A king size water bed must be around 300 gallons of water. 1+ ton. Wow, and with some action, I'd rather leave it downstairs.

Just take into consideration that a 180 gallon tank will not reach 1 ton.

See tank calculations above, gross wght 1850.87lbs or aprox 1851lbs +/-.
Now add the stand,hood,lighting,filters and ect and its easily pushing 2000lbs or one (1) ton. If I add more substrate it will very quickly be over that mark.

Chille...

I think you found your answer I would make some home modifications or just place the tank on a nice STRONG concrete surface .

Could you run some sort of bracing up the wall in back of the tank, or to the cieling, or both? That is, without it being totally ugly? You might have to build some sort of trim arround the bracing, but that might give an aestetic "psudo-in-wall" look. Depending on where you live, some cielings/roofs are rated to 150-200 lbs ft2(usually in high snow areas, not sure if mobile is or not:huh: ). I wouldn't put all the weight into that, but mabe it could help distributr it out a bit.

I calculated my tank weight and it goes aroung 1291 kg (2840 lbs) without the stand. Can reach maybe 1400 kg total, including the hood.

the calculations made on that page seem a little overexagerated to me. You must be able to reach 1" of gravel with around 75 lbs. i'm no engineer, I just calculate it by my experience.

I believe that adding subtrate will not rise the tank weigth a lot since it will displace water which is also pretty heavy.

Water weight 180 gallons @ 8.32 lbs/gall = 1497.60 lbs
Glass weight @ 1/2" = 304.00 lbs
Gravel: (7.5gal or 1732 cubic inches) = 92.00 lbs
TOTAL = 1893.60 lbs = 860 kgs. (1 kg = 2.2 lbs)

You'll need a 140 kg. (308 lbs) stand and hood to reach 1 ton. Also, this is counting you'll fill your tank to the very top, with water almost overflowing.

Also, I don't think you'll need 1/2" glass for a 24" height tank. I believe 3/8" will be enough and you'll save some money and extraweight. Accordinf to the online calculator, youl'll pas from 304 lbs to 227 for glass only.
