I am planning on a 350 gallon tank. Which will be 108 x 30 x 30 or in feet, 9' x 2.5' x 2.5' The tank will actually be an Amazon tank that will contain fish that only come from the Amazon area of South America. As of yet, I haven't decided exactly which area to concentrate on.

Watch this space, it might take a while but hopefully it will come to fruition within the year

wow that is going to be one big tank.

you having to have that made just for you as the biggest i have seen in the shops is 6 ft.

Yes, I have only seen tanks up to around 125 gallons which is the same size of mine. I don't suppose there is much call for them, even my tank holds over one ton of water. My new one will have over 3 tonnes, that would fall through most peoples floors if they weren't solid concrete, which my garage is.

WWOOHOOO!!! THREE TONS OF WATER!!!! I can't even envision that.
THe tank I'm getting tomorrow (delivered) is a 125 gallon. Will be in my bedroom. LOTS of running space for my single oscar. (And yes that's all I want is just one fish).

Good luck with that and please let me know when you get it!! What do you plan to stock in such an ocean of space??

Is your garage heated? If not how is your climate? Because 350 Gallons of water will take quite a bit of heating effort and if your ambient temperature is significantly lower then the aquarium's desired temperature, you will need at least the recommended 5 watts of heating per gallon if not more. That would make a substantial impact on your home electric bill I would think. But it sounds absolutely grand! With that much weight coming I would want to make sure that concrete slab is not a thin slab at that. That would make a terrific Discus tank for sure. We'll need to see pics of course.... Good luck with this!

Actually, there has been a change of plan. My 350 gallon tank is going to be 300 gallons now. Instead of 9 feet, it is going to be 8 feet. Having said that, I am having a sump filter that will be around 60 gallons so I suppose the total volume of water will be around 350 - 360 gallons. I also can't bear to part with my two big Clown Loach so isn't going to be exclusively an Amazon tank.

It's going to be pretty good wherever, really looking forward to it

I should have made myself more clear, my garage is now my new play room, so to speak. My computers, radios and fish will all be in the same room now. At the moment, my fish tank is in my living room. I don't use my living room much which is a shame because it would be nice to be closer to the fish. Mind you, every time I go in that room at the moment, my little baby start begging for food.

You sound much like myself. I have a home office (extra bedroom converted to office) that I spend alot of time in when I am not travelling for my job. My 37 Gallon was placed sideways at the end of my desk (on a seperate stand) so that I could watch the fish while I was at my desk. Now the new 75 gallon is set up a few feet further away but still faces the side of my desk so I can enjoy the aquarium while I work.

I went with a 75 because this is on the second floor of the house and I was afraid of too much weight. I really wish I could have gone larger but maybe next time around. My last aquariums (120 and 65) were set up in our Family room but the good wife would hear no such suggestion this time around.

Well, my room is now all decorated. I had a guy come this morning and measured up for some nice blinds and I've got the carpet man coming tomorrow. My builder is going to reinforce the floor this week because I had to have installation put in. Thankfully, the concrete garage floor is only around four or 5 inches below so it won't take a lot to offer extra concrete.

And then comes the really boring bits, transferring everything from this room, into the new one. That is going to that take ages as this room is absolutely packed.

300 gallons...WOOW!!! I bet leveling is all the more important with a tank this huge. What do you plan to put in this mega tank???

I don't think levelling will be too much of a problem. I am having the floor reinforced with concrete so I am going to make sure it's exactly level. I'll take some photos tomorrow.

As for what's going in it, most of the fish I have at the moment. I was going to set up a South American Cichlid tank but I can't bear to part with my two large ClownLoach. So I decided to have a sort of South American theme but with a few foreigners. That being two Syndontis catfish and four ClownLoach. I also have my two red Oscars, hopefully a pair. I will possibly put two or three more fish in but I haven't decided what yet. Oh, forgot about my jade eyed Cichlid, might get a male for her. I might get a Severum. They are quite placid. Other than that, I'll have to wait and see.

I like the Green Severum myelf...
Good choice...
