anyone think a 6 inch overhang will be a problem?

[ReeferMan]

Ok so i am trying to setup a frag tank (20l) over top a ref (20l) that hooked up to my sump. Where i want to put it i only have about 30 inches on the floor because of a vent shaft so i was wondering if a 6 inch overhang (36" long tank- 30" stand=6inch overhang) would be ok? Do you think if i make the stand 30 inches on the bottom and a 36 inch area for the tank to rest on would make any difference?

dude, 20L tanks are only 30"

[ReeferMan]

My bad its 30" but i only have 24" on floor space

gotcha. well.

 

your overhang would be 12x6x12 which is 3.7 gallons x 8.5 lbs per gallon = 31.45 lbs of water not supported...

 

i don't know man. 20L aren't super strong. can you just do a 24" tank instead? i think that would work better.

 

are you going to be drilling it? that's a factor as well. if it is drilled, i'd say no. if it's not drilled... maybe. drilling will just increase the stress on the drilled pane, by not having the end supported, and you'd likely get some bowing, and eventually, failure.

THING IS I HAVE TWO SPARE 20L TANKS. They are both drilled in the upper corners. They would be sort of supported and i need to take into consideration its more like 60lbs since there is two tanks.

I wouldn't do it. Tanks are cheap. Just buy a 24" tank.

[ReeferMan]

i like the length though, oh well i have a 24 inch tank as well.

i like the length too, but you're not going to like it when you have 40g of water on the floor, and your main tank (i'm assuming you would run them inline) draining into the broken tank as well

NOPE

Anything is possible if designed correctly.....

Hey chris, I gots an idea . Why not make a full length shelf for under the tank out of say pine and on the very end put screw eyes on the corners (reinforce the corners) then just put two anchor point in your ceiling and run wires to suspend the shelf... like a suspension bridge... We have bookshelves in out RV supported by olny wires and they'll hold a pretty big TV along with a ton of books.

[ReeferMan]

thats a nice pic! Jason i think 360lbs is too much weight for that idea. Dandy any ideas????

[dandy7200]

I can draw it and fax it to you if you like.

Maybe I am misunderstanding, but you weren't planning on just letting 6" of the tank hang off the end of the stand right? You were going to build a stand with a 24" wide base and a 30" wide top. As long as you use something like 2x4s for the top of the stand to provide horizontal support for the full length of the tank, I don't see a problem as far as the tank breaking. My conern would be more of it tipping because it was assymetrical (not on its own but if you bumped it or leaned on it or something). I was going to suggest anchoring it to the wall but Jason's idea is probably better.

 

If this is in a room with exposed joists above, you could even run 2 x4s instead of wire from the front of the stand to the exposed to the joists This would give the overhang area some extra verticle support while at the same time providing some stability. Wouldn't be pretty, but I think it would work. I will, of course, defer to the DIY master . . . What say you Dandy? (whoops, didn't see above post before I sent this)

Dont have a fax. How about a sketch in paint? No i wouldnt let it just hang over with bracing it. I doubt it would tip off because the majority of the weight will be stabilized. i was thinking of just adding to 45 degree supports to the side that hangs over.

[dandy7200]

45's would work as well, although not as aesthetically pleasing if that sort of thing matters for a frag tank.

 

Look at Scott's gallery.

I would think if you put a strong enough 30 inch base under the tank (like a 2 inch thick plank or something), that it shouldn't make a difference if the floor base is only 24 inches. You could also put in a diagonal brace that goes from the overhang down to the floor if you like.

I'd do it.

[BeltwayBandit]

What is your support structure under the tank. 6 inches is no big worry, even with 2x4's.

[Guest alex wlazlak]

just go to homedepot and get a few more 2x4's. theyre cheaper than tanks and itll be fun to build! good luck.

[ReeferMan]

i just laid a peice of playwood the dimensions of the tank and laid it across the stand and it doesnt wooble and i highly doubt the tank will give.

Ah yes....my affinity for pedestal stands

 

fwiw: the one linked above has 12"+ of overhang on both sides, 288gals of water total volume in the tank. Trick is lots of full length sag free cross members and vertical exterior plywood to prevent the stand from racking.

 

Do I recommend such a design, no. Have I done it, yes.

 

For the record, all 3 current of my current stands are pedestals
