I use Tee join and an aerator tongue to give aeration and cutting siphon without problem. Photo below is the items require for making it.
From left: 25mm/1" PVC pipe with holes drilled in it, the length is up to you. 15mm PVC pipe about 4 inches cut diagonally with holed end cap on the end. 20~25mm adapter to hold the 15mm PVC pipe, you can use other means to hold the 15mm pipe. and a 25mm Tee.
Photo above the 15mm PVC jammed into the adapter. Below the attachment installed to siphon outlet.
As below siphon activated bubbles and cut off with little problem.
Below is the video of this attachment and how its made.
So far its good I am monitoring it closely for this next few days.
Attach is diagram of the siphon outlet.
With this last bit, I guess my siphon is complete from top to bottom.
