Hi all,

I have just purchased a 10’ tank and it includes a central weir which has six holes in the bottom of it.

Any ideas why it has this many? How is it designed to be set up?

Thanks.

Double bean animal.

Or double herbie and two returns.

Or ...

Presumably it has a sump as well.

Hole sizes would also help clear things up.

I'm guessing 2 holes for 1" bulkheads as the drains and 4 holes for 3/4" bulkheads for the returns.
