Ooops, sorry. I took the word literally.

The originator did indicate " I also added a bog filter about 5 X 2 X 1.5
feet"


Not using exact meanings shure makes things difficult to understand and
keep track of.

Do you want a "bog", "fen", or "marsh"?

I thought when people talked about a "bog filter," they were usually
referring to an upflow gravel pit? (i.e., not really a "bog").
