Hi All
First post here after reading and reading and............... well, you get the point.

I have 2 30g sw tanks currently, and today I will pick up a 120g for my next project (72x21x18). This is a 3/4" glass tank, and isn't drilled. The tank will be build-in so nothing to see at the back.

My question, do I really need to get the tank drilled for a sump? I'd prefer not, but what are your suggestions please?

This will be a FOWLR and sand substrate. My 2 30 g's are reef tanks.

You can always just use a hang on overflow if you are going to have a sump.

That's right...don't hesitate to use the hang-on overflows...but, I recommend that you get the kind with the U-tube. They look like this:

and the overall setup looks like this...

you'd have a water-pump in the sump to return the water to the main tank.

I've had two of them on my reef for over three years and they are very reliable.

[welcome]

and i agree if you do use a overflow get the U tube type much more reliable IMO

Thank you very much for the feedback. I will investigate / read up on the different overflows and go that way.
