@addy1 and @Meyer Jordan Regarding the depth for a bog..... You know, I've read 12" forever so that's what I've gone by, but when you think about it, your distribution tubing [manifold] is going to be at the bottom of the bog, moving water upwards. That means that the bottom isn't really a void, though there might be channeling that could contribute to some anaerobic activity. When I made my "turtle bog," I went with 12" depth. My bog is set up where the plants and deeper gravel are around the perimeter, leaving a several inch deep pool in the center for the turtles. While the water is clear, if I disturb the gravel, there is a lot of sediment at all levels and that sediment will immediately travel out and into the pond (but only when disturbed -- again, the water itself is clear). Have never noticed an odor, which is good. We're planning now for our "real" bog filter so I'm going to rethink that 12" depth.
