| I'm a relative novice, but it seems to me that it would be relatively easy to place retro bottom drains in each section and run the piping out the side at the bottom. Of course with a running streamyou would have to put the BD's at end of each section. You wouln't have the circular currents that you get in a pond w/ traditional BD's and TPR's. I would think it would work better than nothing, tho. |
