33 dollars, 1 hour = stand for a 150 gallon.

  • We are currently upgrading MFK. thanks! -neo
I don't see that many screws. IMO definitely not enough, I'm always down for over-doing it on a build. Especially one that is to support such weight. We are talking at least 1500lbs when the tank is full. That doesn't include substrate or decor.

Either way I wish you the best of luck with your new set up.

From my post with the instructions:
kallmond said:
When I screwed the top-rail to the legs, I put only 1 screw in each leg until I had the bottom (flat) 2x4 in place, to ensure I could make each leg perfectly square. Once that was done, I went back and added 2 more screws to each.

The way the stand is built, there are 6 load bearing legs, with 2x4 runners braced to them to spread the load. A 150 full weighs 1800 lbs. http://freshaquarium.about.com/od/aquariumsandstands/a/tanksizesweights.htm

1800 lbs, spread over 6 legs = 300lbs per leg. It's your supposition that a 2x4 on end can't hold 300lbs?

In fact, this stand IS overbuilt. I doubled up the 2x4 legs. Which (in a purely mathematical vacuum) means 150lbs per 2x4. Is it your opinion that a person balanced on a 2x4 would crush it?

I put 3 wood screws at every junction, at different angles, plus fully coated the entire joint in liquid nails. I knew this build would bring out the "overbuilders". I'm all for it, if you own a lumberyard. But I wanted an example of a perfectly sound, reasonable stand on this site.

Today the tank is full, with substrate and rock decorations. Sitting up there like a champ.

As a last question, has anyone ever bought a stand for a 150 gallon tank? The ones in the store were made of 1/4" plywood with 1.5 x 1.5" braces inside. By all definition outside of MonsterFishkeepers, my stand IS overbuilt.
 
Like I said I wish you the best with your stand. I hope it lasts a lifetime.
I personally wouldn't trust liquid nails.
You're right... Compared to some store bought stands yours is over built. But if you all you wanted was a pat on the back for building a stand quickly and cheaply then why didn't you say so..

I was only offering a little constructive criticism... From a dude who has built many stands, racks, ponds, and muti tank systems......

How's the stand holding up man?

I went to lowes, picked out 9 of the straightest 2x4 studs I could find, and rolled my cart back to the lumber cutting area. Normally they charge you $1.00 per cut, but I've never actually had them charge me. I just strike up a conversation with the guy behind the saw. They've always been cool about cutting lumber for me.

3 2x4's he cut into 2 34.5" segments each, leaving a remainder piece.
2 2x4's he cut into 3 31" pieces each. The remainder was like 2.5" long, so I tossed that.
4 2x4's he cut into 1 72" piece and 1 16.5" piece each.

My cut lumber list:
4 72"
4 16.5"
6 34.5"
6 31"

I was doing the math in my head on the way to lowes, I made two mistakes. The 16.5" pieces should have been 15.5 (the stand ended up being 19.5" wide, not 18.5 like my tank), and I should have had him cut the 4 "remainder" pieces from the 34.5" cuts into 4 11.5" lengths to go on the bottom between the front and back.

I screwed 1 34.5" piece to a 31" piece, leaving me a 'shelf" to set my top-rail 2x4 into.

This is the inside of the front. On the outside, it's flat. (So eventually I can put a piece of cabinet grade oak plywood on the front)

I measured 36 inches down the 72" piece and made a mark. Then 1.75" on the width of the 2x4, and made another mark. Then just line up the marks to make sure the middle leg is centered.

See how there's nothing holding the bottom straight? That's where I should have used a 11.5" piece of scrap to go between the front and back rails on the floor to keep them from spreading or pinching together.

I added the longer scrap pieces I had diagonally to attempt to hold the bottom rails equidistant from each other. It'll hold, but for "security" sake I'll go back through and make center braces for the bottom. For those, I'll lay a 11.5" piece (remember my stand is actually 19.5? So for me, those pieces will be 12.5") between the rails, and then cut a 19.5" piece to go over that to attach all of it together. Those photos will have to come later.

Now, I have 2 openings in the front, each 30.75" wide and 31" tall. In Lowes, they sell unfinished cabinets. An oak "upper" cabinet that measures 30" high and 30" wide and 18" deep is $70. In the future, I'll get 2 of those, one for either side. Fit them in the openings, and then put a 1/4" oak plywood veneer sheet around the whole thing. A little espresso colored stain and it'll look like Paid $1200 for it.

Stand looks great. 2x4s will hold way more vertically than people give them credit. Only thing I would mention is to give yourself another 2x4 in the back for horizontal bracing.

My reply came across much more defensive or cocky than I intended. Pls chalk it up to that being a bad day of dealing with he ex-wife and accept my apology. I love the level of expertise here at MFK, and I love that I can come here and post a question and get a huge array of constructive answers.

I too have built many stands, tanks, and racks. You can tell from my join date I'm not a newbie at this, but I posted this to show that you can build a functional tank for much less than what the average MFKer appears to spend, with very few tools. The 150 was a craigslist purchase for $80 (I think.. maybe it was $100). I found a pair of AC110's (actually older AC500's) on freecycle. I used playsand and 10 gallons of crushed coral (also from freecycle). The heaters were a trade from someone with a broken tank, I traded a 55 gallon for a broken 110, 1 light fixture, a Rena XP canister and the two heaters.

All in all, including stock, I have under $200 out of my pocket in the setup, and most of that was spent over time. The reason I posted this thread was to show that you CAN be a MFK without spending thousands, or even hundreds of dollars if you plan, and work at it.

rdKirby, the stand is holding up great! The tank is full, rocks stacked, and 6 happy (baby) inhabitants (Filter media from other well established tanks).

Pharaoh, you're right, horizontal bracing is needed. In a couple weeks, I'll be shrouding the stand in plywood, which will give the needed lateral rigidity. Until then, I'll have to keep an eye on it.

Have you ever looked at the structural integrate of a stand build by a manufacture for a strander 180gallon They do not even use screws they staple it and its made from particle board not eaven 2x4's , And did you know the shear strength of a screw is about 1,000lbs per screw with that said his stand is overkill a gallon of watter is 8.34lbs the glass tank is 250lbs so lets say 100lbs of substrate + tank + watter = 1601 so its under a Ton when simply 2 galvanized screws can handle a ton speaking shear off strength . Your stand is rock solid I plan to build in the next couple of weeks for my new 180 and im not eave going to double my vertical 2x4's
but I will add sway gussets to the back and sides since my young kids like to get bat shi* crazy and push on the tank instead of just looking {Kids?}

Horizontal (or better yet, diagonal) braces across the back like / \ would be a great addition. The reason to double up on the 2x4's wasn't for strength, it was to transfer the load from the horizontal 2x4 'rail' to the vertical post. My rail sits on top of 1 2x4. All the force is directed downward directly to the floor. If you screwed your post to the rail, all the weight would be trying to sheer the screw.

Here's a picture of the top rail meeting the post, and why it's important to double up the 2x4 posts.
