Is this level enough?

What size tank?

Other than that, I'd say your good.

 

[Ebslinger]

I would have to agree with @Flippers4pups. Over a short span, small tank, not a huge issue.

Over a 5 foot span... issue.

Just my two cents.

 

[bdare]

Uh oh.... it's a 220 72" long

 

[bdare]

For the record... I did a leak test. Can't see the waterline. Just worried about structural integrity.

 

[Ebslinger]

For the record, I'm not an engineer. However, a tank that is not level will likely exert more force on one area of the tank. Will that exceed the design specs? I don't know.

That said, 220 gallons of water is a lot of water...

The question is, risk vs reward.

For me, I would try to shim it a little.

Just my two cents though...

 

[Jon Fishman]

I agree. I would shim..... when it comes to 220g of water in your house..... if ya gotta ask.......

 

[Flippers4pups]

This is why I asked. If you used a 6 ft level, I'd say okay. If it was a 3 ft or smaller level, it could be a problem.

 

[bdare]

Ok. Thanks all! Will shim!

Can 4 or 5 of you come over and help me lift this thing?

 

[Ebslinger]

I've actually used a floor jack and a lever before when I was working for a large install company... just a thought.

Is your tank rimless?

 

[bdare]

Is your tank rimless?

No. Has a canopy.

Pretty sure that contradicts physics. Liquid in a container exerts equal force regardless of the orientation of the container. Being out of level will not exert more force on the low side.

My biggest concern would be one overflow lower than the other. Aside from that, if it looks ok, I wouldn’t worry about it.

My 2 cents with a degree in civil/structural engineering. The two most common types of loading are uniform and point loading. The glass of your tank is undergoing a uniform load, distributed evenly across the entire bottom pane of the glass. It then depends on what you have under your tank.

If you have a piece of plywood under the entire tank, then all of that force is evenly excerted onto the plywood.

If you have a perimeter support and a cross brace, then the uniform loading across the glass is transferred to the outside supports and cross braces times the area. So if you have 2 cross braces, it's 1/3 the total uniform load on the glass spread to the beam and girders (perimeter and cross brace)

All of that force is then transferred to a point load on the vertical members (columns) of the stand.

As long as your stand is sufficient to hold the tank and contents above it, a few degrees off won't cause the stand to fail.

Now as far as the vertical panes failing, that's up to the manufacturer who should have designed the tank to hold the volume of water it was meant to hold.

That's all structurally speaking... if you can live with the waterline not being parallel to the top of the tank. I'm OCD, that would drive me nuts.

 

[bdare]

Thanks for all the feedback. The tank is made by Planet Aquariums. It's very well made.

Also just one slim external overflow box in the middle.

 

[Ebslinger]

Regardless of the debate, it's a great looking tank! Can't wait to see the build thread!

 

[Aardvark1134]

You will find most levels are off by more than you show there.

 

[SeaJay]

No. Has a canopy.

Good looking setup. I’d fill’er up.


Who made the stand?

 

[dadnjesse]

I would think your stand would be better off flat on the floor rather than sitting on those shims
