my guess is safety factor is an arbitrary rating of the overall stress on the tank based on the tanks dimensions and water weight. They didnt give any units of measurement or a scale? kinda useless number without some meaning
I get what you're saying. a Factor of 1 would mean that you are at the theoretical strength limit of that particular thickness, while a factor of 4 would mean you are only putting 25% load on the glass.
I did some clean up on the tank this morning and then ran some errands. Ran by petsmart and took a look at some other 55glass, and I noticed how much beefier 9mm glass looks compared to 6mm. I realize it's only a 50% increase, but it's much more impressive to the eye.
While everything I've been told here says that the tank *should* work, I think I'm going to just resell the tank and hold the money till I can find a 75 or 90 to upgrade the current 55 from. It is a nice tank and I may be able to get more than I paid for it which is always nice, but I'm just not sure I trust it being that it would go into my carpeted home office. I do work from home and if this tank were to fail it would be a catastrophe, nevermind the loss of fish.
I guess it's always better to sleep on an idea than jump in both feet first.
