Overflow Question

Overflow box advocate here...lol
People who tell you having a drilled tank is better or safer just havent used an overflow box before or did not understand how to properly set them up.

I have a drilled 50 gallon and a 95 gallon with a u-tube DIY overflow and neither has ever flooded or caused a problem.

IME, you don't want a CPR overflow though, the ones that use the aqualifter to start siphon again are nowhere near as fool proof as those that dont require restarting at all...

like this one.
