    Hi all,

    I'm new here and need info and assistace from you.

    I want to build a tank with L=2800mm, H=1000mm, W= 600mm.

    I'm thinking of using a 40mm for the base and 30mm for the sides.

    I need info of how to keep the centre stable and what type of silicone I must use to keep it together.

    Hello MaLoNaWa. (that is weird to type)

    Wow, that is enormous. Height of 1M will be a problem in the future. Have to put mask and snorkel on to get to something on the bottom. Especially if it is at the back. Also you have to go for Metal Halides because T5 florescence cannot reach that deep.

    Just a suggestion. Make the depth a bit less, like in 800 and make the sump area 200 higher. One day in future you will be thankful.

    There are a couple of guys on the forum who got or had deep tanks. Get their opinions. Like NeilH, Scubaninja and Martin.

    Also by lowering the depth, you can go to 20mm glass that is a lot cheaper and lighter. Can anybody guess what a tank this size will weigh?

    My tank was about 1.1meter deep and I used 20mm glass for the viewing pane

    Riaan, If my calc is correct @ 30 mm: 2800 x 1000 @ 185 kg ea x 2 + 600 x 1000 @ 40 kg ea x 2 + 2800 x 600 (40mm) = 150 kg

    THUS: 600 odd KG, wow...excluding LR DSB etc

    hi

    Hi there and welcome, the best silicone to use is DOW CORNING 781 and its better to go H of 700 and water level at 650 and if you can go at least 700 or 800 for depth and 15mm glass is more then what you need or 19mm is perfect

    Hello and welcome. Wow that's a big tank you're wanting to make. Make sure your floor can handle the weight as well

    I agree with IMarine and welcome MaLoNoWa , 1m in height will also be very uncomfortable to work in.

    Are you intending to run an in tank or remote DSB? If in tank, that will reduce the 1000mm height quite a bit. With a 150 - 200 mm DSB plus 50 - 100 mm water line below the top of the tank would give you a water depth of around 700 - 800 mm

    I personally would go for a maximum depth of 600mm - 700mm odd. This will allow for a saving on the glass as well as lighting! Will also save you allot of heartache or rather backache when maintenance needs to be done inside the tank. Also think if you will be going euro bracing on the top or a rimless tank. Maybe pop in at Idol Marine and go have a look at the new display tank that they have! Will give you great Idea's as well as good advise! If cash is of no issue then go as BIG as you like!!!;) just get it built properly!!
