Any Engineers out there?

Super thick acrylic won't be needed. The plan is for a 360 degree viewing area, but that's not to say it wouldn't have supports. The thought is to use stainless steel window framing bolted to the floor forming a box. The top of this box would be welded together and supported against the floor above. So normal glass thickness for the depth shouldn't be a problem.

Keep in mind a 5-6 height on the viewing area would still require a relatively thick piece of acrylic. I would call around for quotes. Once you get over 1" thick, the prices skyrocket.
 
The "cold joint" as you say, sits on the footers. So for that to drop, the whole wall would have to drop.
Right but you have a joint between the wall and the floor. Usually they pour the footer then the walls, then the floor inside so the floor would abut the wall and where that happens there would be a cold joint. Not saying its going to "fall" but a potential leak that will be hard to seal without something thick an very flexible.

The concern is that the floor could crack under the weight. This is looking like the deal breaker. If the floor was 4-6 inches it would probably be fine. My own floor in my basement turned out to be 3-4 inches once I started drilling on it. It was okay for my tank but probably not for something to this scale. Its possible to pour a new floor and/or interior walls, but then the cost will skyrocket.
You really need someone to come in a possibly to a core test on the floor for its strength. Most basement floors will be poured in a 5-7" slump for "self leveling" but this weakens the concrete.

62.33 lbs of force per cubic foot. Span that across your entire floor and depending on the base and the concrete mix, it might be a disaster, it could also work and be just fine.


Pleas by all means though, no one will know for sure until you fill her up!!! Pictures and Online Streaming Video Please
 
Once the basement tank is finished:
1)Drill hundreds of 1/2" holes in the floor of the upstairs bathroom
2) Fill bathroom with bio-balls
3) Install a 4" 10,000GPH 5HP Water pump and run a firehose hose up to the bathroom.

Voila! DIY drip filtration!
 
Why stop at the basement? Do the entire house, and put giant acrylic hamster tubes through the house for you to walk around in.

This isn't going to happen. We're doing another ridiculous unrelated project instead.

X2... I work as an engineer (not licensed tho) and all weight/strength issues aside, I don't think you'll be able to get a sufficent seal between the floor and the wall. You may get it to hold water initially, but not for long and its not a "tank" that you're going to be able/want to drain and patch every few months. The cost vs. longevity would keep me from doing it. You may want to check out ANYTHINGFISH's website, one of his friends built a big concrete ray tank in his basement (in one pour). This would be one way to get a strong, water tight, tank...

Also, the moisture IS going to be an issue. I forget exactly what you said about sealing the ceiling of the basement, but that amount of "hot" water (relative to the air) is going to evaporate fast and put a lot of moisture in the air. All that moisture will seep into just about anything you use on the ceiling and once it hits the ceiling of the basement/floor of the house, its going to condense (assuming you keep you house below ~80 F) and causing water damage/rot to the ceiling/floor... A massive amount of air circulation would solve this issue, most likely, but drive up your heating costs...

But I do love the idea. :headbang2
