So I was at The Fish Store the other day and noticed they had a huge overflowing aquarium. It overflowed on the sides and went down the glass into a chamber to get pumped back up to the tank. If you don't know what these are heres a link:

Anyways I was struck by how awesome these were and went home and looked them up only to find that they cost an insane amount of money. So I decided to build one on my own, granted not as big. This is the first build of any kind I've done so there has been a good amount of trial and error. I decided to buy a 5 gallon tank with bowed edges, as water will push away from sharp edges and it does not create the intended effect. Next I wanted to build the lower chamber with a bulk head built into the bottom leading to a pump to pump the water back in. I was thinking about doing a mini sump from the overflowing water, but the tank Im buying already comes with a mini filter so I decided against this. This left me just a tube and a water pump sticking out in the open as well as a bulkhead coming out the bottom. This led me to decide to build a mini stand underneath the tank to house the equipment. Its all elementary and was build the cheapest way possible so bear with me.

My work station:

Cleary Im a professional. Atleast I wore safety goggles.

I began by picking up a large piece of polycarbonate from home depot as well as a cheap jigsaw. I measured out the base portion of the tank to be a slight bit larger than the frame of the actual tank. I cut out the pieces and taped them together.

I then used GE Silicone I to glue it all together, let it dry overnight and water tested it.

Oops. That didn't hold. I later reapplied the silicone and deemed it watertight.
Next was the bulkhead. I used a small drill bit, all I had, to make a small hole in the Polycarbonate and slowly but surely expanded it by rubbing the edges. Eventually the hole was big enough and I attached the improvised bulkhead

I found a 2x4 laying around the house and cut it up to make the stand

Test fit was pretty good.

Then I found some random Eucaboard lying around my house, looks like this, and used it to wrap around the stand to give it a more finished look.

Finally I painted the outside of the base of the tank shiny black. Probably needs a few more coats.

Still need to decide what color to paint the mini stand. Im thinking either shiny silver or black again. So thats as far as Ive gone so far. Waiting on things to dry. Any thoughts, tips, ideas would be appreciated. Again this is my first build at all so it might be lacking some important things that have slipped my mind. I need to figure out center bracing for the tank. Maybe a piece of 2x4 underneath. however if the actual tank edges sit on the 2x4's do I need center bracing? Again any thoughts or tips are appreciated. You can tell me Im an idiot for doing this, I won't cry haha
 
Cool concept but I believe i would interject the use of acrylic solvent instead of silicone. Water pressure against an unsupported end will eventually push one of the ends off causing a extremely mad "ol lady" and a big mess. The solvent melts the acrylic and bonds the 2 edges together versus a "press fit". Just my two cents! Good luck
 
Great idea, silicon will hold acrylic short term but for a permanent bond weldon will chemically weld the acrylic together. These tanks have to be spot on level to get them to work correctly so the water flows from all the top surface area.
 
In addition to the aforementioned leveling, you'll also need to bevel the edges VERY evenly to get that smooth cascade effect across all the sides of the tank - otherwise you'll end up with some "waterfalls" and dry areas.

Still, I don't mean to be discouraging... keep us posted!
 
Good idea, but if you use silicone the tank will fail. Use a solvent like Weldon. I would never set up a tank like you have it now.
 
Thanks for all the feedback. I will look into ripping off the silicone and redoing it with weldon. The way I designed the tank is such:

I will actually buy a five gallon tank to put right inside of the contraption I build. The water will then overflow into the container I built and be drained and repumped through the bottom. The reason I didn't put much work and thought into the building process is that there will only be around two cups of water flowing through the bottom chamber, which is not nearly enough to make any micro fracturing a problem I believe.
 
Update: I had put this project aside til I got my paycheck. Now I will slowly get back into it, starting with re-glueing the base part with weld-on. Soon she'll be a beaut.
 
So I took the advice of many kind people and decided to rebuild the base. I decided to take the old one apart and the silicone came apart in one piece lol

Anyways I rebuilt it and used stronger stuff to hold it together. The tank also arrived so this is them together

Also drilled another hole for water to get pumped back into the tank

I can't decide whether to keep the base clear or paint it black like last time. I will also be rebuilding the stand to look something like this

So thats where I am now. Have I done anything wrong again? I don't wanna finish and find out I did something incredibly wrong again haha
 
Good idea for a DIY.... If you would like to come up and get some ideas from mine, feel free.... I love mine! I will say that it will be a difficult build to perfect.... Even though mine was still from Zero Edge, to get the water to flow evenly was a task! I filled and drained 4x until I got it right.... One thing to note on the construction of mine, the front and 2 sides are 1 piece of acrylic that were formed with a 3/4" acrylic as a back piece (not something I could do in my garage, lol) .... I have also noticed that the construction of the edges are very precise and smooth. The catch tray around the tank is also about 2 1/2" wide and 3" tall along with two 2 1/2" drains (you will soon find out why the tray and drain is so big)...... After all that is done, the req'd pump by ZeroEdge is a SpeedWave DC 10000, 2640gph, (thats ALOT for 46g!!!) Take a look thru my build thread on it

You may want to consider either adding some adjustable feet or a floating surface to the top of your stand. Admittedly my own DIY skills are practically nonexistent and you've come a long way on this - but if you can't get the tank completely level the whole cascading effect isn't going to work, and that stand doesn't appear to be.
 
I read somewhere that these tanks actually don't have to be perfectly level, just close to it and the flow will compensate.
 
Small update:

I will definitely look into the adjustable feet so I can make it perfectly even. But for now its looking good
