So basically when I read about bog filters and veggie filters, they are one
in the same?


For ponders we are talking about the same thing.
A true bog exists without any water running through it and is home to acid
loving plants. So we probably shouldn't use the term 'bog filter'.

Veggie filter is running water through the plant's roots and planting media.
The plants take up the nutrients and the media is a place for benefical
bacteria to hang out.
It can be as simple as floating water hyacinths in a stock tank filter, which
is what I do.
