    Hi Guys

    So I asked you guys for your input on tank dimensions I was thinking of going with and I have finally settled on what I want. I will illustrate the dimensions in the picture below:

    [​IMG]

    If you feel there are any issues with the dimensions above please let me know. The Tank height is 650mm and the stand height is 900mm


    With regards to the stand I was thinking of going with 32mm (2mm wall thickness) square tubing. Below is 2 pictures to illustrate this:

    Do you think the Stand will be strong enough to support the 650 liter Display Tank & Sump etc? What alterations would you make if any?

    Thanks
    BushBaBy

    Oh Yes BushBaby! I am quite sure that if you don't leave out ANY of the legs, this stand would be more than strong enough to hold your +-650 litre (plus sand and live rock - so, ending up more like +-900kg) display tank....

    So you don't think any of it is overkill? Also are the dimensions I settled with ok?

    (also only started using sketchup today so excuse any issues in the diagram :))

    I am no engineer, quite far from it actually, but dependant where your sump will be lcated, I would advise losing one front leg to facilitate easier sump acess.

    Yes. It MIGHT be a bit overkill, but rather overkill than too little....... So other than that, your design looks good. As long as your tank won't be TOO high to work in from the top, though.

    You should think of this - you design the space below your tank (at the bottom of your stand), for your sump and filtration equipment. But, the stand should not be too high that you cannot work in the tank (from the top).

    Like Ivan says loose a leg but maybe replace it with a 45 degree somewhere in the back

    That is overkill
    Adding gussets and you can drop most of the inner legs. Leg in middle on short side. Leg in middle at the back, leg left middle in front, and the central leg.

    And you need support to carry the sump on the ends.

    Something like this?

    So you guys would recommend something more like this:

    [​IMG]

    Would the above be ok? Is this what you were suggesting?
    Would 32mm still be ok?
    Do I need to add gusset plates, cross beams or small 45 degree supports?
    For the Sump - Should I remove the bottom bars completely and design it around Sump dimensions or should I just add extra beams? Also would a sump with the dimensions 1390(l)x450(w) not be a better options as those support beams should work for it?


    I plan to have removable panels or doors on the left and right side of the image/stand.

    That's how I would have designed it, but I'm not a tank builder.

    Sump either a big cube with the smaller cube area used for a RO storage/ATO, or a tank as you had in mind with the left over space for a RO storage area with ATO.

    What are your ideas for the overflow and sump return?

    If you are going with this design, then I would rather "err on the side of caution" and re-enforce all the corners...many will say it's overkill but honestly...not really much you can do once the Tank is up and running...I've got a 650x650 and mine is made of 50mm square tubing and my corners are re-enforced...:blush:

    or stick to the current design and go with a slightly bigger material size? (rectangular tube or larger square tube?)

    looks pretty solid for 650lt... i have seen 1000lt systems on less ;)....

    There is nothing wrong with that design, as long as is is manufactured properly and is fully welded to strengthen and seal the tubing.

    I always close the legs, then drill and tap to take an adjustable foot for leveling.

    Maybe check the height of your bottom brace and make sure you can get underneath for cleaning.

    Good luck!
