I need to make a stand for my daughters fish tank (Christmas present). It will weigh approx 30kg, + the weight of the tank, so c35kg.

It needs to have a top size of in the region of 2' x 1', will be freestanding, with its back to the wall, approx 2' + plinth high.

My plan was to use 18mm oak veneered mdf, and 5mm dominos. It may have a face frame to finish it off. This is the first time I have done anything like this and I could use some advice.

The floor is pretty level, so I was planning on using some cls to build a base frame, fixed to the floor and perfectly leveled as necessary. This will later be covered with a front plinth, and the returns scribed to the skirting. My wife has plans for some cubed structured in the room, so I was going to start this theme on this first cabiniet, and it will have a couple of wicker baskets in the bottom for storage. The size of the cubes is dictated by the baskets available- they are roughly 12" in all dimensions.

Would something like my image be strong enough to support the tank without a back? If not, would it with a back? I would prefer it without the back to simplify construction, and to lighten it up a bit.

On face frames, I assume that I would use something like a 40mm section all round- what would happen at the pieces that are single thickness mdf- I assume that the outside would be flush and the inside overhangs?

The alternative would be to have 2 vertical pieces, so flip the image 90 degrees, or 4 separate cubes joined to each other- any better or worse?

Marcros, there are very good reasons why you rarely see free-standing bookcases, wardrobes and chests without a back!
 
This is true. I could fix it to the wall with some brackets as a compromise?

The back isn't a huge issue really, it is only a matter of running a rebate on the outside pieces, and cutting any middle pieces slightly shallower. In honesty, I suspected that it would need it, but was still unsure about the strength of the structure, not having done much with mdf before.
 
30kg is 30 litres of water is that all the tank holds?

With out a back a knock from the side will make it collapse, I did a tall thin one with two 75mm strips up each side to stop it racking.

Yes, it is only a 30L job. She only wants to see a couple of small fish swimming around, so we thought that we would start with a small one. If we like it, then we can get a larger one in time. The tank itself is acrylic, so not a great deal of additional weight. http://www.biorb.co.uk/products/product ... rb-flow-30

I think I will just go for the back on it then.

Mailee made a fish tank stand, I can't remember if it was free standing, may be worth checking out his posts.

Thank you. I remember that one, but it was more of a cabinet, whereas mine is more of a short bookcase/stand.
 
Marcross, if you've done nothing yet think about a larger tank. You won't have half the problems with a larger tank that you are likely to have with a small one.
You'd be wise to make the unit 100mm or so deeper than the tank so ballast units, pumps, food etc. can be hidden around the back.
 
sadly we have already bought the tank Phil. The plan isnt to stock it to its maximum density or push its limits in any way, so hopefully it will be ok. Would live plants assist in any way or are they better avoided. I always think they look better!

I note your point about the depth of the stand, and will add on that extra 100mm or so.
 
Live plants help (I think) with water quality, but they can be difficult to grow in a new tank. Some are a lot easier than others though, and some fish will destroy them - you shouldn't have that problem with a small tank, it's capacity governs what you will keep.
 
live plants are always a bonus

and gives the smaller fish somewhere to hide
a 30l will only need a pedestal if that helps with design

with your design if the cross is fixed left right & up down it should be stable without a back imho
 
it seems that ms paint is no substitute for sketchup, but my initial idea was as below. The red lines are dominos.

You probably need only 6mm ply for the back to stop it racking, and then you can get some mirror glass to glue to the inside of the back panel - same number of fish, but twice the fun!!! :lol: :lol:
 
Sorry just looked at this again

I would go with full height uprights
the centre "shelves" would then stop some of the racking

I also see a plinth
hide some 2 x somethings underneath as support ..rather than just a outside skirt

I have a neigbour with a 4 foot tank on a sideboard with plinth
there was nothing under \ inside the plinth and it collapse one end
We had to jack the end (tank still full of water) to get some timbers behind the plinth

EDIT

I just see that u was going with CLS...I must learn to read entire description :oops:
 
hi I would go for back defo you could paint same colour as wall also I always put tank polystyrene under tank do'nt need to be to thick 15mm helps in case you get any thing under it stops tanks cracking when filled, are you going to make a hood to grow live plants you will need the right lighting certain lights make fish look better to #-o
pip
 
pip. I am going to have a look at what we have with the tank when I get a minute, and will drop you a message with some questions on about lighting, plants, fish and polystyrene! Thanks
 
I have been keeping fish for over 20 yrs so maybe able to assist as well

my latest is 3500 litres in the back garden :D
