there are probably hundreds of thousands of tanks drilled using sumps over the years. its just a matter of proper planning, setup and plumbing that keeps them from breaking and flooding. whatever the risks are i would much rather have the benefit of my sump rather than hanging crap all over the inside and outside of my tank. when you get into bigger sized setups it's pretty much unavoidable that you are going to need a sump for all the larger equipment.
