My 75 gallon derimming project.

wow. That's awesome. I hope it holds.

Nice to see the experiement! And I agree, nobody does bigger tanks because they're scared. Heck, I'd be scared to do it. Hope it works out for you!

Keep us updated on it? It would be funny find out that the frame is just for liability issues.

With that little bowing out, I think I would make 4 glass triangles about 2 inches on the side going against the end glass, and about 6 inches on the side going to the front/back glass. Then glue them in and I don't think there is any chance of problems. For safety I would knock off about 1/4 inch of the sharp point on the triangles, and break all of the corners so they aren't sharp. The corner braces should virtually eliminate the bowing.

I'm assuming that the tank won't come apart in a week of testing. To "proof" test it, push out on the front/back glasses with about a 1 pound push. That should increase the load on the glass by about 50%.

I think i will go with the triangles and the other piece.

I pulled on the glass really hard and no problem at all.
I'm almost 100% sure it will hold.

thats awesome! and looks great! ill probably take the bottom rim off my 20 long. im just worried about what will happen if the stand is warped in the middle a bit. or at least uneven

This could be a new trend in DIY.

I have a question is your 75 gallon tank fine because it's older and the glass is thicker? would this work on a brand new 75 gallon tank?

[macclellan]

That looks. Like a very large glass schrapnel grenade - you've got cajones!

[EntoCraig]

I want to see how you brace it. If it turns out to be sturdy I may take a shot at a 50.

Your my hero Nalu! LoL. I agree you got some Cojones homie! I think that, all though this is a pretty cool break through in DIY Rimless, I don't think any one should ever keep a DIYed tank of this size in the home. This should be for a basement with a drain and/or a garage. 1 week might go by and all is well. After a month or 2, it might be a different story. I was in a LFS yesterday and I found a Deep Blue Aquarium 75 Gallon for 100, lol I was tempted. lol.

Im not a hero, just someone who likes to experiment lol, thanks tough!
Yeah, I don't want to put the tank like that in my living room with hard wood floors, certainly not without the glass braces. In 3 months I move into my new house (after a 2 month trip to me and my wifes hometowns in Europe)
and then I will finish the tank and place it in my garage, for further tests.
Maybe If the tank is still fine after a year (maybe2 years) I will make one like this and put it in my living room. Would be a beautiful cheap tank

If you watch craigslist, you can find tanks for free to very low prices. I bought mine for $50 and was 5 years old.

It's better to be safe than sorry when it comes to glass and ~600 lbs of water. It may hold for a few days or even weeks in your test but it's in your hands ultimately. Have house insurance ready.

You can also obsess over the possibility of any tank breaking when it is in the living room on a hardwood floor. In reality that tank is either designed with sufficient safety factor while rimless, so the rim is not a structural part, or it isn't. We should be able to make that determination independently. Right? Speak up!!
