Just figured id tell ya, you can buy full hoods for almost any size tank at online mail order places. If you have a center brace like you said you need to buy 2 and they make them wider to fit your 75. Me i just buy 10 dollar piece of plexiglass and make my own. Very simple to do and then all you need to do is buy striplights. You can cut and predrill for the small hinges that u can buy at hardware store for pennies. works extremely well for me. If you need help just pm me.
