I'm building a house later this summer with my dad. And in one of the main rooms we want a giant wall sized tank.
Anyone ever built there own tank and could shed a little light on the subject?

I built my own 90+ gal. with 3/8" acrylic. Questions, is how big, and are you going with glass or acrylic?

If you can buy a tank and put it in the wall I would feel safer about that.
Though I have seen quite a few websites that have in depth information on how to make your own, so they are out there.

I'm on the fence glass/acrylic This tank is not going to be small. It will literally take up a wall. Its too early to tell because we are going over house plans right now, looking for something that will accommodate what we want to do. Which is why...due to size...I will probably go acrylic.....with a possible glass panel face/cover on the front, to reduce likelyhood of external scratching.
General ballpark size I'm thinking no less than 72" long(more than likely 96"). And 48" to 72" tall. With a depth of 32".
This means It will be anywhere from 500-950 gallons.
The theme will be a foam wall build similar to my 125, but on a bigger scale, to give the impression of a continental shelf drop off....the solid wall look of a tall tank that has the corals growing all the way up. I want people to be able to stand and sit and still feel like they are floating off the edge of a continental drop off. Or at the very least feel like they are staring at a solid wall of corals....not a lame pile of rocks sitting in the middle.

Yup, I'm reading a lot of sites. I know very few people in this community...if any really have dealt with tanks this size. But since its something that is DIY...my dad is open to adding it to the cost of construction.
Now if you start talking 40-50k just for a custom tank this size to be built and delivered...then flat out no, not happening....but if its a few grand to DIY a massive tank like this, then that is a feasible thing to add to the cost of the construction.
I've seen 180gal bricks built for under $250. So how much more could something 3-5x the size cost? Evin at $2,500-$5000 its doable considering it would be figured into the cost of the construction package. The real killer is going to be 2 years from now when the house is ready and finished, and we go to put in the actual Reef equipment....ouch. That will be a fun time^^
But Im pretty good at saving a buck, so Ill cross that when I get to it.
Right now, I just want to lightly test the waters on the whole DIY build your own tank thing.

Great find. Thanks. This is looking like a feasible project. Well have to use the backhoe to lift it in place But I think It can be done.

i can tell you i have no plans on building a tank. putting the baffles in my sump was enough for me

i would look into a plywood tank for something this size... seems fairly easy and cheap to do... for in the wall i think this is the way to go... i found a couple good sites awhile back on these builds that showed things step by step (sorry i dont still have the links)...

I am building a house now, also. I'm going to build in a hybrid tank, for durabilty and ease of installation. There's a thread here in SWF about using plywood for 3 sides and 1/2" glass for the display side. Since the aquarium room is going to abutt the garage, I won't need a see through display. The cost and lower chance of installation problems, make the plywood/glass wall tank quite attractive. I leave the back wall and sides of my 125g reef tank "natural" to give the angels, tangs and butterflies a constant supply of algae anyway.

Are you building the tank in place and then painting it?
Or, are you going to build it outside and keep flipping it over so the side your painting is always on the ground?
Reason I ask....Building the tank in place seems like the safest, and surest way to get it done right.(not to mention trying to use the backhoe to lift it into place. But coating the vertically standing walls seems like a gray area to me. I only have the one link above as a reference, but he kept flipping the tank so the epoxy would dry on the bottom.

For that size plywood IMO is the best bet with glass. Acrylic scratches on the exterior is your least worry, it is when they happen on the inside. It is a giant PIA! If you decide acrylic you can PM me with any questions. I learned some valuable tricks along the way, especially with the adhesives. If you choose glass it is going to be HEAVY! The glass shop I worked at installed heavy shower enclosures and the doors were very heavy. They were either 3/8" or 1/2" tempered pieces.

I've no experience with building a tank from scratch, But I have looked into it a few times, From what I read anything DIY over 500 gallons It was suggested the tank be built In place from Concrete rather then Plywood.
Your talking about a Tank that will weigh in excess of 4200 lbs once filled, And thats the lower end of the scale (around 500 gallons)
Thats a lot of plywood and support braces...
Personally were I to ever do this, I'd go with poured concrete supported by rebar and either a formed concrete groove, or a machined metal groove secured into the concrete and allowed to set in the concrete itself, Sliding the only Pane of glass used (though I suppose acrylic could be used as well) into the groove and securing it with adhesive (Probably silicone)
If built correctly the weight of the water will actually push the glass against the concrete.
Granted this does require pretty extensive construction, And more importantly headroom to slide the glass down, though the concrete could be carefully formed around the glass I suppose.
While It would be Expensive, If you do it all yourself cost should stay surprisingly low compared to the what you get out of it.
Though having it contracted I'm sure the price would be astronomical.

I do not know of the construction on such a large tank but I guess the concrete would be supporting the plywood. Is concrete sealable for a tank? I do know of a product that would be safe and waterproof. I know Drylock makes a concrete sealer/paint but what about leaching?

i think that with the expansion and contraction of cement with weather changes could cause problems if you use the concrete 'lip' like ryanpaul was talking about. it could cause the glass to crack if it expands too much, or the glass could give way if it has enough room to move in the case of contraction.

i think that using cement under the tank is an awesome idea though. neptune, if you're able to build a room behind the tank and water proof the floor and stick a drain in the floor, that would be clutch.

I did the reading and yes, I agree 100% I will not do it out of glass or acrylic. It will be plywood coated with epoxy, and a glas spanel front that will be lowered in place form the second floor, before it is completed.

Most custom construction jobs are pricy. Fortunately My brother ownes his own engineering company, the design logistics are covered. My dad is a retired contractor, his homes have recieved national recognition and have won compititions before. He knows his stuff.
Price accually will be relitivly low and figured into the construction package.
To put it in perspective:
The last house he built was done for less than 100k( I think it was a 90k loan). It took a while, because he does everything with meticulous perfection. But the house appraised last year at 450k. Granted..the econamy took a slide, and its proably only 300k but you can see how he takes a little, and makes it look like it was way more expencive to do.
In a nutshell, adding a tank this size to a house during its construction will have very little impact on over all cost. I would guess concrete, re bar, plywood, epoxy will only be a few grand if that. The most expensive piece would be the glass panel that slides down into place from the above floor.

Ya my brother will go over house blue prints and alter them as needed to accommodate this kind of weight. Im quiet sure pops will pour a special foundation slab directly underneath to support the massive load. And most likely weld a steel frame to house the tank. His last house had a rec room up top that could fit a city bus easy, both weight and size.

We haven't chosen a floor plan yet. But the basic Idea is a larger than normal living room with a tank against one wall, with a utility/laundry room behind it for all the filtration and other gear to be stored out of site. this is all in the inital stages. I'm just gathering Intel for him, he hasn't evin committed to it, but he has sparked interest in a tank actually built into the wall, and has activly engaged in asking about all the logistics of doing it.
I would say the chances are improving every day that this is something he will commit to when we break dirt later this year. Ill be moving out to his place and living in the guest house in a couple months. I agreed to help with the construction for reduced rent and the freedom to attend school for the next 6 years, while I live with them. Who knows, mabee when I finish my masters, Ill buy the house from him^^ now you see my motivation for this fish tank ha ha.

I wonder how exactly the public aquariums with concrete tanks do it personally. I assume there is something that can be used to seal it, and I'd assume they would include room with a flexible seal to allow the concrete to expand/contract without breaking the glass... who know.. best of luck though..
