Canyon. To answer your other questions. I have the discharge from the pump going to the pool and the rearing pond when I fill the pool I close the valve to the pond fill the pool then let the muck settle to the bottom then drain the clear water back to the rearing pond. I have a 4" pipe at the bottom of the pool that goes to the pit. The muck is pretty fluid so it goes to the pit it allows the excess water to go away. The other pipe has holes in it but you need to be in the water with it I put on a mask and fins and work it down into the muck. My muck is about 5' deep so I can remove quite a bit in the area that the hose will reach.
