overflow?

[hawk70]

I currently have a 75g tank. Its is a basic tank and has no overflow built into it. Should I have a glass cutter punch a hole or two into the top back corners for overflow? If so, how big should the hole or holes be? Is there any alternative to this? Thanks

I don't know about the drilling part, but you could just buy an external overflow. That is what I did. There are a whole bunch out there. People on this site pointed me towards Lifereef overflows. Just put a www and a .com with lifereef in the middle. HTH.

overflows are definatley much easier IMHO unless you already have a reef ready tank.

I currently run a pair of the LifeReef overflows...they are a quality product. Before I'd drill an existing tank I'd look at the overflows from LifeReef. But my next reef will be ordered with built in overflows.
