Sorry again for the long wait but starting from the input to the output the parts are pvc street elbows that go over the edge and the PVC goes into the tank as the input then a hose fitting attaches to the female adapter, there is a hose on that with a hose clamp on it, then the hose (Wich is vynl) then goes into a ball valve (the vynl hose didn't fit into the ball valve at first so I rapped plumbing tape around it until I could barley it side the ball valve, the ball valve is connected to a union, the union is then connected to the 1" uniseal which goes into the bucket. The media for the bucket is 100 percent pollyester filling, lava rock and then 1/2 mesh wire so the bottom uniseal doesn't get clogged.( In that order) from the bottom 1" uniseal goes (in this order) uniseal, ball valve and then hose that goes to the pump. The out put of the pump goes hosing (dont know the id or od) then that goes to a female connecter that then goes to street elbows that go over the edge of the tank the water goes out of that(obviously). I just read this over and it doesn't make sense (sometimes) The bucket filter is the same build as the XL canister filter build The King Of DIY did, and the output and input are by Aquapros.
