does ne 1 use these without and overflow box? im putting 3 in a 360gal tank and wanted to know if i needed to build the overflow boxes or not thanks

I owuld build an overflow box to protect it. I always imagine the worst and I can see a rock slide breaking the durso off near the bottom and draining the tank. An overflow box will protect it.
