Derimming good idea?

Is it safe to derim standard 20g long, 75g, and 120g fatboy?

Or will the tank crack?

I wouldn't do it. The rim doesn't really interfere with the scape on bigger tanks anyways.

Probably safe on the 20 long, but not so much on the 75 or 120 w/out a brace like a euro brace.

I de-rimmed my aqueon 10g. I think 20L should okay, but not for those bigger ones. I'm not really sure, but I think the taller the tank the higher the pressure.
Need someone to confirm, don't take my word.

Re: Derimming good idea?

It depends on how well the seal job and how thick the glass is. If it's 1" glass then you'd be okay as long as the seals are done well. But for most 75 and 120g, derimming isn't safe.

Any tank that has a cross brace incorporated into the top rim is a bad candidate for de-rimming. If the tank doesn't have that cross brace the plastic rim isn't adding much more strength to the top, so there should be little, if any, problem with removing the plastic rim. But, when a tank fails, the amount of water that is dumped on the floor, through the floor to the room below, and into the electric wiring under the floor, and soaking into the hardwood floor, etc. depends on the tank size. If you would be bankrupted or would think about suicide if your whole tank of water was dumped on the floor, never, ever even dream of removing the rim!

Truth.

20L can be derimmed but mine personally looks like crap. You can only do so much with Petsmart silicone jobs. As cheap as some other brands of rimless tanks are getting, I wouldn't even bother derimming. Just buy a rimless one.

Just buy a real ADA tank and forget about de-rimming a Petco tank...

It's not only about the rim on a nice tank...it's all about the clarity of the glass. When I look at my ADA tank it literally looks as if there is no glass in the way....that's how clear it is. When I had an ADA tank and a petco tank I would always ask my friends who don't know anything about tanks the following question: "which tank do you like better?" The reply was always the ADA tank with the the same reason given: "I like that one because it looks like there is no glass".

I de-rimmed a walmart 55 and the top edge was machine beveled. You never know what you'll find under the rim.

The fact that one of the tanks was rimless influenced your friends decision considering that you asked, "which one looks better"

Perhaps a question like, "which glass tank looks the clearer?"

Is best suited to get an actual opinion about the clarity of the glass.

Well, the one that did have a rim had a 10x better aquascape in it so that should compensate for the rim being there. I'm sure you have but for the ones that have not seen a real ADA tank in person it's truly night and day when comparing to a Petco tank.

Agree. Also, if you have the money...just save yourself from a possible disaster and invest in a rimless tank.

just for reference my brother got a used 55 and filled it in his garage to test it out. Well he found out once full that the center brace had broke and the pressure from the water bowed the front and rear glass enough for the brace to separate about an inch. So take it for what its worth but theres no way i would risk putting something like that with that much water in my house.
