Instar, good input, as I was not aware that flow could be too high in a bog.
[quote=KDO]bog/wetlands/marsh is most efficient with a low flow rate which allows for a longer RT (Resident Time) of the water. 6500 gph is to much flow for a small bog/wetlands/marsh. I would recommend plumbing the bog/wetlands/marsh separate from any waterfall feature. You will still need an aerator
Does this imply that we'll need 2 pumps, one to pump from the bog to the pond and one to pump from the pond to the waterfall? Or could it be just one pump with 2 inputs and some sort of trimmer valve to pull some from each w/output routed to the waterfall...? Not sure how the hydraulics would work on this...
