Question for Seachem Reef salt or AV Salinity users

So, I'm sure we have all heard that the borate levels are higher than usual in these salts and that can mess with alkalinity testing. However almost everything I read about that is pretty old, and there was a statement in 2015 from Seachem about how they have lowered it from about 20x NSW to 4x.

What is a fresh batch typically testing at for alk? If you get a reading of say, 9 dKH I guess you can safely assume the total alk (meq/L) is slightly more?

Thanks

I have been using AV Salinity for a year and half now and I am anywhere from 8-9 with Alk once I test a fresh batch. A average would be more around 8.6-8.8.

Last time I tested Seachem Reef Salt at 35 ppm alkalinity was 145 approximately (it was in the 140s, just don't remember the exact number)

Ok, so the carbonate alk (dKH) is about 8-8.5 which probably makes the overall alkalinity (meq/L) about 9-9.5, roughly. That works for me.
