you have a 171.1 gallon tank...and yet the "G"lass is only 0.48 inches thick.

I have a 100 gallon and the same thickness glass. I have seen a 125 and measured the glass and it was the same. It's sounds a little thin to be on a 170+ tank...but I figure that if the top is braced against bowing...like in the middle, or more...then I would suspect it would be fine...but I too would be a little worried. My big question is did you buy this tank or did you build it? If you bought it from a company that makes aquariums (not just terrariums) then you should be fine, after all they have done this before. But if you built it yourself then I would have gone for thicker glass...and sacrafice a couple of gallons for piece of mind.

thanks dave...
as this big!, i will not take a chance ..so a company of (class and mirrors) made it for me (open tank), they confirmed a test run before they take it home!! , but last night when i tried to fill it and the water arrived to the middle..i noticed the class became curved!! so i directly stopped the water tap,and empty the tank, i did call the company, they re-confirmed about the test.. in fact it cost me allot ..what to do now.. fill the tank full ?? what if ?? i will not say it!!

if you got it local...then I would simply ask them to add a couple of top braces. Again it may cost more...but you will sleep better at night not worring about a room full of water. And where are you from "manama"? It's "GLASS" not "class" but that's really just spliting hairs.

Being it is made of glass. You could return it and tell them to add more bracing. If you are worried it is the only logical thing to do, because if you dont it will bother you until you die. Considering the money you have already invested, a few more bucks wont matter.

heheh .. it is GLASS , i'm from Bahrain, manama city .. thanks to u all ..

the company will send someone to check the tank.. i'm worried about the test as they said.. i don't think the did it.. well.. what i think is to brace the top by a piece of GLASS with a square open in the middle, no joints , it will support the top, don't u think so?

If it were me. I would use two braces dividing the top into thirds. ie left side of tank 2' brace 2' brace right side of tank.

hi all ,

there are 4 triangle on each corner 5'' and in the middle, 2'' from back to front ( 2 pieces , ( get the idea ?? ) , so when i fill the tank , the 2 pieces broke because the GLASS curved in the middle, what left is the corner pieces but that won't make support for the middle of the tank

i think some simple top bracing like this should do the trick...

The tank should be very safe, especially if you look at the 65cm height, which in effective gets filled with just 60-62cm of water. You can even get rimless if you opt for 15mm glass, but for 12mm it is best to use top bracing which consist of 4 sides of bracing and a single center bracing.

My tank for comparison is 195 x 70 x 80 net and it does just well and safe enough with 12mm japan-made glass, because it has top glass bracing on 4 sides with a single center brace.
