Bog building, also called upflow filter, eco filter, wetland filter

[Run91]

YES the idea is to give the water larger path ways to get distributed across the bog before it meets the tighter pack of the smaller stone the key is to make sure you use river rock and that is rock that is rounded and allows for spaces between the rocks if you use chip rock that is jagged this rock will lock together preventing the water from going anywhere and will clog in short time.

Thanks so much. That helps. Now I can start putting the stone in.
