So today I scored some awesome tanks from a local club member here. 2 X 60 gallon breeder tanks that were custom built by another local club member here a year ago. The tanks seem to be built, well, like a tank. Very structurally sound, holds water well. However... it was built using a mitered wooden rim... From a strictly vertical support view, this seems to have been done very very well, meaning that the bottom is well supported and I will be leaving the bottom trim on. However, right now, being that its a mitered wood trim (4 pieces of wood, glued at the joints) I'm not sure how I feel about the structural integrity of the tank from a bowing safety rating.
The tanks dimensions are 36" long X 19" Wide X 20" high
Safety calcs that I have used show that this tank without bracing has a safety rating of about 4.4-5 . While this is well over the industry standard for a braced tank. It is definitely not at the 7.6 mark used for rimless tanks.
I plan on filling the tank and measuring bowing tomorrow. But depending on how much it bows I may end up bracing the corners? Like this tank
Basically 6"X6" right triangle on each corner? I think that would look better than eurobracing and I could just leave the top of the aquarium rimless without the mitered rim. I do plan on drilling for an internal/external overflow like the user, "crazymittens" has here on TPT. I would leave the bottom rim braced.
What do you guys think? Can I just do the corners? Or should I euro brace it?
I feel like with the bottom trim and corner bracing I shouldn't have a problem? I have plenty of spare glass, I may try corner bracing and see the bow/deflection and see what happens.
The glass is 3/8" thick, which falls right in between 9 and 10 mm
