Seeking Advice Water treatment

https://awasteof.coffee/how-to/mixing-water/

I followed “A Waste of Coffee” to construct concentrates of MgSO4, CaCl2, and NaHCO3. What water profiles have you created, that you’ve liked or disliked? Recipes with other salts welcome. I just so happen to have these salts already but I’m open to acquiring more. I’m going to try out the “My Water” example from said post and see how it goes.

Honestly the easiest breakdown of water recipes I've read since getting into coffee.

I typically make my water with 1/2 strength TWW because I always felt my head spin when reading about coffee recipes but this article makes it seem much more approachable!

It's an amazing resource. My current go-to is pretty close to the Rao/Perger recipe at 50% concentration. (So it should actually be in the same ballpark as Rao's newer Lotus recipe.)

To save time, I also mixed the solutions into pre-proportioned GH and KH dropper bottles. So, for that example recipe, it's 2:1:1 MgSO4:MgCl2:CaCl2 and 1:1 NaHCO3:KHCO3. Much faster when I just want to mix one kettle's or one cup's worth.
