how do you make a bog filter?
@TERESA Hello and welcome! There are many ways to make a bog filter — this is a broad question. We have several threads on here with excellent information, and a Google search will point you in the right direction. Also, if you have specific questions, we are hear to answer them for you.
Also, you might get better answers if you started your own, separate thread. In most cases, when a question is piggy-backed onto another thread, you are less likely to get the kind of answers you are looking for.
Curious, since this is your 1st post since you joined in 2008, do you know what a “bog filter” is? Do you have a pond? Why not go over to our “introductions“ topic and tell us a little bit about yourself.
