My 75 gallon derimming project.

Right? Speak up!!

I think they use the plastic rims around the tank to actually fabricate the tank faster.
Some silicone on the bottom rim, place the bottom plate on it, some silicone on the top rim, place left and right side in, and then the front and back. Close the seams with silicone and done! They probably don't need clamps to put the tank together. As it said on the sticker on the tank "made by (person)" I don't think I can put a 75 gal together by myself without wasting hours of time. Those tanks have to been made fast due to make fast money...

Seems like a reasonable idea.

I'm derimming a 125G (6 foot long) tank shortly, but certainly plan to brace it on the sides and center. I'm really interested to see how this 75G turns out. Rimless is just way more elegant.

I found this quote which supports your experiment.

The trim (which is generally plastic) offers LITTLE support other than providing a “cushion” between the bottom glass and stand and as well a “convenient” way to place the lid, lights, etc., on top. Of coarse the trim does certainly add to the attractiveness(mg: i like that part ), but as someone that has worked with high end aquarium manufacturers and built/repaired many myself, I can tell the reader here from an experience that the trim offers little in support and if it is necessary for support, you have a dangerously poorly built aquarium!
As well, I have removed trim from many tanks (including large ones) and filled them with water with no difference other than the unattractive aspect.

I have a 120 that has always been rimless. It's 1/2" glass though, so should be good and strong....I hope!

One thing I failed to consider in going to a rimless is that if you want to go with a glass top , a rimless tank has no lip to support it. :\

You can always get the clips from someone with an ADA tank. Most people don't use theirs. Just post a wanted thread in the SnS.

Did the tank burst yet?

Any pics of the tank set up, with no rim, plants and fish? We are all holding our breath, you know.

I like mistergreen's signature. Ha ha! (Post #48)

I don't see why this tank wouldn't hold up to 75g of water without rims. Wouldn't the aquarium split in the corners if it was built poorly regardless of a rim or not?
I know my AGA 29 Gallon has alot of gap between the rim and the glass all the way around so it can't really be holding anything. Plus the pressure from that much water would snap the cheap molded plastic like a twig if the aquarium decided to pop.

of course you know what they say about opinions..

lol

Its been sitting outside filled with water to the rim from the rain and all green from the pollen. And yes, its still holding water, I think its 100% trust-able
Like I told a little bit earlier, I will first go to Europe for 2 months and then I will set it up in my new house.

That is fascinating! If I decide to revamp my 65 gallon riparium, which does have a center brace, I may remove the top rim. I think I would put glass triangle braces in the corners though just for extra safety.

[redfishsc]

I'd personally still want to put at least a 1/4" thick center brace about 3" wide (glass) on anything that comes from the factory with a center brace. Somewhat annoying but can be done nicely.

Yes, I will do the triangles to in the near future, when I have some more time.

And yes, I will do a glass center brace just to be sure

Came home yesterday from my 2 months trip in Europe, when I left, the tank was filled up with water from the rain, Today, the tank is still full and is still in top shape. I had a 75 gal full with greenwater with mosquito larves and dafia. My fish loved a couple of scoops of that live food after 2 months only flakes.

I decided to make an aluminum rim and center brace. I don't know if that tank still can be trusted without braces if I drill 5 holes in the back.
