Looking for ideas for large indoor tank

[c_scherer123]

Looking for some ideas, information, or even links to previous threads.
I am hoping to put in a tank for a couple of koi (roughly 6'x8'x2.5' or somewhere around that size).
My problem is that it needs to be something I can take if I move (which is likely in the next 5 years). And, the way the doors and hallways are arranged, it will likely have to be able to come apart to get in and out. (Otherwise, I'm limited to 5x6.5' - since that's the size of the bed mattress that we barely squeezed into the house).
I do want glass on at least two of the sides so I can see it from my desk.

Also, what sort of humidity should I expect from an unheated tank of that size?

Anything else I should consider?

I really like the looks of the Instantpond, but leary about the chances of it leaking as well as how their site/FB page hasn't been updated in over 5 years. The price is also making me wonder what else might be more readily available in North America.

Have a look in this thread bud.

Compilation of DIY plywood tanks (Load Warning)

Just wanted to start a thread that some might find helpful/interesting. We have quite a few threads on plywood tanks but there really isn't a one stop place to sort through them all. So I decided to make a thread dedicated to highlighting plywood tanks on MFK. There are a few rules for what I...

Easy done to take an tank apart. This tank is in 5 sections. Bottom and four walls. You chuck in an pondliner and your good to go.

For what youre thinking, a plywood bottom tank with glass sides would be my suggestion. Easy enough to take down and reassemble. The glass will definitely be costlier than a full plywood build.

Im currently planning a 6'x6'x28" build myself with donor glass panels from an old 150 and even older 220. Still unsure what to do for the bottom but im leaning towards plywood/pond shield.

So if you were to find an old fixer upper 300 and 220 on the cheap you'd have all the glass there.

This is my thread and concept on doing the same. I've did some elementary drawings in Sketchup as well. Any questions feel free to PM me.

Thanks! I'm off to do some reading and research! I wasn't aware plywood would work for a tank of this size - or that I could design it to come apart if needed.
Do any of these threads cover what kind of bracing I need across the top? I'm hoping for no cross braces across the top since I want it to double as a small pond to view the koi from above.

To avoid top braces, you have to go thicker on the glass. My drawing in my thread has the eurobracing, but will still utilize cross braces.

I would not build an large tank without bracing at all. I have three crossbraces. My tank is 100cm high and the glass is 83cm high 15mm tempered glass.
