Closed loop safety?

[oliverout]

Hi all, I am currently planning my 300g tank for my new home build in North Carolina, I have been looking into flow, closed loops seem to be good, I was curious though, is there anyway to guarantee it wont leak, also where should I place my inlets and outlets?

I cant help with the specific question, but I can bump the thread to see if we can get you some attention.
