ok so once again i am asking for help. I have a 374g display and the crappy part of it is that i have 2 side overflows. they are both on the sides of the tank not the corners. the trapazoid shape totally eats up like 10 inch's on each side of the 10 foot tank. can i blow them out with out messing up the tank, also can this be done with it full of water? is it worth the headache to get more space in the tank. thanks again and if you have pic to post of how you did it that would rock
