overflow options

[Xclusive Reef]

I wanted to get people's opinions on the type of overflow box? I am not sure if I want to do something with internal box only or something like a ghost overflow with rear box as well. looking to minimize as much as possible so i get no leaks. thinking if i get the ghost overflow it has more chances of leaks?

I think that the chances of leaking for both of them are about equal. So with that said, definitely the ghost overflow!

I would think more with the ghost since it can leak from the back box where it meets the glass or the bulk heads. in the first design it can only fail at the bulkheads.
