Posted Tanks on floorboards
09-07-2007
17:57 by scott_91
Iv been trying to convinse my mum to let me get a bigger tank in the living room but it failed, so i thought about putting a tank in my bedroom but it will be on floorboards, so i am a bit cautious about it, im looking to put a 150 to 200 litre one in my room for south american cichlids.

Is anybody on here a builder or know anything about this sought of stuff? as far as i know the housed is about 40 years old.

I would definately place it over a supporting wall - maybe spread the weight over a solid surface & keep your fingers crossed!!

Preferably a smaller tank though....

if u can put it so that the stand runs with as many joists under it. at 1 point i had about 310 litres of water above the living room.

if you ruin your house from my advise i take no responsibility

ive got a 180litre in my bedroom , the house is about 40yrs old, but its best if you dont put all the weight on the floor, mine is also screwed to the wall to spread the weight..if you cant screw it to the wall, i wouldnt think 180litres would do any harm on just a normal stand...think of the weight of other things upstairs, such as the bath etc etc

Volume of water 200 l./43.99 gal.(52.83 US gal.)

Water weight 200 kg/440.92 lbs

Or another words 31 and a half stone.

As long as you spread the weight out it should be fine.

Just think....Would a big fat 32 stone fella stood on one leg go through your floor boards - probably not!

Just wait till your mum is admiring your fish, and then say something like

"Look mum, if i had a bigger tank it could be so much nicer...etc etc"

Works with my wife every time. LOL

however a bath is not filled 24-7 do the right thing and tell your folks to move


I have a 150 litre tank in our upstairs flat against a solid chimney stack wall......im sure it would be ok upto 150 litres.....
still respect your mums decision

good point about the bath, i dont think it would be a problem ive heard of much bigger tanks being kept without even being bolted to the wall
09-07-2007
20:42 by mwilde
How would bolting it to the wall help?

Thanks for all of your advise but im still not sure because i could just imagine what would happen if that thing went through the roof... she would literally kill me. And speaking to her shes pretty set on that it wont hold and as yet im not going to argue with her, i want to stay in her good books if im going to get a new tank.

i had a 4x2x2 on floorboards upstairs with no probs
09-07-2007
21:38 by scott_91
I wouldnt have to resort to this but the tank in my living room is 81x31x41cm so i asked if i could go slightly bigger at 101x50x41cm which gives me like another 80 litres but she said " i dont know that ones taking up enough room " thats just un-reasonable, i meen whats 20cm extra?

Well if Woz's calculations are right then it would say be two 12 stone people and a 10 stone person. If they stood on the area that the tank would be I doubt the floorboards would give in. Aslong as yu spread the weight over as many joists as you can you'll be fine.

bear in mind that your house is 40 yrs old so it'll have 5x2 joists i used that size to make a tank stand for my 7ft tank. my whole tank is held up with two of those. the inherent strength is massive. as long as you run the tank in the same direction as your floorboards and dont put it in the middle of the room (which would still be ok, imagine a cupboard full of clothes, a settee with four people in the middle of the room, would you worry about that falling in? thats about 2 ton easy, never gonna happen) id put a 6x2x2 up there without hesitation. incidentally i am a builder.

i had a n 8x2x2 in a house with floorboards and a cellar underneath had no probs i put tank across joists like others have said
09-07-2007
21:57 by scott_91
thanks, im convinsed, now i just have to make my mum agree now, which could be a difficult task.

To be honest i never doubted that it would be ok because iv got a 77x32x177cm shelving which has;

60x30x30 cm tank on the bottom
100+ Dvd's on the second shelf
40+ Xbox Games on shelf three
and a petrol rc car and loads of spare parts on the top ( which is fairly heavy )

So i bet that all of that *** weighs a fair amount when you thinks its all on a 77x32cm base. And i have a 45x30x30cm tank next to this shelving so thats quite alot of weight in a 4ft area.

One thing to check is that the joists are going in to the wall and are not supported by metal joist hangers instead. It wouldn't matter how big the joists are if they are supported with metal joist hangers as these would be the weak point.

My Dad had a colleague that made this mistake he was an IT bod at an engineering firm after numerous serious chats about what he had done he got a structural surveyor in who made it quite clear the tank should be move immediately.

Assuming the joists go into the walls make sure the load is spread evenly over the floor boards by placing a large piece of timber or an mdf board underneath so you don't have high pressure points.

Just think how much more it would hurt if someone stepped on your foot wearing stillettos as opposed to trainers you have to consider the pounds per square inch factor I would probably trst the joists but not necessarily the floor boards especially if it was a metal legged stand.

alan i think your view on joist hangers is mis informed, they have to meet building reg requirements. there isnt an issue with weight there

Pretty much as the other peeps have said.

Your water tank in the attic is around 60 -80 gallon, same joists in the attic that are in you floor boards.

So long as the air vents on the exterior of the house have not been blocked up there shouldnt be any probs.

Safe as Houses..... pardon the pun

make sure the stand legs are over a joist and not the floor board,if they dont work in put the stand on skids(pieces of wood that will spread the weight),you will no where the joist is as its where the floor boards have been nailed
