Totally agree with Fishy above, build your bog bigger if you can, now that you are moving things around, then you won't have to do it later. And, also agree that IF you can run a pump to force the water through PVC piping to the BOTTOM of the bog (if you are changing it, now is the time to do that, while the pea gravel is out of the bog), then let it seep up through the gravel, to the overflow and back into the pond, that will optimize your filtration and it will work probably 200% better than water simply flowing over the bog area. The whole idea of a bog filter is for the water to filter THROUGH the gravel and roots and plants, not just over the top, although over the top is better than nothing. I learned from Addy and her bog, and when I built my first pond in 2011, I built it with a small bog, maybe 3'x5', then before the year was over, I added to it and made it about 3'x8'. I still have it overrun with plants, as I love plants! So, when I built the second pond, my goldfish pond, I made a 3' wide bog across the whole back side of the pond, so it's 15-17' long! It is my only filtration on the pond, and the water is crystal clear. Addy has a huge bog for her huge pond, and her water never has algae or green water or anything but crystal clear water! She will likely chime in about her thread on her bog. It's actually very easy to put the PVC pipes together and plumb it. At first I thought it was difficult, but now that I have plumbed two, with her help, I know it's very easy! Good luck!
