Weight Of Tank

[CrystalClear16]

Does anyone know the formula to work out how much a full 125L tank would weigh? I am considering the Roma 125 with cabinet (unless anyone has other recommendations), so would also have to consider the weight of the cabinet and its contents as well as the tank itself.

The reason I ask is because I am looking to upgrade from my 50L, but need to check my appartment's floor specs as well as convice my letting agent that a bigger tank is a good idea (any tips on how to go about this would also be appreciated!!).

Thanks in advance.

well My rio is 125 litres and I calculated the weight.

Water - 115-120KG
stand - 25kg
Tank - 25kg
substrate 10-15kg

so all in all about 185kg you must give or take because different substrates weigh different amounts etc

Thanks very much. If you don't mind me asking, is there any reason you choose a Rio over other options? Or does it just come down to price and what is on offer at the time?

185kg would only apply if it was a point load

Sorry, what do you mean a 'point load'?

It has better lighting for what I wanted it for, and I got it new for £200

Doesn't water weigh out at 1kg per litre?

Also, don't tell the letting agent! keep a broom and lump hammer to hand and when it goes through the floor quickly poke an equal sized hole into your ceiling

yes, well, near enough.

You can use the aquarium calculator at the top of the page, if you know the deminsions of the tank. Of course, this will just be the weight of the water, so you would have to add the substrate, tank itself, stand, and decorations to the weight of the water.

How unstable is your floor?! if you had 5-10 friends round for a party and they were all dancing in that room, would you be worried about them all falling through the floor?

An average man could weigh 90kg, so 10 friends would be 900kg.

Your tank is never going to weigh anymore than that, so if they do not have a problem with you having some friends round, why should they worry about the weight of the water?

Bigger worry would be making sure whatever you put it on stays 100% level, wood especially after getting damp from drips and exposed to sunlight n heavy weights can bow over time, a sinkage in the middle of your tank will cause it to crack. That is your bigger worry

900kg is temporary, not permanent like a tank, permanent load and temporary load really do differ.

I see what your saying but it's not good logic. Its not the fact that when you set up a tank that its going to just fall through the floor the likely hood of that happening is very unlikely. The problem is over time the weight of the tank can cause the floor joists that it is setting on to start to sag which is return will cause the floor to sag. When this happens it will cause the tank to start to twist and the outcome will be a side busting out or a seam giving way under the pressure. Here is a link that will help you.

Getting your tank 100% level can be impossible is some cases using wood shims can help.

900kg of people wouldnt all be on one or two joists would they, whereas, the mentioned 125litre is more than likely an 80cm tank, which cannot spread its weight over more than 2 joists.

I believe however, that the joists with the weight of the tank as described by truck will be more than fine, i think you would have to be pushing approx 150-200kg on each joist for problems to arrise.

My Rio is over 2 joists upstairs so I see no problem too
