I'm thinking about raising the ceiling to make it a cathedral type with exposed beams to give me more room above the tank. It probably wouldn't take more than 10 4x6 beams to do it.

ok i was bored and doing some number crunching... you do realize that this "tank" will wieght upwards of 31,000 pounds right? Water is roughly 8.5lbs a gallon and 3600 gallons is like 30600lbs. If that room doesnt have a SOLID concrete floor you're absolutely insane if you try this.
 
The floor is at least 8" of concrete, 5 of which I had poured 3 years ago to level out the garage. The tank is 14,112 square inches, so you're talking about 2.16 lbs. per sq. inch.

That's like a 311 lb. guy standing on a 1 foot floor tile. If you could stack 98 of them, I doubt seriously it would crack the concrete.
 
lol alright cool. Just wanted to make sure you realized the weight of that monster. I know I tend to overlook "little" things like that when I get excited and start a project.
 
Lol, funny Luc. I am going to be working on clearing the garage and sunroom this weekend, so I can move everything except the 210 and 135 out of the fish room. I've been doing a lot of drawings on Sketchup to work out the design. Here's the latest for the bracing and looking at the smaller glass vs. larger acrylic viewing windows.

I guess I should take a before and after pic of the garage too. It might scare people though, since it looks like a bomb went off in there.

The bracing shown is similar to what is used on bridges and train trestles. It uses the left and right side to pull against the back and the back to pull against the right and left sides. By doing so, it keeps everything square.

Looking forward to see this moving. I'm sure I'll get some inspiration of this project. Will be very interesting..cheers, moving off to the krib, working day tomorrow.
 
Something to think about.

Humidity

The humidity in the house is another issue. I recently heard about a man, Mr. 4000, with a 15140 litres (guess!) tank. He had to shut down the whole thing because the moisture was destroying his house. Really scary, but when you think about it, this is just a solvable technical problem. Really big tanks must be sealed off from the house and correct ventilation provided. If you have the skill to build the tank you have the skill to do this too.
The heating/chilling of the water is a question of insulation. Done correctly it won't cost too much in terms of power and it won't affect the temperature in the house.
 
Already on top of it. The room is off of the main part of the house, its roof is equipped with a power ventilator that I can run duct work to. I'm also going to have a dehumidifier. I'll probably paint every surface other than the slab with Kilz and seal the slab with a few coats of waterproofing before I begin construction.
