DH and I have been debating bottom drains, skimmers, pumps, and filters all weekend. This is our current plan. Thoughts?
1. 2' deep side of the pond with 4" bottom drain, may add aereator
2. 3' deep side of the pond with 4" bottom drain, also may add aereator
3. DIY Settling chamber/vortex
4. Sequence 4200 gph external pump
5. Waterfall weir
6. Sequence 4200 gph external pump
7. Under gravel pipes in bog
If the bottom drains don't cut it, we can always add a surface skimmer or two.
The surface of the bog will look like the one pictured in Helen Nash's Living Pond book (p. 70) and I hope to have a low rise waterfall similar to the one pictured in the Complete Pond Builder (p. 109).
