OK folks here goes nothin'.... I built the bog 4' wide by 11' long and 11" deep the water level in the bog is 12" below the water level in the pond. when the stand pipe is placed in its fitting in the bottom of the bog, the water level inside the stand pipe is the same as the water level in the koi pond. lifting the stand pipe up from its fitting causes the water in the pond to rush trough the 3" bottom drain while taking a great deal of muck with it, straight to the bog thus feeding my bog plants. As soon as the mucky, dark water gushing into the bog clears up, I stab the stand pipe back into its seat, or fitting. I have two bottom drains in this pond for the purpose of daily removal of the bottom water and muck, which usually happens to be the most toxic water in the pond. It helps take some of the load off my bio filter...makes it happy....makes fishies happy.....makes ME happy. Though I didn't show it in the diagram, the intake for the pump and filter system is 18" from the bottom, mounted in the side of the pond so that in the off occasion that I have a line break or some other mishap, the pond cannot be drained down and leave my fish without water. I'd much rather burn up a swimming pool pump than loose my fish by pumping the pond dry. I backwash the mechanical filter into this bog on a daily basis also. Bog plants for the most part are aquatic weeds and most people feel that weeds don't need feeding but I feed my weeds!!! I will even put a layer of osmocote 13-13-13 in the bottom of the tub before planting bog plants and lilies in them. So, there is a rough diagram to refer to and I thought I'd throw in a photo showing the other side of the bog just in case you missed it in one of my other posts. Holler if ya have any Q's and I'll try to come up with some A's.
Oh yes , Red Stem Thalia and parrots feather are in the bog photo sorry the thalia is so small, I have images of larger specimens in the yard.
