Do I need to reinforce the floor?

[reefwars]

is the floor open from underneathe?? if so build a load bearing wall either permanately or temporarily. fwiw ive had a 180g in the same situation loaded with everything and i had 2x 10 joists and it was fine, not saying its ideal but you would be surprised what your floor holds and my house was 60 yrs old lol id still brace it from underneathe if possible
