91g Tank Weight Considerations Running Parallel to Joists

[Cuso]

Hi all, looking for some advice - I have plans of setting up my Reefer 350 system (91g total volume) in the corner of my office, rather small peanuts in comparison to the monster systems out there but just trying to be overly cautious as I've never had a system of this size (coming from 46g and never any consideration of this). Unfortunately, that perfect spot runs parallel to the joists and some reading got me nervous with weight considerations. There's also a rather heavy, solid desk/hutch that would sit next to it on the same ~14ish foot wall/same joist (the 2nd tank is no longer there). The 46g was running in the same spot for a few years until it got broken down, but this is obviously double the size and probably well over double the weight in sheer volume, equipment and such.

I have some pictures of the supports attached and my proposed tank location, it is in the corner, exterior wall, etc. House itself is only about 16 years old... The tank would sit about dead center on that first truss...are there steps I should take to add further support to allow this placement, should I contact an engineer of sorts to take a look, or am I literally just worrying over nothing?

Any help or suggestions would be appreciated!

I placed a jackpost and a section of 4×4 in my garage under one end of my 180, works perfectly. I would probably place one under the center of a 90. If your really worried you could put one under each end for overkill.

Your desk is not light either. Stand in front of the desk, stand on your toes and then drop to your heels. If the floor bounces or flexes a lot id be concerned. But if it did you would have noticed the flexing walking around the office. If the center of the tank is sitting on the truss I wouldnt even worry about it.

If you want piece of mind and have room, adding a jack post wouldnt hurt anything.

I agree with this. If you're too concerned, do what @Steve Burton did since the joist are in an open area. Easy, cheap, and peace of mind for yourself.

I think I would be more concerned if you didn't have that unfinished wall in your basement near it. As others have stated adding a jack post wouldn't be very hard. And maybe you can position it where it would be in between two shelves so it would not stick out and be in the way

Sounds like the going consensus is to pull the trigger on a jack post as a precautionary measure. I appreciate everybody's input!
