glass baffle

[asherah]

I need get this glass section out of my sump that's trying to be a baffle lol
It is like only 5 inches tall or something has a peice of eggcrate an sponge in it.
I want to take it out and make another acrylic baffle like i'm planning on putting on the other end.
But I don'tknow how to get the glass part out of there without breaking the sump walls.
I want to take it out to make room for a skimmer.
