Stocking Ideas For An 8 X 2 X 2...

Sigh :no: , yet another flamer who attacks someone for just having a smaller tank as they dont have room for a larger. I can assure you, that the frame WOULD be further strengthened if there were cross bars on the base: Ask those guys they will tell you: that is simple logic: Force is pressure per unit area: Decrease your area and decrease the force on each seperate area. Remember for an 8 foot tank we are talking: Thats 900 Kg of Water weight alone nominally: Plus the weight of the tank liably ~100-150kg Plus substrate: lets say 1.5 inches deep Thats Approximately 50kg+ Add decorations....

This is a Tonne of weight: Have a look at the chassis of your car(unless you drive an SUV), This is the equivalent weight you are supporting: wouldnt you rather for the petty cost of 2 further pieces have added reliability: Remember if force occurs for a long period of time Ductile deformation can occur. Either way, thats your design, your happy with it, its good for you: id just wonder about possibly having cross supports to support your sump system to keep it off the floor? Or do you already have a plan for this otherwise wouldnt there be potential for thermal contrast cracking?

My main comment was directed between your design and Adam: Adam take a leaf from Ganja on the bracing accross the top: particularly when talking large tanks its much safer.

Out of further interest what type of steel(id assume its a hybrid but not sure) are you using Ganjaman? this might give paula a further idea. Also just for return of serves sake: Ask your builder what is the strongest supporting shape. Btw whyd you get an architect to look at a fish tank stand? a Welder would know well enough.

Either way dont flame when you personally dont have the know how and rather rely on builders and tradies to do the work for you.
 
This is turning out fun ! , i_ganjaman my guess would be your frame would take about 4-5 ton easy the only way it would need more braceing is if you fitted a wave pump.

I am going to change the design a bit by adding an extra 2 braces front to back on the top and bottom also the front top crossmember to 2x4 or 2x6.

Not sure of the steel spec im using prob just ERW unless i can get 316/304

The inside of the frame is also going to be linned as well the sump will be acrylic, Did i mention im an engineer
 
Xebadir,you clearly had your guns out at my design by addressing me at the start of your pathetic rant.Try putting Adam or Paula, If you want to enrich their minds.Dont know why i'm doing this but you have rubbed me up the wrong way. SO
1.My friend is an architect to busy with his own work, most of them are self-employed,so he just agreed to look over the design on paper.(no money spent)
2.you got to be a fool if you dont use contacts that can help you(I used to work where the stand was built and they had no problems with the design).
3.Just room to fit a 20 gallon tank....Do you live in a Cardboard box or perhaps your still living with mammy and mammy wont let you have a bigger tank
4.I think nobody is interested in your pathetic whimpers.
you clearly dont know what your talking about.
5. bye bye

Well the only reason I even bothered to return fire is my offense at being mocked just because in my current Apartment(Yes I am a student, and dont have the money to purchase a larger house at this time, my apartment is under restriction on fishtanks, with 2ft being the max allowable on my floor. In time i shall but I have a lady to attend to before this point). Im not saying there is anything wrong with using contacts, I just believe that half the fun of getting a new setup is designing it and working on it yourself. :good: . I do look forward to seeing your tank. As for point 4. this is uncalled for and reflects your age, totally immature and material, not in the least pathetic. I believe in overbuilding things: better safe than sorry im sure youd agree.

Id be interested for you to start acting mature and stop mocking me, and enlighten paula to which steel(id assume from the robust construction you used a open box steel bar) you used, the costs involved in designing such a stand. I also made the enquiry for Paula's sake about how you plan to support your sump: whether you plan to floor base, or lift it off the ground in anyway. But considering you are too busy Flaming me for actually trying to help you bestow your infinite wisdom, i really dont know why I bother. I wish you much success in your planning and execution Paula, and I hope one day that I will have the space to hold such a tank.
 
My apologies, really i hadnt re read that post: I should have posts made in the early morning really are a mistake. As for adopting that tone, dont be a rude person: people make mistakes: correct them dont flame, acting like that is the best way to distance people from the help site that is these forums. Still Further cross bracing would be useful for keeping the sump off the ground? or arent you going to answer the questions because of your arrogance.

Ohh and Jumpman would you flirt with a 900kg grouper? or dont you think it would bite your head off.
 
first i like to offer my appologies to you.
there are no bottom braces because the extra few inches will help me maintain the sump,And change equipment as and when of breakdowns like i said in previous posts you really need to think about all aspects.So what are you studying?out of interest.........
 
Apology accepted, thank you for acting mature about this. Ahhh ok intriguing.

As for what im studying: Meteorology with a Maths Minor. Supercellular Tornadics and tropical interaction are my interest fields.

Now thats enough hijacking for me :blush: lets get back to offering Paula the advice.

Paula:
Have you though of purchasing an RO unit for purifying water for the tank if you dont already have one?

Do you have some sort of python system for filling a tank of this size?

What sort of substrate are you thinking for fronts?

What sort of Pleco(Id assume this is what your looking with such great size or you could go for a group of Sydont Eureptus or maybe something more exotic B) )
 
Ok then ,Who can answear this a quick way to find out who know what

Q. whats the psi on each of the upright legs if the tank weighs 1500kg ?
 
Difficult question: A couple of assumptions(after all you are an engineer)
We are assuming that the weight of the tank is evenly distributed.
We are assuming that the weight of the top part of the frames effect on the supports is neglible.
We are assuming that the surface on which the stand is placed is level
We are assuming that the area of the body steel square pipe is 1 inch squared.
Assuming the system is yours with 6 supports vertical
Hence logically the PSI of the system is:
1500x~2.2
=3300pounds
over the area of 1 inch squared, for six different supports:
550 Psi

Note that ive prolly screwed this up...its 1:32 am lol.
 
i_ganjaman, :good: thanks for the info on the sump! :)

Hadn't considered an RO unit, as I didn't think it was necessary for most set ups (apologies if I have this wrong, I'm still researching ;) ). If it's a good idea, then definitely. Can see how it would be necessary if pumping water straight into the tank.

I was wondering though, when doing fairly large water changes, how that much cold water would harm the fish, our water is ice cold in winter :crazy: I was thinking of pumping water into a holding tank to allow it to lose the chlorine, and have a heater in that tank.. then pump nice warm water into the aquarium.. dumb idea? :blink:

Haven't got a pumping system, but I like the looks of it! Filling a 75G with buckets is doable but I think this size would be too much :D although I'm not keen on just pumping the water out of the aquarium and down the sink, I'd rather send it out the door and onto the garden.

We're reading up on making a rocky background (will try a smaller version first though!), otherwise fairly fine gravel and sand substrate, with rocky outcrops and some caves - smooth rockwork as I've read the fronts can get spooked and bump into things.

Ooooh... pleco pleco... still looking into that, and have a while yet to work on a wish list :D have just joined the local aquarium society and will see what is being bred locally as well as what's at the lfs. I like the idea of a school of Synodontis (or as I decribe them to my OH as 'swimmy catfish') but I really like the plecos.. also depends on what's available here (Canberra).
