Normally is DIY overflow pipes by custom made tanks with holes then fit with PVC piping or etc...

But if tanks are already done, you can try look for (Tunze) Overflow Box.. I dont know how to box actually works but the theory is the same... If any expert can advise, please guide skybird on the setting up..
