    Hi I am currently planning on building a shallow reef setup. I would just like some help regarding the thickness of the glass. The tank will be 150cm Length by 50cm width by 45cm Height, I will also be drilling the tank for a overflow. I would also like the tank to be rimless. Any ideas? ;)

    hey dude,

    Here's a chart to help you out- a always go 1mm thicker, just for safety sake!!

    to be honest, im not too sure about the rimless build- im a fan of bracing!!

    Also you can go to Calculate Aquarium Glass Thickness | Aquarium Tools which has a cool calculator for u.

    Hope u come right.

    Thank you I was thinking about 7mm sides and 8mm bottom, do you think that is sufficient?

    Im no expert, but know that spending a bi of extra cash on thicker glass, may just prevent crises later!!

    personally i would go 8mm and 10mm for the base... overkill? maybe, but again, rather safe than sorry!

    i would personallly go 10mm for this construction if not 12mm (always better to go over spec on the glass.

    i have a 1.5 x .700 x .400 in 10mm and it bows a little aswell, but you have only a .500 depth with a .450 width..

    when using wavemakers etc that extra 4mm bond is very important. i see on international forums they say we loose 30% of tank lifespan by going rimless owing to more pressure being added to the joints (in the absence of bracing) how true this is im not sure.. and if wavemakers are used im sure you will want that little bit of extra piece of mind..

    i have done tanks in these sizes in 6mm before but well braced..

    Just a technical point. "Rimless" is when the water flows over the rim of the tank into a catchment tank.

    Braceless is when tank has no top braces. eg no euro bracing.

    Has difference got an impact on glass thickness?

    YES.

    This is because the two water heights are different. The braceless tanks water height is normally about 40mm lower than the water height of the rimless tank.

    If the glass height is 450mm and the water height is about 400m 12mm will be safe. 10mm will also be ok but nearing the uncertainty zone.

    The base thickness will not change and 10mm will be OK.
