    Hi guys,

    I am in the process of info gathering.

    I am looking at building a tank 1500(l)x600(w)x800(h) I need to build it with 12mm glass so I believe I need some bracing. The bracing I have included is all 50mm wide and 10mm thick.

    I have attached a pic and a Sketchup model of what I was thinking.

    [​IMG]

    1. Should I put 2 cross members across the top dividing the top area into 3 equal parts?
    2. Should I do the same on the bottom?
    3. Can I use 10mm glass for the bracing?
    4. Is 50mm wide enough for the bracing?

    Thanks for the assistance.

    You don't HAVE to use 12 mm glass

    I have a 1600 x 700 x 600 from 10 mm glass with a 10 mm brace 50 mm wide and its plenty strong enough.

    10 mm will save you some bucks to.

    Welcome and hope you enjoy the hobby. Just a suggestion. There are some really good cheap tanks the same size as you are wanting to build. Look in the classifieds. Just a suggestion.

    Also, I made my first tank 800 high. If you are wanting to keep corals and things its way too deep. I battle to move, place and manage my things in the tank. I would not go more than 700mm

    Any articular reason why you are going 800mm deep? Bear in mind that you will need to work in the tank from time to time and it really is difficult reaching down to the bottom at that depth.
    Notwithstanding, it does allow for good scaping potential: Corals can be moved closer to your light source as a function of scaping and the depth does allow you to keep a larger diversity of corals

    This is good to know. All the calculators I looked at told me even 12mm was a risk... Perhaps it has something to do with the height of 800mm ..?

    Thank you ... I had a quick look at second hand tanks ... the problem is I also wanted to try to make something myself from some 12mm glass I was given ... just not enough for the full tank.

    Thanks - I am feeling really welcome .. nothing like an active forum to make you feel comforatble.. ;)

    This is good advice .. I really don't want to battle ... I do like the depth though as it gives a feeling of more space for the swimmers (I.e. they looked less cramped) but this is really just my impression ... I take your point about it being a PITA to manage and maintain.

    The only reason was for the deeper tank is as I said before... I would also like to scape some nice pinnacles .. but I could also do that in a tank 700mm high.

    You guys have given me even more to think about .... thank you!

    Thank you man.

    One question (another one that is....)

    Are the long braces on top of the front and back panes or level with them (inside the tank) with the shorter ones on top of those?

    I don't suppose you have a photo of the bracing on your tank do you?

    Thanks again
    Sean

    will post a pic tonight.

    my long brace runs onto of the short braces and its 10 mm down from the top of the tank so I can have two pieces of acrylic on top as a lid to close the tank.

    Just another question or two ...

    How do I work out what size plumbing I need?
    What size pump... 5000l/h..?
    Where would you recommend i place the overflow ... In the bottom with a standing pipe or on the back with a bulkhead..?

    Many thanks

    use 50mm
    Always.
    Can get the fittings anywhere.

    What filtration option will you use?

    Do you want a skinny overflow? An old style box corner overflow? Will the euro bracing go over the overflow? Can you get something out with bracing in the way? Linear length of the overflow? That is linked to your return pump rating. Overflow teeth/comb? or not?

    Thanks for the quick reply Riaan,

    50mm it is then.

    I was looking at having a DSB in the sump after a skimmer. Pump to go in a chamber on its own after the DSB.

    In terms of the overflow I was thinking of either drilling the bottom of the tank and installing a stand up overflow with a dirso..?? Behind a corner panel with slots in the top... Or ... Just drilling the back of the tank and fitting a bulkhead which I will cover with a slotted cover.

    But it seems I am not reading enough as I just keep getting more questions.

    Cheers fo your input

    You need a double layer for the base 2x10mm or 2x12mm as well as the bracing.

    I haven't seen this mentioned anywhere but my wife regularly tell me I'm blind. :coolgleamA:

    Bendor, thanks for this...

    This is the first time I have heard of this. Is this needed even if the tank is installed onto a solid base ..? Not just an open stand?

    Yes. All the upright panels take varying amount of pressure from the top down as the water gets deeper. The bottom pane takes the weight of all the water, substrate, rock, the other glass panes and then it gets put onto a surface that even with thick rubber covering could be slightly uneven and it has to withstand this warping as well.

    I've never built a tank myself I've just read the other guys threads for fun and my own education so I'm sure one of the DIY kings will wade in here with some serious advice by tomorrow morning. As long as you're not planning on building it tonight?.:thumbup:

    In my opinion I don't think its necessary to have double 12 mm base on a solid platform.

    Here is the photo of my bracing. sorry took a so long
