Jack,

I have a Lifereef overflow on my tank and it works really good. I got it out of the US and it cost me about $200 to $250 or so. (can't remember) I did a lot of research before I bought it and found it regarded the best. (better than CPR anyway)

My tank was up and running at the time and I didn't want to tear it down to drill it, but looking back I sure wish I had before I put in corals etc.

I looked into building one myself, but to get the reliablity of the lifereef, you need the 1 1/8 u tube, and that is the tough part to make.

The other thing is, the lifereef box that sits in the tank is huge! 6"x8"x3"

If your tank is in a place where floods won't be a big deal, then go for the DIY (not saying that it will happen, just it may [img]images/smiles/icon_wink.gif[/img] )

JMO, but I will never use tank that is not drilled in the future, even tho I have been lucky this far...knock on wood... [img]images/smiles/icon_cool.gif[/img]
