Hello everyone,
I'm planning out my next upgrade and I'm wondering if what I have planned will hold up long term. Basically, I'm using an existing 180gal (72"x18"x30") custom tank and I'll be reworking it into different dimensions. The reason for doing this is the dimensions of the tank itself. I thought it was a standard 180gal (72"x24"x24") which is what I really wanted and is my dream tank until I move into a larger house, but upon arriving to pick the tank up, it was not a standard 180gal. Ultimately the seller was only asking $180 for tank and it was scratch free, so I couldn't really pass it up just because it wasn't quite the size I had wanted. However, I really don't like the idea of a tall and narrow tank, as 30" tall means I'll be putting on a snorkel and mask anytime I need to work on the bottom of the tank. Not to mention that 30 inches tall and only 18 inches deep means, not a whole lot of room for corals and a nice aquascape. There are also three fairly large holes on the back of the tank that I would need to either plug (which will not look very nice) or make into a closed loop setup and I'm not really sold on that idea yet. So its been sitting in my garage staring at me until I finish the upstairs remodel on my house, which I'm getting really close to being done with, Yay! :D

Then one day I came across a build thread here on R2R and it inspired me. So I did some math and I figured out that I can flip some of the panels around and with a few cuts I can do a shallow but wide build. The dimensions I'm thinking are 60"x30"x18" or 72"x30"x18". The reason I'm considering cutting off a foot from the length is that the overall cost for setup is reduced by quite a bit. I could get away with one less light fixture, I could go with a smaller skimmer, and I would need smaller/fewer wavemakers. Seeing as how I'm on a fairly tight budget, this would help me get the tank up and running much sooner which is ideal. On the flip side though, I really do want some larger tangs, like a powder brown and Achilles, so the six foot option would be my preference if I could find the budget for it. Now cutting wise, I'd actually be able to cut out the existing drilled holes in the back panel.

So my question here, the existing tank is 3/4" glass with an aluminum rim and bracing top and bottom of the aquarium. If I changed the dimensions could I get away with doing rimless? Or would I need to brace it with a euro brace or something? I'm not opposed to doing this, but I would have to end up buying extra glass from a local shop then.

I should also note, I work for a quartz, granite, and marble countertop company, and believe it or not, glass isn't that different to work with compared to some of the materials we work with. So for cutting I can lay the pieces down on the water jet table and cut them down that way. Also, all polishing pads for stone work on glass, so I'd be able to polish out the glass edges easily.
 
You sure have a great skillset!

JMO..
But, I would run one wider sheet of glass splitting your 60" length, tied into the front and back of your top side 30" depth, then euro brace the rest of your top side (4-sides) so that is tied to your middle glass bracing.

Again, JMO

FWIW:
My regular (black) Achiices tang, is the only fish that will eat from my hands... :D

Interesting thought. I'm just struggling with the fact that its 3/4" thick glass and not 1/2". If it were 1/2" I'd 100% need bracing. But with 3/4" I feel that it should be structurally strong enough to go rimless. Waterbox aquariums makes a similar sized aquarium out of 3/4" glass in rimless fashion. But I'm still curious as to what others think due to the 30" wide.

I really would like to stay 72" in length, and everyone I talk to with tangs, just makes me want them more. lol I may just deal with the extra cost and take a little bit longer to set it up. I think in the end, this tank will come with me to my next home when we move sometime down the road.

Let me call in another member that I fully trust.

Just be patient with his response time,.. Frame... :p

@Brew12

Would you run euro bracing, or with trimming it down to 18" tall with 3/4" glass, would it be safe not to euro brace?

Thanks!
 
So....I'm reading this, and my only concern, is tempering. Have you checked if the glass is tempered? I don't know if that will factor into cutting the glass itself, but I remember that you can't drill tempered glass tanks (silly 55 gallons...).

Great question! I bought the tank from a guy who actually started one of the local aquarium shops. He told me none of it is tempered. I need to confirm it yet for my own eyes yet, but I have no reason to not trust his word. After all, he did build the tank.

Fortunately, the width of the tank doesn’t impact if eurobracing is required. It’s all about height and length.
3/4” should be fine for 72”x18” imo. Just ensure a very good job of caulking is done.

Thank you for your input @Brew12, that's wonderful news for me! Though that doesn't help me decide on a length yet. Lol I was silently hoping 72" would need euro brace so that I would have more reason to go 60". Oh well, as they say, first world problems.

I know there is some high strength silicone ment for larger tanks with higher pressure ratings out there. I plan on using that silicone and taking my time and being very thorough with assembly.
 
I have a three-quarter inch glass tank very very strong I would think that you can get away without it as mine is a six-foot-long 2-foot wide 2 foot tall and it is rimless just make sure that when you put it together after doing what you doing you at everything fully cure your Silicone is going to have to be spot-on going to have to be right and tight maybe try putting some water in it before you put it up on a standard anywhere else and let it sit for a couple of days just to be on the safe side throwa power head or 2 in there and see what happens.
