First filter chamber should filled with brushes. Fill second chamber with green matting (synthetic matting).
The purpose of using brushes in the first chamber is to trap as much solid waste as possible so that those waste will not get into second chamber. The first chamber will act as mechanical filter and the second one will act as bio filter.
The first chamber can be cleaned as often as you wish but do not clean second chamber unless it is really necessary due to problem such as clog. Any cleaning on second chamber will disturb the bacteria and will reduce the efficiency of the bio filter substantially.
When your filter is efficient, the overall system should be odourless. As long as there are sufficient aerobic bacteria available to treat your water, it will be fine.
When there is odour, it mean that anaerobic bacteria has come into play and these sulphur producing bacteria is causing the odour you mentioned.
In normal circumstances, keep a salt concentration of 0.1% in your pond. In time of trouble, increase it to 0.3%.
