Thanks for the informative thread, I'll be incorporating your design into my 300+G. build I have under way.

I was wondering what you and others think the advantages and disadvantages of a intank weir compared to behind tank weir?
I think behind tank 'looks' better as you do not take up tank space. I'm more concerned about strength. My build will be about a 8 foot wide tank with close to a coast to coast overflow.
Do you think a rear mounted overflow box would add strength like euro bracing would? With a intank weir you would have the strength of the weir and could still ad eruo bracing if you wanted. So I guess my question is about tank strength; intank or behind tank is there a difference in tank strength? Other comments regarding the good and bad of each would also be appreciated.


Thanks.
