    Hi Everyone - I've just posted this same question to Hennie but I'd love to get some inputs from you guys as well - So here goes


    I'm planning a new reef - I've been collecting everything I need to start over the last couple of months and all I need to do now is the stand - the second hand tank I bought has a stand that is too low and I have to weld a new one.

    Heres a bit more about the system Im planning - tank dims are 2m x 50 wide x 70 high - sump is 1.5 x 40 x 40. Everything else is standard - the space where I want the tank is the challenge.

    Here is a pic of the location in my hallway.

    [​IMG]

    The space is 2m(well 197cm - will have to grind 3cm off the wall) x 70 deep.

    So originally I planned something like this

    [​IMG]

    This is what I want it to look like in the end.

    [​IMG]

    This is the stand that I have in mind now

    [​IMG]

    Its built out of 50mm squaretubing(3mm thick on main beams and 2mm thick on supports. The main goal here is working room under the tank - I hate not having room - becuase the tank is in the hallway it will be 1meter high. Becuase the hole in the wall is 70cm deep and the tank only 50 I want the sump to not be right under the tank becuase I would be wasting the space behind the sump - SO - I want the sump against the back wall - hence no supports in the middle back and front - only the one in the middle. The sump will fit between this support and the back wall.

    Will this stand hold - is it overkill? Obviously the less metal etc etc the better so if its to much where whould you scale down or would you do the whole thing differently - One guy here in Pretoria told me that simply a squaretubing plain boxframe would work - I think the 1 ton tank would be too heavy - am i right

    Thanks for the help guys!

    Would that centre brace not be in the middle of the sump? Can't you put more horizontal support round the side?

    Maybe you should move away from steel tubing and start looking at i beam.

    for maximum space, you could also leave the hinge doors off, i saw an excellent concept the other day. Instead of doors its a removable panel. It has pins at the bottom of the wood which insert into small holes in the bottom frame and the mechanism that hold the panel into the frame is two push buttons on either side at the top, when the buttons are in, the mechanism locks the panel in place and when the button is out it pulls the latch in and then you can pull on the button as a handle and the panel comes out.. I thought this was ingenious and wished i could redo my cabinet.

    Maybe channel iron as uprights and i beam as cross beams. and square tubing as support beams between the i beam cross bars.

    you could maybe even design it in such away that your pipes are mounted in the I beam at the back. out of sight. You could also put your electrical sockets in these spaces. I or H Beam on its side.

    i used 25mm and 40mm angle iron, all the 90deg angles make for extra strength

    You are running two treads for the same thing at the same time. Ask Administrators to combine them.
    Anyway as I said in the other thread, the bar at the top of the middle support will take all the weight of the tank. This bar will bend like an unhappy face. The rails will then bow out downward in the middle, causing the tank to go crash, leaving you with the unhappy face.

    Just remember, you will put all the weight of a 2m tank on the 4 corners. Thats it.

    Are you sure, 100% sure of the floor, you currently have tiles there. Are they staying or going? No empty spaces under the tile where tiler did a crap job?

    Somebody else if my memory serves me right did answer you before, where he did a new concrete slab because on his previous tank, the floor gaved in...

    If it was my choice, nope rather not. Distribute... and spread the weight / risk

    christiaan, they are called machine feet, the only thing with raising the stand is that it now more than even needs to be level
