Finding/DIYing a 40B stand that works for me

So I'm thinking about my next tank expansion project, which isn't happening any time soon, but want to start formulating a plan. I would like to eventually acquire two 40B's during a $1/gal sale (all would be framed) at some point. My unfinished basement is where the tanks would need to go. Ideally would like to make some decent use of vertical space and have them stacked. I don't need anything pretty.

My problem is, my concrete floor slopes towards the floor drain. The drop is ~3/4in over 2ft. That's just in one spot I checked, but gives and idea of what I'm facing.

Something like this might work (65 gal version) and would fit two 40B's plus has leveling feet Aquarium Stands & Furniture: Titan Eze Metal Aquarium Double Stands. Downside is I have a similar kind of stand for my one 20gal and it doesn't feel as sturdy as I'd like. Having two tanks full would probably add some stability. Upside is that if it works, it is not much work/time to assemble.

Then there is this popular plan.. looking specifically at posts #1, #85, and #441. I would assume I would be ok with only the bottom edges of the front and back of the tank (neither side) resting on the frame looking at post #85... or do you need all 4 bottom edges resting on the frame.

To solve the unlevel floor issue with this DIY stand, I could then put some of these (or similar) leg levelers on the stand. Heavy Duty Lifting Leveler | Rockler Woodworking and Hardware Each holds up to 600lbs.

Using this aquarium weight estimator for a 40B and assuming 3" of sand, each tank would weigh ~650lbs. So two tanks would be ~1,300lbs, which would be 325lbs on each of the two front levelers (assuming I let the back of the stand rest directly on the concrete floor). Aquarium Weight Calculator

Obviously looking for opinions of those with more experience. Open to other suggestions as well. Getting everything level is my biggest challenge. I'm also not sure I'm convinced wire shelving with leveling feet will hold the tanks, but I haven't tried it so what do I know.

Well shamrock I for the next would definitely go for the diy 2x4 option.. I have also seen many posts of people using shelving to hold up two 40gB. I own a couple of these shelves that are rated for 1500-2000lbs... And I know I would not trust an aquarium on them!

I think those floor levelers would probably work out fine. As an added safety if you plan on only using them in the front, simply use two levelers on each leg. That will double your strength and safety factor. If you are using 2x4 you will probably have more than one vertical board at each leg, so you'll have plenty of room for the additional foot.

As far as only supporting the front and rear parts of the frame, it may work but I would prefer to have the entire frame supported. It would bother me too much worrying about it.

Why would you choose not to fully support the frame anyhow??

Bump: Here is a picture of the stand I build two weeks ago.... Oddly enough it looks very similar to the thread you linked. I didn't use any plans for it, just designed it to fit my application. It will be clad in solid maple, the trim and cabinet doors are finished I just need to stain and seal everything. I will start a tank thread soon.

Yes, I'm leaning the 2x4 DIY route for the stability. Ideally I want support all four of the bottom edges of the tanks. The plans I've seen just don't have support for all 4 edges (see link to post #85 above). Notice how the vertical 2x4's at each corner, so you can only rest the tank on 2 of its 4 sides. Thought I'd ask the question whether all sides need to be supported. Hopefully someone can give some guidance on how to effectively resolve that in a design.

Stand is looking nice. You'll definitely have to post a picture once you get it finished. I have limited carpentry skills so I really respect those that have the skills and tools to put together a finished stand.

Here is the 40B stand I have now built two identical



Shims ought to cover that slope , I put shims every 6" the whole way around stand, level or not, to keep it off the floor directly.

Very nice work. With my luck I'd get in a hurry one day and trip over the shims! (Limited resources to cut to size without purchasing power tools) Wouldn't want that, especially if I have a stand with multiple tanks stacked vertically.

@Doc7 aren't those clamps from harbor freight such a great deal??? Normally I splurge on really nice tools (over $6k in tools) but those clamps are pretty nice and soooooo cheap. If I remember correctly like $2.99 or $3.99.

Being as you are in St. Louis area I could probably build you a steel stand that would be nearly indestructible, would support the weigh easily, and have adjustable legs. Down side would be the cost of the steel, the bulkyness of the assembly for transport and the fact that steel is ugly :)

This is one I made almost entirely out of 2x4's (plywood sheeting was the only other wood used). All the trim was made out of the 2x4's and everything was glued (no screws).

I buy a couple every time I go to HF. It makes me sick how much the Home Depot clamps cost (5-6x as much) especially because my livelihood doesn't depend on the clamps.
Thanks for the offer, but that'd be asking a lot of effort on your part. The cost of the steel would likely raise the price above what I want to spend too. I'm not ready to build anything yet. Just trying to map out a plan. Nice looking stand by the way.
