personally, I don't recommend a bog with soil as part of your pond. The bog will trap and hold an amazing amount of gunk, bacteria and other nasties. It's not removed these nasties from the water column, rather just traping them for constant exposure. If you ever needed to treat for parasites, many treatments would be rendered ineffective before they ever had a chance to do their job beause of the large amount of organics in your system.
Another note regarding lotus. They MUST be contained in a pot with no holes!!! Lotus are horribly agressive. If you do build a bog and put one lotus tuber in there, it won't be long before the bog is nothing but a huge mass of lotus roots.
