Floor - To brace or not to brace??

[Dearth]

The floor will support your tank however because it will be supported by one beam anytime you get a person walking by you will see a swing in the water I know because I went through it before I would personally add cross bracing and/or a post to help distribute the weight a lil more but the choice is yours to make what ever you decide and good luck with it

I have to second gregzz4 on this one. That structure will handle the weight no problem, but your tank will bounce a bit for sure. For $100 of lumber you can sleep better at night.

am I missing something, it's only a 6' span, where's all this bouncing coming from? Planning a party between the tank and those side walls?

My 125 has 1 single 2x10 under it running length wise may not be ideal but I don't get any movement at all I wish my tank had that support guess I could upgrade but it's not going anywhere.

That extra beam will do nothing for stability, the one joist is fine for holding the weight, as others have pointed out it's a short span. If your hardwood was installed correctly (perpendicular to joists) you'd be fine however since for whatever reason it's not there is some potential for a rocking effect over the one joist. Again just to clarify the extra beam you sketched in will do absolutely nothing for this issue. That said there's an easy and simply solution, anchor the stand to the wall. Run a horizontal 2x4, or whatever, and screw to to your studs then screw your stand to that. For best results fill your tank half way and insure it's level before screw the stand to the wall.

Like I said little buddy you'll be fine I've seen worse for sure


Really like Steve's idea of fixing stand to the wall behind the tank that's actually genius

Unless its concrete I think all floors have bounce to them , if your worried about your joist you could stitch another on there and add some cross bracing but I don't see any issues with the way it is right now.

thanks for all the replies guys. I think im going to try and add another joist in between the black ABS and the HVAC so there are two beneath the tank just for piece of mind. i don't doubt that it will hold the weight the way it is now but i do have gatherings over from time to time and id rather not see the tank rocking under any added weight

IMHO, you have the opportunity to over-engineer and over build now, do it , as much as u think u need, then double it (LMAO) and you will rest easy later happy to never worry about it down the road
