Building a nano - Doing It (lots of pics)


Im planning on building my own 2.1 nano in 5mm polycarbonate, with an integrated filter and CO2, and a polycarbonate hood with a CF bulb...

Heres a papermodel i made:

I plan on having a 20W 6500K CF as lighting in the hood, with a mirrorfoil covered aluminium reflector inside.

The filter and CO2 is integrated on back of the tank, and the filter has the intake on the back on the tank, like a HMF, but hidden in the back wall. Its gonna be driven by a 150L/h powerhead, and the materials gonna be caramic pipes and spongematerial/stuff. The CO2 tank (to the right), gets a bottle cap glued on, so i can refill and close it. The CO2 pipe will be connectet to the filter output.


So far i found a place to buy cheap polycarbonate (Lexan) and bulb and powerhead. The polycarbonate is far cheaper than glass and easyer to cut details in.

Any thoughts/comments on my idea?

whered you find the lexan? is it as strong at acrylic? I'm thinking of building a coffee table with a tank inside.

Coffee tables that are also aquariums aren't very practical. Just to see the fish you have to lay on the floor, unless you just look down from the top. Then, where do you put the filter, the CO2 tank, and store the materials you use? Even cleaning it would be a pain, plus how do you get it enough light?

I have found that cutting glass is a lot easier than lexan, You need to really scratch the lexan deep for it to snap straight where glass just needs a light scratch to snap. As far as details go, you are probably right.

I cut some lexan to use as a cover for my 60 gal tank. Its an acrylic tank and the 2 top holes are about 12x8 inches. I placed the lexan I cut over those spots to prevent excess evaporation. The next morning, the lexan was warped. Im not sure how that would work for a nano tank that is filled with water.

Hello,

I am interrested with your integrted filter and CO2 idea....

Could you please give us some details ????

Ill make a closed chamber to the yeast/sugar-mix - with a hole with a tread on top, so i can make a cap to the CO2 tube... Then i can refill when empty, and connect the CO2-tube to the output of the filter.
Then i can make a simpel CO2 diffuser and water output in one..

Ill order the polycarbonate soon - and will start right away

That was my guess...

But how will you empty the old sugar/yeast mix and clean the chamber before you fill it with new mix ???

I've read so many times that you have to clean very well the residues of old mixture before you go for the new one (in a soda bottle for instance...)....

Also I wonder how much CO2 you plan to inject in the water ?
And what quatity of water/sugar/yeast mix are you planning ?

Sorry for all the question but it is the first time I see a project of an integrated filter/CO2 in a Nano and I think it is really interresting !!!

I might be part of such an adventure in the very near future....

This drawing is a bit rough. The CO2 chamber should be the same size as the filter, but you can see the principle.

Water comes in thrugh the grid in the back wall, and is cleaned. Its pumped out in the top thrugh the outlet pipe, where the CO2 is injected. Hopefully this way i can dissolve the CO2. The holes in the outletpipe is directed towards the bottom/opposite side of the tank.



I wondered over how to clean the CO2 chamber - (Thanks Sietch) and dicided that a cap in the bottom would be the solution... That way i can just move the tank over my sink, and rinse the chamber with water...

The volume of the CO2/Filter-chamber issent desided yet, since i dont have the pump yet... But approx. 1/4 gal.

So 1/4 gal CO2 chamber - with 3,4 fluid ounce of sugar, 1 tsp of baking soda, 1 tsp yeast and 25 fluid ounce of water... This should give more than enugh CO2 for it to last 2 weeks...

Im ordering the polycarbonate this weekend, and hopefully ill will get it next week.
I havent figured out how to glue/silicone it together, but ill try and find the best way, and already got some good advice from scolleys tread
http://www.plantedtank.net/forums/di...lass-tank.html

Im probally cutting it with a saw, and then grind and polish the cuts.

But im going to do some testing before making the tank...

More questions please... There great help!

Hi Anti-Pjerrot !

Great drawings, helped to my understanding

However, I'm still not convinced about you cleaning method... and the airtighteness of your thread/cap
I've given it a bit of thinking and what I would do will be a plastic bottle of mineral water (500ml or 330 ml) inserted into you chamber (which would have no top).
That way, no need to move the tank for cleaning & changing the mix....

I have started my own design, and I think I will go basically for the same: a small side (square) chamber for CO2 (but in a bottle) and the rest for a HMF filter.

Question is how the back will look like when seen from the front ????

In your tank are you planning to have the mixture/foam/ceramics/cotton on display or are you planning a king of back decoration ????

You wanted more questions ????
Here you are

Hope not to be too much

Sietch

Im actually thinking of a mosswall - so that the back (and the filter) is covered. Then the moss will cover the grid and the filter will be invisible

Your idea with a bottle that fits in the CO2 chamber is great. I can possible get a square bottle - so that it can be fitted into the chamber. (Gives more volume for space...) And it gave me an idea - that i should make the lighting-hood cover both tank and chambers... like this:

Then the stuff will be hidden...
Thanks - more more...

Glad I can give you one or two ideas....

That canopy will definitely look better

On my side I will go open top with water up to the glass edge.

I am going to build a L-shaped support (probably plywood).
The tank will be on the base and the "tech part" of it (filter and CO2 chamber will go through a square openning inside the vertical part.

This vertical wooden part will raise above and support the light (to be determined yet...)
Pieces of wood will be added to the side to hide the "tech part" and also the electrical connections.

What I want to achive is you look at a cube of water staying on a L-shaped piece of wood

I am not sure it is very clear as I describe it.....

Still I am wondering on the view of the back.....

With a 20W bulb 2" from the water, I dont think is nessesary. But if i need to, ill use a heatingcable under the substrate...

But I havent thougt of it that much, since im pretty sure the bulb will do the work.
