Planted tank without filtration?

As long as it is stocked lightly and heavily planted yes. You will need to use a powerhead or airstone to keep the water moving however. I've got one of my 10 gallon tanks planted with just an airstone right now (no CO2).
 
Yup, just very light stock. I went to a public aquarium here for class and their quarantine tanks for naitives were just 40 breeders filled to the brim with plants and no other filtration.
 
You can...but the question is, why? For the challenge? It will limit your fish load considerably. It would be great for a colony of shrimp, a betta or some sparkling gouramis.

I would at least use a sponge filter, myself...
 
If you're using a powerhead, just use one of the ones with foam on the intake. That should provide enough area to act as a filter, and if you stay relatively lightly stocked and heavily planted then you should be ok
 
For this particular tank I plan on having zero stock in it. I want to use it as a project aqua-scape tank. I've been planning the setup of the tank for quite some time now, just finalizing on which plants are to go in it. I plan on planting very heavy from the start and then trim/groom to my liking. It's going to take a while for me get it just the way I like before I consider any sort of stock for it. I'm going to attempt to keep it low-tech, but if need be I will set up a CO2 system.

With that said if there is a great benefit from having filtration for plants then I'll go ahead and order a 3rd SunSun. Basically I bought a few tanks at the Petco sale and I have a have difference project planned out for each of them. Also another question... Would it be better to use a 40 breeder or a 29 gallon for this project? I could surely fit a lot more plants into a 40 gallon, I'm assuming this still falls under the "bigger more stable rule"

Def. for the Challenge! =) I have one of those in-tank Fluval filters. It's basically got a big sponge inside of it, but it does also move the water around some. I could throw that in there if it's a good idea.

I'll post pictures once things get going =)

Yes you can - google Leiden Aquarium (for the Dutch city Leyden) and who'll get a lot of hits on how to set-up and maintain one. But remember in this type of aquarium the plants are first and fish (what few there are) are secondary

Thanks for the info! I'm already finding lots of useful information.

Below are possible of the plants I plan on keeping, I'm trying to start out with plants that are hardy, grow easily, and require little to no CO2...

Foreground plants...

-Sagittaria platyphylla (Chilensis)
- Eleocharis parvula (Dwarf Hairgrass)

Mid-ground/Driftwood plants...

-Taxiphyllum barbieri (Java Moss) or possibly weeping moss.
-
Rotala Rotundifolia
- Hygrophila Polysperma (Dwarf Hygro)
- Hygrophila Corymbosa (Giant Hygro
- Cryptocoryne Wendtii
-
Microsorum Pteropus (Java Fern)

Background plants...Vallisneria Nana


If anyone have any plant suggestions for this type of tank it would be greatly appreciated!
