Hi, I am going to upgrade to 300 DD. I need an engineer to come over and provide details to upgrade my floor support since the tank will be going on the first floor, the basement will be the filter room. Thanks.

+realistically if you can see the floor joyces, double them up and maybe add a couple support beams
I think all an engineer is going to tell is exactly what these two gentleman said. ....personally i would do both. Double up joists. Span all the joists and create a structural wall. If you plan it properly, and depending where it falls in your basement (and if its finished or unfinished) the structure can be used to hold equipment, make bookcases, just about anything.
Post some pics of the area, let's take a look.
Old house might be better then new house. They built structures to last.
Good luck!
