De-Rimming a 40 Breeder

Would you do it? I mean, most ppl say as long as the tank doesn't have a center brace it should be ok. It doesn't have one but it still looks a little big to be tampering with. Additionally, it is for a saltwater setup I am doing so the glass itself may be somewhat weaken by the 3 1inch holes I'm drilling in it for bulkheads. Its alot more water than I would ever want on my floor but now that I have already purchased the tank all I can think about is ripping that ugly black trim off the top.

I wouldn't derim anything over 10 or 20 gallons... If it has a rim, it's likely there for a reason.

I'm not sure about removing the entire top rim, but you could remove the front piece of the top rim like Shrimpo did in this shot of his 40 breeder riparium:

tuffgong - from a structural standpoint, what purpose do you feel a a partial rim serves? It would seem that on a rim that runs the full circumference of a tank any benefit derived must be lost when u take out a section.

It is nice to see someone has done it successfully but the pressures imposed on the glass/seams is alot different in a full tank vs half.

Since the only real investments I have made so far on the tank are this MT itself and the sump I constructed I have been looking into rimless tanks. However, I can't come close to the $40 I spent on the current tank for a quality rimless one (thank you petco and your $/gallon sale!).

A plastic rim adds very little strength to the glass. Those rims bend easily compared to the stiffness of glass. When there is a cross brace that is a different story. But, if the holes you put in the glass are near the top of the glass I think that would be the "straw that breaks the camel's back".

Is drilling a rimless tank even advisable (assuming non-tempered glass of course)? Like an ADA or Mr Aqua? They typically have slightly thicker glass/volume dont they?

I believe Shrimpo only removed the front rim for peace of mind. Many many users on TPT say you can't de-rim a tank larger than 20g safely so I think removing the front piece only was a compromise.

I have a de-rimmed 20g long (top rim only) The front and rear glass panels bow out ever so slightly. About 1/16 - 1/8". I'm not sure about the drilling part, but if you are going to do it I would fill it up and let it sit outside for a couple weeks to make sure it doesn't leak all over your floor.

Good luck and let us know how you fare!
