Ok, that definitely didn't age well.

"I have a low-end computer, would Redox work on it?
A CPU is the most complex machine of the world: even the oldest processors are powerful for some tasks but not for others.

The main problem with old computers is the amount of RAM available (they were sold in a era where RAM chips were expensive) and the lack of SSE/AVX extensions (programs use them to speed up the algorithms). Because of this some modern programs may not work or require a lot of RAM to perform complex tasks."

💧 In my geochemical research, I often go beyond pure PHREEQC and use the RedModRphree package in R.
It’s a powerful bridge between thermodynamic modeling and data analysis — allowing Pourbaix (Eh–pH) diagrams to be computed for complex, multicomponent systems with a focus on a specific element.

Here are examples of modeled speciation diagrams for vanadium, lead, and zinc, based on the same high mineralized water sample composition.
They clearly illustrate how each element behaves under changing redox and pH conditions — from soluble oxyanions to sparingly soluble solid phases.
