Do I need a center brace?

[Oilers]

Hello simplydiscus,
I was wondering if I needed the center brace(vertically along the 6' length) for this stand that I'm building. It's a 6' long 22" wide and 32.5" high. There will be a sheet of 3/4" plywood on the top and bottom. All the load is going to be distributed on 2x4's lying on their flat sides along the floor. It's just drawn out by hand and scanned. (Hope it doesn't cause you to go blind)

thanks for looking.

I always add center braces on all tank stands that are 6 feet or longer. It is better safe than sorry to have the extra support.

Worst thing is that you put it in and you didn't need it.

Much better than the alternative of you didn't put it in and you see the stand sway or worse collapse.

Worst thing is that you put it in and you didn't need it.

In the long run if you didn't need it, did it hurt anything? If you didn't put one in and all of your discus and tank went crashing into the floor, wouldn't you feel like kicking yourself even harder? It is always better to be safe than sorry by all means.

I usually add braces on tanks 48" and longer especially if they are higher than 20".

As already mentioned, better safe than sorry.

It doesn't cost that much to put it in! What's another buck or two compared to your discus.

If you are using 2X3's for the top frame then you really should have a center brace. Not only will it support the middle but it will help straighten the normally not so straight 2X3's

Oilers, I really think you should put a center brace. I am no carpenter or expert but I did on all mine and it makes me feel much more at ease .

Here is a picture of them . The single tank is a 125.

I have found that if you add some 2x4 to make an X on the back from one top corner to the oppopite bottom it takes the shake out of the stand. or you cover it in ply wood to take the shake out..

My policy also. Who needs the stress of worrying about it? Just do it!

2x4 yes

2x6 preffered eventually it will bow

double 2x6 or double 2x8 with a piece of plywood sandwiched (glued and bolted) in between, no

creating or adding extra supports in the back of the stand and not in the front will make the side create differences in the height of the stand(by extra bowing in one side) that will add extra stress on the seems possibly leadind to leaks

BTW, why do you need it out of the way? For looks?

You could always do it removable, or make a side door if what you want is to be able to remove a Sump or secondary tank.

Dump a five gallon bucket on the floor, now imagine that mess 50x bigger......You need the brace

The long and short of it is you don't need it but it won't hurt.

There really is more wood in there than you need to support the downward force, but if you really want it stable I would suggest using 3/4 plywood on the back and sides. That will give you the lateral strength that you need if the stand isn't perfectly plumb or level.

Even using single 2x2's with 1/2 inch plywood screwed to them will give a stronger platform than what you can get with your 2x3 construction when you nail it together.

If you want to know what it takes to support a 220g or so tank, go look at a petco and see what marineland or oceanic uses for their stands.Lots of particleboard,hot melt glue and staples.

thanks for the replies everybody. my intention was to put 3/4 plywood on the top anyways. but after about a month, it started bowing, so i had a welder weld a beam for me to place in the middle.
