Pictures of this year's ADA Aquascaping Contest 1st place aquascape have been posted on CAU along with an interview of the winning aquascaper, Mr. Cheng Siu Wai. The aquascape is called "Danxia" and is quite unique. Check out the interview as well. Although the English translation is a little rough, it's still worth the read!
Expect the rest of the top 10 aquascapes to surface soon.
I've covered two other major schools of aquascaping for planted tanks before, but both of those are relatively high-tech, and high maintenance. For those of you who either don't have the time, patience, or just the wallet for a high-tech Dutch or Nature style tank, or for those of you who have been burned out by one, there is a third school.
This third school, often referred to as "el Natural," and sometimes Natural Planted Tanks (NPTs), is based on a low maintenance, low-tech approach pioneered by Diana Walstad. Outlined in her book, Ecology of the Planted Aquarium: A Practical Manual and Scientific Treatise for the Home Aquarist, the approach has several basic tenets:
- Regular potting soil, capped by small gravel is used as substrate
- No filtration is needed, aside from a powerhead for water movement
- Lighting is low, 1-2 watts per gallon, and is often supplemented by sunlight from a window
- No fertilization or CO2 is used, only liberal fish feeding
- Water changes are done only ever 6 months or so
- Plants will act as filters and fish will act as fertilizers, creating a balanced ecosystem
The end result is a tank that looks very different from any Dutch or Nature style aquarium, but that requires almost no maintenance, while maintaining a lush planted look. The types of plants available to someone starting an "el Natural" fish tank are somewhat limited, since lots of plants require high light and fertilization, but algae is rarely a problem. Unlike Dutch and Nature style aquariums, there is no set school for plant placement or composition of hardscape. This approach is also not designed for someone who likes to rescape their tank every few months, as moving plants around is difficult to do without disturbing the potting soil underneath the gravel. The natural soil substrate is probably the most volatile part of an "el Natural" style fish tank, and there are lots of do's and don'ts explained in Diana's book. However, once you get it set up, an "el Natural" style tank can be perfect for someone who is tired of dosing, testing, and re-dosing every day or for someone who just doesn't have the time for a high-tech aquarium.

Aqua Design Amano has recently launched a brand new English website called Aqua Journal Online. The website contains tons of useful information, including articles on Aqua Soil (which seems to be the focus for this first "issue" of the website), setting up a new Nature Aquarium, and some galleries of Takashi Amano's tanks. One of the best features, available under Suikei Data, is the ability to look at Amano's tanks and then be able to see the tank data, including size, lighting, filtration, plants, and more. Some of the sections aren't finished yet, but it looks very promising and there's already enough reading to keep you busy for a few hours, so go check it out!
In a previous article, I discussed what the difference was between submersed and emersed growth. Now, I'll show you how to set up your own emersed growth pots so you can experiment on your own. I've been growing HC, dwarf hairgrass, and moss emersed without problems. Stem plants probably won't do so well using this method, as they are much harder to convert. For quickly growing pre-made carpets though, this method can't be beat.
First, you'll need a shallow container. I use plastic Rubbermaid shoe-boxes available at most big stores like Target or Wal-Mart. They are the perfect size, since you'll want to cover your container with plastic wrap. Larger containers will also work, but may be harder to cover and keep sealed. Fill the container with about 1 inch deep of regular potting soil. Pour water in until the soil is just submerged but thoroughly wet. Then, take your plants and just put them gently in the soil. Once you have all of your plants planted, use plastic wrap to cover the container. You'll want a tight seal so the moisture doesn't evaporate. It might be necessary to use some tape to keep the plastic wrap from coming off. This will create a nice humid environment for your plants to transition to emersed growth so they don't dry out.
Once you have your container all set up, you can either put it in a sunny window or underneath some full-spectrum lighting. I chose to put it under a strip of lights (see above). Each week, just lift the plastic wrap up and using a spray-mister, mist the plants to replenish any lost water. Lifting up the plastic also allows new air to enter, replenishing any CO2 the plants have used. No fertilization is necessary, since all nutrients should be present in the potting soil.
Once your carpet has grown in, just gently lift the plants out of the potting soil, rinse them off to remove any extra soil in the roots, and plant them in your aquarium. It might be best to stick with one type of plant per container, since I tried HC, hairgrass, and moss all in one and they all grew together (see above). It makes it a bit difficult to separate, but very cool looking!
This method should work well for all mosses, most grasses, and most other carpet plants, like Hemianthus callitrichoides and Glossostigma elatinoides. Mosses in particular have very different emersed structures and can be quite cool looking. It's almost tempted me to start a palaudarium! Good luck.
I stumbled across this cool little tool today called AquaSketch and after playing around with it, figured it was worth sharing. It uses the Tropica plant paintings among other images to allow you to make a virtual 3D image of your aquarium. It takes a bit to get the hang of it, and the plants list is not by any means exhaustive, but the most common plants are included. The final result is rough, but very handy for giving you an idea of how a basic layout will look when completed. Just for fun, I made a model of my new aquarium. Even though you can only create rectangular aquariums and mine is a bowfront, you can get a decent idea of what it will look like. It has a glosso lawn on the left, with manzanita driftwood, crypts, rotala, and some moss on the right. Not too bad, eh? You can also save your layouts so people can view them in the original 3D format. Here's mine.
Over at ADA Thailand, they've posted some pictures of the results of their themed aquascaping competition called Beautiful Glosso. All of the aquascapes contain Glossostigma elatinoides, which is an old favorite of Takashi Amano for a carpet-like ground cover. The tanks are also all smaller sized tanks. There are some very interesting nano aquascapes here, worth a look! You can also check out the winning aquascapes for 2007's nano aquascape competition.
