220 gallon tank: Reinforcing Floors

[kingalee]

Looking for some input, I have moved into a new home (an older 1 story home with a crawl space) and was wondering what kind of support I would need for a 220 gallon tank (older tank with stand and hood) if it’s needed. The pictures attached are of the flooring underneath in the crawl space. I’ve had three 55 gallons on the same rack in the middle of the house with no issues but didn’t know if I’d be pushing it with a 220. (If it’s needed how would I do this without adding a bunch of stuff to the house as I’m renting it).

May not need to but Wouldn’t want to do major damage. Maybe a couple long 2x6 to run underneath those joist boards, and attached to foundation or load bearing wall. Set tank perpendicular to the joists, close to wall or in corner for safest results

I'm gonna be puttiing a 155g in my living room in about 6 months. Prior to this I'm actually having someone come in and reinforce my flooring (I have a crawlspace as well). I read a VERY long article on what to expect and how to ensure safety with tanks above a basement or a crawlspace. It was COMPLICATED! There was so much to consider that my takeaway was I am not a structural engineer and need the expert advice one would offer. It'll cost some money, but hey! This is NOT a cheap hobby LOL!!!!

I would build two small 2x4 stud walls. Install walls perpendicular to joists right under tank with 4' spacing between them and add two sets of cross braces at each end. the whole thing should take an hour.

Like that idea
