Need ideas on reinforcing floor from the top?

  • We are currently upgrading MFK. thanks! -neo
honestly ive had 210 in the mddle of a room on 2nd floor. youll be fine

/facepalm.

I see people say this all the time and it is stupid. It may work for you but you cannot say it will work for him. There are hundreds of variables that you cannot predict and that could result in the tank going through his floor. How old is his house? What design is the flooring? What materials were used? Is there any wood rot or damage to the flooring? etc.
 
I had a 180gallon on a exterior wall at my parents, there joists are 2x8 hardwood, never had a problem. I put a 6x6 kiddie pool in the middle of the room and it bowed the floor 1/8" when filled. The bathroom door was right next to my bedroom so you could tell when I was doing water changes. Door slammed shut when pool was full, half empty the door touched the carpet :)

Your very lucky. ANY bending is a bad sign. Wood hates to bend and it sounds like that would have eventually been very bad.

My Cabinet tank is complete, do you guys think this will be good at spreading the weight of th etank on the floor?
 
That's a little tough to answer with two photo's and no construction details.
Perhaps instead of piggybacking your questions onto this old thread you should start your own.
Your question is valid.
Your stand looks good.
Start a thread and add a little more detail.
If you have construction photo's that would help alot.
Judging purely from the photo's the framing is pretty light, but, that's ok if your construction techniques are well thought out.
I would be as concerned with how rigid the stand is with how well it transfers that load to the floor.
 
the typical residential floor loads is 40 lbs per square foot . a 2x5 tank and stand covers 10 square feet. or 400 lbs total. a 1/4" steal (not wood) plate twice the size would give you twice the wight of 800 lbs. You could build a platform of wood. but that would have to be at lease 2x4" on edge with 3/4" ply on both the top an botom. It would be helful to know the direction of the joists. You want to span as many as posible.

is that an internal hall out side the door or a pourch
 
Would it help to more evenly distribute the weight if instead of using just a large piece of wood underneath you actually make a platform/stage type stand with it's own supports as well? kind of like putting eggcrate on the bottom of your glass tank to help spread out the weight of rocks...

Do you have a basement? Assuming you do, just put some 4x4 posts under the floor joists where the tank will sit. Just drain you current tank and put the posts in, then fill your new tank. If you don't have a basement you don't have to worry about the weight. But I assume you do have a basement and you said you want to support it from above so adding supports below isn't an option. SO put the tank near a load bearing wall and you should be okay.

I don't understand what you mean by this? What if the tank was on the first floor but there was a crawl space under that? The only time you wouldn't have to worry is if your tank was on the first floor and your house set on a concrete slab.
