holmes-Farley I know, I have seen you make reference to a calculation of the change in level, based on water volume, current alk level and the level and volume of the newly introduced water.
I have searched without sucess. Can you refer me the link ?
Thanks

Do you also know the equation for what elements make up specific gravity or salinity?
Looking at triton results and wondering how to figure out if my refractor is accurate..
Thanks again
