silicone it back, probably cause by warping of the glass. Might want to looking into the matter seriously
The centre bracing of my 4x2x2 dislodged when i cam home from work today. Anyone could advise if there is any cause for concern? although the side bracing still seems quite secure. Also is there anything i could do about the centre bracing.

Just siliconed the tank back. Hopes nothing will happen.
I think if the tank is new,you might want to contact the supplier and let him know.At least if something does go wrong, he is made known of this matter.
Unfortunately the tank is already 5yrs oldOriginally Posted by tropic

That means the silicone life span is approaching or something is making it 'aged' faster. It could be the heat emitting from your light source.

Errr... did you partially empty the tank before siliconing back? You should because it will reduce the warping first. Only top up again after the silicon has completely cured.

I suspect it could be a sign your tank is already warping. Please seriously consider removing atleast 50% of the water, all if possible, immediately. When you try to silicon it back, and the distance is between the tank and the bracer is too far, consider replacing the tank.
i removed 3/4 of the water before silliconing it back. the thing is initially before removing the water there is a gap between the support and the brace.But as more water is removed the gap narrows until i can place the brace on the support. By the way how tell if warp because except for the centre bracing that dislodged at the rear pane of the tank everything seems normal.

Stand at one end of the tank, and look along the top edge of the front glass panel towards the other end. The top edge should appear to be straight. If there is warping, you'll see a curve. Do the same for the back glass panel, though logically, either both or neither are curved, never just one or the other.

I would advise you to replace your tank, not worth the risk.
But is you INSIST on repairing, please note to clean the glass as much as possible(removing all dust, old silicon etc), and using sand paper abit to allow more grip for the new silicon, allow it to cure for next next 24 hours before adding any water to the tank.
Vinz,
I didn't understand your logic though. How would you assume its either both or neither?
as nobodies asked, what thickness of glass was used to make your tank.
if it was 10mm you shouldn't get a problem like this but if it was 6mm then you will see warping.

Happened to me before... Lowering the water level will reduce the pressure on the glass while the brace is being siliconed back and the silicon cured.
However, do seriously consider shopping for a new tank in the mean time. You had witnessed a bad warping, and it can happen again, and might then cause a major leak.
I replaced my old tank within a few months of the bracing falling into the water...

Oh, juggling is hard work, man!...
The tank is 10mm thick and i be looking for a new tank
just a thought:
will "single piece" glass tanks take the pressure much better?
since there are no joints no silicone nothing
whats the biggest size these tanks can go to?
don't seem to see them come in anything bigger than a 2 feet
additional information for you.
i have a 4 x 1.5 x 2' tank with a similar incident.
the bowing i measured was about 15mm at the centre.
so i suspect the bowing for your tank will be greater.
clean bothsurface to be siliconed together.
that happened a year ago and it is doing fine.

The front glass and back glass should be the same thickness and strength. The water will exert the same pressure on both pieces. If the water pressure is strong enough (or rather the glass is not strong enough) to warp the front piece, it will warp the back piece equally too. If it is not, then neither will be warped....
Vinz,
I didn't understand your logic though. How would you assume its either both or neither?
I don't think there'll be much difference. The warping is due to water pressure on the glass surface, not because of pressure on the joints.

yeah... okay
my point was that since there are no joints to speak of on those single piece tanks, then what effect does the warping have on these kind of tanks? no joints how to leak? through the glass?
then also very curious why don't see big single piece tanks? is it not feasible? due to what? technology not advanced enough to make such big item out of single piece of glass? not likely mah i think or is it cost?
haha very curious here

Sounds logical but I do think practically, its impossible to have two piece of glass (or even any other material) exactly the same strength. So the one that lose out will definitely handle more pressure than the other.
Just my thoughts though...
I don't really understand the meaning of single piece tank. I saw some smaller curve tank with one side silicon only, are those single piece?
