All it would take, is to have built one corner of the stand an 1/8" higher and the kitty corner a 1/16" of an inch lower and now you have a 3/16" difference. Add in the fact that it was 1/2" glass, it is quite possible that the tank could twist when settling as it is filled, causing it to crack. Does it take more than 3/16" to accomplish this? Not sure as I am not an engineer. All I can say is that if you put a rigid frame on a stand with that type of issue, it would rock...A 400 gallon tank, filled with water would distort as the silicone will allow a certain amount of distortion before failing.
In one sense I agree with the fella wanting to see pics of the stand, but the other guy is also right, as the pics would not show anything since the tank is already damaged/distorted, if the stand was in fact the issue. The only way to do it, is to measure each corners height.
I also agree that we should not just bash companies. Peoples livelihoods are at stake, and as a business owner, I know what it takes to build a company and it takes nothing to destroy a reputation. Not saying he is right or wrong. I just think all the facts need to be had, and this forum could probably never attain this.
I am not sure how topics like this, make some people think it is ok to bash anothers opinion or accuse him of things. I for one come on here because it is suppose to be a "COMMUNITY" of like minded people. People who are looking to become informed. To me that is created by discussion. Discussions that may have opinions that you think are "stupid", "ignorant" or whatever...Seems simpler to be the bigger man and just state your rebuttal/opinion in a fashion that may make the other think about his, maybe even making him change it, rather than bashing them, which will almost always get the same response, which just makes us all look like children.
Sorry, just wanted to add my opinion.
