Aquarium too heavy for drawers?

What storey? And if ground is there a sub-void or basement below i.e is it a suspended floor?

That chipboard is hopefully at least OSB and not chipboard. If it gets it replaced. Some muppet put true chipboard in our place and it is going mushy. Not cool.

It is a ground floor and my belief is that it is not a suspended floor. I drilled a hole to look and there is a layer of cheap yellow-type insulation and then what sounds like brick/concrete around 4 inches from the floorboard.

built in 2004 you say? any building regs or planning application on the council website? if you're the owner you can write and request copies. that will probably tell you what is there if the developer won't provide you with copies. Scotland is different from England but you still need a building warrant and it should cover much of the same info. provided the insulation is rigid (not compressible) enough and there's a decent thickness of concrete (or a reinforced concrete slab) I imagine you'll be ok. timber bearing onto a rigid substrate is generally ok. if you own you can take a view. if you're renting be more careful. only way to say for certain is try and find out exactly what's there however.

Don't forget to put some high denisty rubber/foam directly under the aquarium to prevent vibration, a mate didnt bother which lead to a cracked tank (6'x4'x2.5' iirc) a very soggy living room and a late night trip to to the local Aquarium shop to save his silver dollars. Luckily we were all watching a film in the living room at the time, The Matrix with his DTS sound system cranked up

beware drilling through into a damp-proof membrane. (often a form of either painted-on bitumen style or more common these days a heavy duty polythene.) They can either be above or below the main slab. Seal it back up if you have drilled into it. Just make sure what you use will adhere properly and set to be fully water resistant - ie impermeable to moisture and vapour.
