What are peoples thoughts on 120x53cm tank over hanging on a 120x51cm cabinet? Glass thickness is 12mm....

Will be fine if you have adaquate house insurance..:D

I suggest either extend the cabinet at the back with a stip of 2"x1" wood (like answered above) or place tank on top of a 18mm plyboard sheet. Glass does not take kindly to being stressed.

That's a lot of water is it fails. I definitely wouldn't take the chance. Agree with the above re cabinet mods

Yeah, the mod is a better idea, it will go at the back so minimal decorating needed.

Interesting that my EA 900 has an overhang of about 18mm at the front with no support under the tank, this is to allow the doors to be flush. This is by design of EA.

I can't see this being any different...I guess hundreds of these have been sold and present no problems

You're talking about a different kind of overhang, there is still wood directly underneath all parts of the tank in your case and it's just the vertical support that is set back, but the cantilevered bit will still be supportive and transfer load to the vertical support

The case above the tank is hanging clear over the side with no support at one side for 2cm

This is incorrect there is definitely no support under the EA900 front edge as per the picture below...

My bad mate that's ridiculous from a brand like that if I'm brutally honest, pretty surprised and definitely not how it should be done

Must be tested for strength by EA otherwise they would not build them like this.

The bottom of the tank is constructed so it is inside the verticle sides, whether this has an impact on the stresses and strains I'm not sure.

Good thing is I've not heard of any scare stories of EA tanks bursting, let's keep the fingers crossed!

Yeh the glass being like that is worse as it doesn't have anywhere to transfer load below it so the silicon joint will take it, but the tank is correct and all tanks I've seen are built this way and it's not an issue with a proper base

I'm sure its all over engineered and will be fine but its basic design principles that you just wouldn't/shouldn't skip as it gives very little aesthetic gain, zero cost saving, and zero technical reasoning

Something to note here is that other tank manufacturers also adopt this approach Red See do it on their Reefer range of tanks.

Slightly off track but I've noticed the base of EA aquariums also have the top inset from the sides, so it's only really the 2 side pieces of glass fully taking the weight. I'm sure they're also glued but this goes against the normal advice I'd give and you'd see.

I remember a few years ago arguments about sides of an aquarium being put on top of the base (base being the whole footprint of aquarium size) or base inset from the sides like the EA Aquascaper range and sides surrounding the base.
Aquariums built the way EA do the Aquascaper gives more flexibility to the joints - something like that along with all other things.
