at least 510 kg the water will weigh roughly. add more for rocks decorations, weight of glass etc. then add more for stand/gravel etc
ah im a bit rough today vaff, felt like chit this morning though terrible stomach pains stiff dizzy sick the works!
was spraying weed poison yesterday so freaked out that id got some in my mouth or something, but feeling much better now after a walk!
had a big swap round of the tanks yesterday too, OH set up another one ( a crayfish tank) its very pretty but i now have no room in my kitchen![]()
i always take 1kg for every litre of water. so im guessing that weight will be accurate + or minus a bit (less water if theres more substrate deco etc, but then they may weigh a bit more etc)
i take it its not going on your bottom floor then, its going upstairs?
what are your floors made from chick? that is a deciding factor, if its wooden beams you have to find the support beams and stuff (involves getting plans of your house and all that carp)
510kg i think isnt so much, its like having 6 or 7 hefty men standing on your floor!
our big'un is around 600kg (without the stand) and is fine up here on the third floor![]()
Theres no easy answer and most people on here won't commit themselves unless a structural engineer or someone in the know has had a look. If you know where the support beams are, putting them between those helps spread the weight about.
If you've got any mates in the building trade, may be worth asking their advice.
Did you say you've already got a 4ft tank there already? And the new tanks a similar size?
It's my understanding that 1 US gallon weighs roughly 10lbs. Not sure how much that will help you british folks though, lol.
