Default How's this for a first nano?

Today in Ikea I saw an small "almost" cube glass vase and decided to purchase it and try my hand at a nano tank.

Tell me everything that I've done (or am doing!) wrong!

The cube is 13cm deep (5.1"). The top is 13cm x 13cm and the bottom is 10cm x 10cm (4"); that's why it's "almost" a cube...

So the thing holds about 1.7 liters of water (not even 0.5g).

I put some Flourite on the bottom and planted some HC, Hydrocotyle verticillata and a small Crypt wendtii. As soon as I find a small enough piece of wood that'll change.

No fauna yet. Maybe a shrimp? or a male guppy?

The only light I could find that fits is a 20w small halogen lamp. I think I remember reading once that halogen is not at all good for plants but don't know if that's a myth or not. I guess I'll find out!

No filter and no heating. I added a drop of Flourish and a drop of Excel.

Typical... my first try and I choose a tiny tiny nano. I could have gone with a 10 liter or something like that but no...

With such a small water volume, the radiant heat from the halogen will likely make your "tanK" a weeeee bit toasty. I highly suggest you get a screw in compact. Home depot sometimes has some 19watt 6700K ones. There are also plenty of LFS's which sell the 9-11 watt double-U screwins.


The wendtii will be WAY WAY WAY WAY to big. Try wilisii or maybe some parvulus (smaller hair grass).

Gomer, good idea, but Laith may be hard-pressed to find a Home Depot in
Switzerland

I know the wendtii will get too big. At the moment it's very small (about 2") and comes from an emersed growth I have. First I'll see if it grows at all which will be a sign that I'm doing something right!

The light is about 3" from the water surface and doesn't seem to heat the water up at all...

Laith, Tropica uses a halogen lamp on their Aqua Cubes. The lamp uses
either a 10 or 20watt bulb. They have a slide show that shows how the
cube grows up to 67 days, pretty cool.

Thanks for the link to Tropica's aquacube. They don't give the volume of the tank but 5kg empty and 13kg full is 8kg difference. If that difference is all water that makes the volume 8 liters. Say 6 to 7 with plants and their coconut thing. And they're lighting this with a 20w halogen like mine.

So 20w may be too much for my almost 2l.

What's the consensus... do water changes or not?

It has not fauna as yet but will probably get a Caridina Japonica shrimp soon...

Yep, pics would be a boon....you could change the bulb out for 10W one and
I'd just top off with RO or distilled when it evaporates, unless you overfeed
the shrimp(?)

GE makes a 20W halogen that has a white, clean light that I'm using: part#
PC: 19375 Desc: Q20T3/CL/CD made in Hungary, not particularly cheap:
online they are 6 for $35, and at Walmart: $10 for one. The cheap ones I got
at Lowes and Home Depot throw out a very yellow light. Too bad GE doesn't
make one for 10W, maybe they do, just haven't found it yet.
