I wasn't aware of a link btwn salinity and alkalinity. Explains my phantom Alk drop last week. ty
Its not really a link per say but but both being functions of dilution.
Your salt mix roughly contains is made up of several compounds NaCl being the most numerous but the other compounds are roughly proportional(settling can throw this out of whack a little) to the NaCl dilution.
Easier to understand if use metric units
As an example if your salt mix is 8 dkh at 1.026 SG.
Your solution will contain 35 ppt NaCl and .143ppt Ca(HCO3)2 in respect to the water present.
So if mix to only 30ppt or 15% less salty
You will also have 15% less alkalinity.
Hopefully that makes sense [emoji23]
