Anyone using a DIY pipe overflow?

[daniella3d]

I don't understand this design. Do you have an exemple in pics?

So I guess the only disaster scenario is if air gets inside and it lose syphon? then it wont work and the water coming from the sump is going to overflow the tank. I guess putting the pump high enough so not as much water can be sucked if it overflow is a good practice

Looks great anyway. on a 15 gallons nano I don't want to drill or put anything in the tank beside the pump and that overflow pipe. It really look good with only these.
