I'm going to go with no, unless you want to Euro-brace it. I'm curious, how thick is the glass and whats the dimensions?
De-rimming question
okay so i have seen many people de-rim their tanks my question is i have a 75 that is that real thick glass that has no center brace. can i de rim it and completely fill it up without any problems?

standard 75 demensions and the glass is about 1/2 inch thick i think
If its 1/2" you may be ok, 3/8ths would be sketchy without bracing it imo. Maybe someone else here has successfully done this though?
I've heard de-rimming anything above 10 gallons is a bad idea. I personally wouldn't try it with anything bigger than 5.5 gallons.
Is it worth 75 gallons of water on the floor to risk it?

I've only seen 10g tanks de-rimmed and those do just fine. I would't wanna risk something larger.
I derimmmed a 10 gal and I've seen a few here do the same.
I however noted that there is bowing in the middle part of the front and back of the tank. I had to make an acrylic brace to prevent bowing out when I fill it with water.
Doing it on a lrger tank is definitely a no for me but there are a few who have done it on a 20 gal long.

IDK, from what I've heard, the rim does very little if there is no central brace....If yours HAS no central brace...
Perhaps fill it in your garage and check how much bowing there is...then remove rim and do the same. if it works out, clean up the edge, if not, reapply rim.

That's what I was thinking this is an oks tank do the glass is rather thick.it took 2 and alot of man power to lift it. I may do it in the spring but I may not
Hey there,
There is a sticky on a guy that built a 75G All-glass, rimless with no bracing w/ 1/2" plate glass. I don't see a problem with it, but you could always check a safety factor for it if you were that worried about it.

l agree, I rather have 75g in garage or outside house then inside.IDK, from what I've heard, the rim does very little if there is no central brace....If yours HAS no central brace...

After de-rimming the top of my 20L, I really feel that the rim doesn't do much. Many people say the reason for it is merely to speed up the assembly process. Others say it is to cover up the sloppy silicone work. Others say it makes it much easier to make standard accessories (lights, plastic canopy, glass tops, etc). Lasty, some claim it just adds an extra level of safety as pretty much all off the shelf tanks (that don't have a center brace) meet the specs of DIY calculators. I don't know enough about it to say it's going to be safe but that rim does not seem to stop any bowing on or off the tank.
This is obviously "do at your own risk" and to me, it would be that the tank is so big it needs a rim for structural reasons, it's just that 10 gallons on the floor is bad, 75 is a flood. 10 gallons used to be the absolute max, now it seems that 20L is. I have seen a couple 29 gallons de-rimmed that have been up for years too. Many have said they think the tank size will continue to increase in terms of what people feel is "safe", it's just that someone has to actually do it, have it for years, and not have issues, then others have to do the same and verify.
I know my post is all speculation but I think the only way to really know is to try. Obviously verify using online calculators but even then, the silicone quality greatly varies from tank to tank with AGA tanks. That further makes me think it isn't that important but that's me. On the flip side, I think once you go over a 20L, the rim isn't intrusive enough to risk. The only reason I derimmed the top of my 20L is that the rims are huge compared to the viewing area as it uses the same size as the 29. Not to say a large tank won't look nice rimless, I am just saying I personally wouldn't risk it.
I know my post is only opinion and my gut feeling is its fine, the logic in me says it isn't worth the chance of failure, but I would like someone else to try:icon_twis:biggrin:
