I have to agree. It is a good idea but not pratical. Stands work beacuse the pressure of our tanks is speard out over a big surface. haveing 3 main points would put alot of stress on the ground in those areas. Also if it happens to have any flaws at all, like chompers said, u or sum1 else may die or get injured. Maybe re think your desing a lil bit and test it as Chompers said. and if u were to do that it would be waaaaaaaaaaaay too top heavy. and wobble at all might cause it to come crashing down. Also u have to figure out how much your floor can support and if it is level.
It really makes my day to see someone that gets it

Thanks
I could never do this in my room cuz i have a slight slant for sum reason to one side of the room...
Since you are in California, it could be from several reasons:
1. During earthquakes, the ground can be described with having liquid properties. The difference in ground densities from one end of the house to the other could allow raising or sinking in parts of the house.
2. If your house is built on stilts on the side of a hill... Gravity always wins, need I say more.
3. If your house is wood frame with a basement, the sill plate or beam that your room is sitting on could have some decay.
None of these are anything to immediately worry about. It is just food for thought.
How much can cinder block support?
A bunch. I don't have the numbers and I can't get to my books to look it up. In a week or two I will post it if no one else does. They are stronger with the holes up and down rather than sideways.
How steardy are cydler block stacked?
They are sturdiest in smaller stacks. The foot print of each block is wide in comparison to its height. Each block unto its own is very stable. As they are stacked, they lose that stability. The footprint to height ratio is reduced dramatically. Think of leverage. The taller the stack is, the easier it will be to topple.
How much is the tank going to weigh?
8.3 pounds per gallon, and 7.6 gallons per square foot.
