Does anyone know what the effect on the pH is, of the bentonite-lined pond water?
Does that change significantly, over time?
Have folks added pH modifiers for any particular reason?
Why?
What compounds were used?
I can't recall where I saw it, but there was a pond stabilising suggestion that I thought made a lot of sense. It was to travel to a similar, long-established, land-locked pond/lake, to get some inoculum. By carefully filling a few suitable containers, from close to the water's edge, it was suggested that adding that to a new pond would inoculate it with appropriate flora and fauna that would help it achieve balance and stability.
That's another task on the ToDo list, but if the pH is too radically different, such an idea may not work.
