Not sure on the glass yet. My glass guy is going to get back to me Monday. he had to check into prices for Starfire glass.Muni;3761389; said:Looks great.
Umm... I feel kinda bad for asking but how much did a 120" piece of 3/4" glass cost?
And where in Oregon are you. I wanna see this thing when its done. I'll clean up my drool when I'm done staring I promise.
Rivermud- Thank you so much for your insight. Luckily I have not ordered that glass as my glass guy has to check into pricing for Starfire glass. I really appreciate your input. I was truly at a loss as to what glass thickness to go with given that the calculators were for rimless. My glass guy is going to get back to me with pricing for both 3/4 and 5/8. I will make the call then as to what piece to go with after a pocket book vs cracked glass analysis.Rivermud;3761877; said:Well hopefully you didn't order yet. Let me put my two cents in here and you can then make the choice for yourself. If you look at mass produced aquariums with bracing you'll find that nearly all of them fall around 2 to 2.4 on the safety factor scale. The calculators work by calculating a rimless environment. If you look at your tank with those things in mind you'll find that a piece of 5/8's glass has a 2.4 safety factor with your dimensions.
The reason glass safety factors go up with length as well as depth is because of the stress being focused on the weakest point. In the case of a rimless aquarium that will be the middle of the pane from left to right. The deeper the aquarium the greater the pressure, the longer the pane the greater the focused pressure on the weak link. this is why bracing is used. It provides a support to this weak point, essentially dividing the pressure between 2 smaller panes, the section to the left and right of the brace. The pressure is not negated however thus the safety factor calculation cannot be divided in half. Water depth is now the most important factor. At this point let me state that overkill never hurts when building an aquarium when it comes to safety. However, overkill kills the pocketbook. IMHO you can use 5/8's glass with a rimless safety rating of 2.4 and be just fine.
