    Hi Guys ! ;D

    Im hoping to get some expert assistance / advice here... im considering finally setting my 6ft up in the next few months, but I have a real concern about its weight... Are there any structural engineers or similar out there who could help me determine whether it would be safe to set up ? Our predicament is as follows:

    1. We RENTING a flat on the THIRD floor of a complex...
    2. Tank specs: Length = 1.8m x Width = 0.5m x Height = water level of about 0.6m.
    3. Sump is quite small and equates to only about 100L
    4. In view of points two and three above ( and assuming my calculations are correct ) total system volume will be about 540L ?
    5. Now the tank itself is FLIPPIN heavy... can anyone give me an indication of the glass mass ? 10mm glass all around with quite a bit of bracing, and two 6mm sliders of +/- 30cm x 90cm.
    6. Then further considerations are the cabinet, décor and equipment etc etc etc.... AKA " the odds and ends " ;D

    Our current tank is a 5ft with a volume of about 300L, and we have also had the abovementioned sump as well as a small hex tank all set up next to each other / in the area where the new tank will be placed with no ill effects.... And for good measure: I weigh about 100kg ( and regularly work in the current tank / stand near to it ) which in total is very close to the system volume of the new 6ft.... so will it be ok and how can I make SURE ? Is there a way to calculate the mass which the concrete slab can safely sustain by measuring its thickness or something ? I personally think it will be fine "“ but I just want to make sure that it will be fine long term.... ?

    Best find some structural engineers to quiz. They will want to know more information:

    1. where is the tank placed relative to the support for the floor?
    2. of what is the concrete composed and how many layers?

    In principle, if the room was filled with people the floor should still stand. How many people can fit into the room? Assume each person is average mass (70 kg) and guess from there. If each flat is identical, position the tank as close to the supporting walls as possible (not that I think this matters in the least).

    You may be able to get the name of the architect who designed the building. He should have the information you need.

    Hi Tyrone - Thanks for the quick reply. ;)

    IF a structural engineer or someone similarly qualified were to per-chance read this thread let me try and answer your points:

    1. Tank is indeed placed up against the wall which forms one of the main vertical ' pillars ' of the building
    2. Im afraid I havent the foggiest of what the concrete is composed of... :(

    The builing is fairly old and thus perceived to be quite ' solid '... it was built in 1974.. and as for the ' total number of people test ' I know that in the past we have had a get together with ( conservatively ) 15 - 20 people in the living room where the tank will be placed. So i must admit i think it will be fine... just hoping to confirm that it will be fine long term...

    ???

    Yip... so I would work on an estimate of about a ton taking into account water volume, tank weight ( Glass + cabinet and accesories ) as well as people standing near the tank to view or work in it etc... ?

    You should try and find the beams of your floor, if possible, and place the stand on them, but for that you'ii need the drawings. Also how many legs does the stand have? say you have six in total, two on each side and two in the middle, the weight will be more distributed across the floor, so the load won't be so much on you point, cause remember that a certain point can only handle so much weight. So you can check on your drawings it should say or you'd be able to calculate how much weight your floor can handle.

    I'm no expert but i did do mechanical engineering for a while, so I know the basics, but just to make sure if i was you i'll check with a pro.
