Thanks 岩礁園丁 ! As you said, the most critical part is the 同軸90度外曲內分叉. From you post, it seems that you didn't use this part in your tank. Is it because you couldn't find this part in either HK or Macau? If I drill a hole at a normal 90度曲 and stick a small pipe through this hole by using epoxy, do you think it will work out? I never use sump tank. I don't know how large force down flow water causes. I am afriad that it will cause this DIY part falling apart.
