    I have a standard 2 foot tank, 60x30x30. It has 4mm polished edged glass. The bow in the long side scares the ##$ out of me. Is this normal and should it be a concern with my tank filled to the top.

    Hi,

    Im not an expert but glass bowing is never a good sign,


    The tank is new.. Drop the level and put the water into the container you had your rock in...

    Maybe riaanp or dallas or 459b can help with glass calculator to check if it may need bracing..



    Strongs and good luck.

    Daro tank?

    Must see how much they bow on a 90L.

    As long as you are careful putting rock in or removing those rocks. It should be fine.

    Would adding a center brace help?

    I would euro-brace it. It's within acceptable safety margins, but only just. 4mm tends to be vulnerable to knocks at the best of times.

    I am going to drain the top 5 cm of the tank for now, would 2 hook over glass braces help? This could also serve as a place to put my light.

    Drop water level and brace the bugger, ,trust me I had a tank 10mm with less of a bow when you start adding pumps etc that rest and push on the glass bobs your uncle. Mine split....

    std daro is 325 high... others 305.. so yes its higher than std but not much..4mm is the normal thickness for std 2foots..your tank is also shorter than std 2foots so where you loosing volume in length you making up on the height... a nice narrow euro brace will not only look good but will also help with snails,etc climbing out...

    Hi sorry I have corrected above it is a 60x30x30cm, don't think it is a Daro since there was no label on. Euro bracing would be nice but I am leaning towards two cross braces of 30x5x0.4cm siliconed on top of the long glass panels. This could then also serve as a place to put my light. What is your thoughts?

    Cross bracing is always a pain IMO.

    Seems that I can only get 75mm wide polished glass so will rather do the 2 cross braces then, would look too clumsy for 75mm wide euro braces. Will empty the tank by 35% tonight, glue them on and fill up tomorrow morning.

    tank is 300mm wide.

    And you want to add two 75mm cross braces? If lengthwise, you got a 150mm gap?

    well now that you corrected the size that is all perfectly normal..no need for any bracing for strength but you can add it for looks,snail safety or as a bracket for light fitting..

    EISH!!! READING AND SEEING THAT.....for the record.... from that picture this thread may or maynot be revived in the near future, i hope for your sake it doesnt.....im gonna state that bracing would be a good idea here.

    yeah bowing is normal....to a degree yes........

    but any tank built should try restrict that from happening. a bend in glass can easily become a SNAP AND WATER WORKS.

    id rather prevent than cure.

    if it was my tank....i would have dropped water level and tried to commence a euro brace.....yesterday
    get a glass dude to gut the width you want

    Lol it will be a 300x75x4mm brace, two of them actually. I want the glass to have polished edges and apparently they can only do 75m wide and nothing narrower. I will place them like this.

    bowing isnt ideal in any instance with glass, i keep reminding people that as careful as you are there will be that one day it will slip your mind and then its tickets, also consider that if you have small children they get up to mischief.. especially around a tank..

    franske i would in this instance brace the sides of the tank by gluing glass strips in the top front to back and making sure glue is applied to the top edge of the size, this will stiffen the side.. obviously drop the water level to about 3/4 or 1/2 first..

    good luck

    i had my daughters friend put a rocking horse muzzle through a tank pane, if it's going to break it'll break bowed or un-bowed, this is the usual bow you see on most 2 foot tanks.

    glass is glass at the end of the day, brace it if you must, it's an overkill in my books...

    Braces in, should help to give some peace of mind. Will slowly start adding back the other water, one concern is I have had it without a heater for a bit longer than a day now, just had a flow pump in the bucket, should this be an issue?
