    Hey guys...firstly this is my 1st ever thread and blog chat...so here goes..

    I started the fish tank love with a 60liter...had this for a while and then decided to jump to a 100liter ...

    Recently I've been making my 400L aquarium...

    I asembled it and, well set it up and cycled it, and then it leaked...all 400L's leaked out...it was a desaster 1:30 am n four hours of work to mop up all that water...

    Any way I found the place it leaked and it looks like it broke the seal of the silicone right through and that's where the leak was, it was so bad I thought it was going to burst...

    I stripped all sides of the tank, removed all silicone, about to assemble again...

    Any tips on how I cn prevent the initial crisis from happening again ?

    How much wieght can I putinthis 400liter custom tank?

    What's the ruling for the surface to water space ?

    :welcome6:

    Any tips on how I cn prevent the initial crisis from happening again ? Well use bostik marine silicone & make the beed about 2mm thick between the glass & tape it down then leave to fully cure for two days.

    How much wieght can I putinthis 400liter custom tank? Depends on thickness of your glass...

    What's the ruling for the surface to water space ? What rule? Mine is 15mm from the top of the tank to water surface.

    Thanks man I really appreciate this help,

    Just as well I bought the marine silicone from bostik at builder warehouse yday.

    Will do the 2mm bead layout...why not .ore than 2mm ?

    The glass thickness is 6mm

    I'm sure mine was also about 15mm...

    Thanks for the speedy reply....

    2mm is fine more than that is a waste IMO.

    6mm? that's thin for 400L maybe add some bracing for extra stregnth as 6mm will break easy. You'l have to be extra careful when adding live rock & scaping as one slip & there goes the glass.

    15mm is fine then..

    Yeah well gota help fellow reefers...

    @Bilaal I also have a 400L DT, but Glass Thickness is 10mm.

    Not EVEN CLOSE being a expert at this, but 6mm glass does seem a bit thin??
    @RiaanP do you have any suggestions on this??

    I agree with MistaOrange,6mm sounds inadequit.Use the formula on www.theaquatools.com and enter your dimensions to get an idea of what size it should be.Depending on the depth I would brace it like crazy or alternatively purchase the correct thickness glass.Remember the deeper you go the more pressure is transferred to the lower part of the tank,especially the bottom.I would rather play it safe and build it stronger than recommended,breaststroke @01:30 am in the lounge........NOT FUN!!!!

    a bit on the thin side.

    check at the bottom of Marine Aquariums South Africa calculators
    there is another glass thickness calculator.

    you do not specify the tank size, but to be 400l I reckon you got a 1.5m tank by 500 by 500mm, that would be about 400L

    The calculator recommend 8.2mm for the sides and 11.3mm for the bottom.

    Unless you brace the up the sides as well with euro bracing top and bottom.

    With the deflection you got, it was more than the little bit of silicone on the edge of 6mm glass can provide. Adding glass strips in the corners will greatly increase the grip power of the silicone on the panes.

    I've seen a tank this size made with 6mm. It worked but was braced properly.and the owner was always extremely careful working on the tank. And no kids allowed. Or any fool who want to knock the glass to see if the fish react.

    I did research on the size already n 6mm worked out fine....

    The law is you can't go higher than 120cm with 6mm glass...

    I tried the calculator thing now...not working should I use it on a pc rather than on a phone ?

    What about uneven base or floor


    Thanks guys...I really like how u guys r helping

    N.B the tank is already made cut and almost siliconed...keep this in mind....


    What brace r uguys refering to

    Uneven base or floor will crack the tank quickly....

    do not confuse normal building codes for household windows with tanks. Houszehold window do not have to hold back a wall of water.

    120cm is high!!! Tank that deep and you can dive into it.

    1.5 meter tank with 6mm glass i would really not reccommed that size glass.. my tank is 900mm with 6 mm glass and when i filled it without bracing the tank stretched in the middle by more than 1 cm and there was so much pressure on the glass.. i then had to put a single 10cm brace accross the width of the tank... i would suggest just going for 10mm to be safe and not to have to worry all the time about the tank deciding to break down..

    and there is noways that even 10mm will withstand tank pressure from 120cm high tank

    6mm glass is way to thin. its going to break even with bracing. @ 120cm high i would rather have suggested that you use anything from 15mm to 20mm of glass and then still put on bracing. then maybe i will feel that i wont be swimming in my own home
