tank remodeling,sump question? (last page)

[eli@fijireefrock.com]

While waiting for another couple days till the 240glns is filled,I am trying to maximize the space into the sump,so here is a question.
Sump size is 100 glns that on the top has glass bracing in the middle that measures 19" by 20" that pretty much covers 1/3 of the 100 glns,how possible is it to remove that and would I run into problems later on?
