Absence: "The beginning is the most important part of the work."

Some Prelude:

Two weeks after setting up and aquascaping a 10 gallon tank, I had an opportunity to get my hands on a 20 gallon tank. It was a big decision whether or not to break down the 10 gallon and upgrade to a 20 gallon because of all the work I had put into getting the scape just right, but ultimately this would allow me to have more fish and a bigger scape. I sucked it up and started siphoning water...
(The 10 gallon was running a Marineland Penguin Bio-Wheel 150, a 50 watt heater, and a 40 watt Single Satellite Compact Light. The substrate was Seachem Flourite. It was originally planted with Anubias barteri var. nana, Hygophilia difformis, Echinodorus amazonicus, and Potamogeton gayi.)

Certain upgrades were necessary to switch from the 10 to the 20 gallon.

Filtration: Rather than upgrading to a large filter I decided to get a second Penguin Bio-Wheel 150. The reason for doing this was to not only increase filtration, but to encourage more water movement as well as have two sources of biological filtration that way filter cleanings can be alternated. By doing this, the hit the bacteria would take during a cleaning would be minimal.

Heating/Lighting: For heating I considered getting a second heater, but decided to upgrade to a 100 watt. The only reason for this was aesthetics. I upgraded the lighting from 40 watts to 65 watts. This was actually a downgrade in wpg from 4 to 3.25, but considering the plants I am planning to grow this is adequate.

Tanks setup began with adding substrate and brainstorming ideas. I had a wide selection of rocks that I collected from the coast of Maine and a nice piece of driftwood that was in the 10 gallon tank. I had originally planned on making the driftwood the center piece of the scape, but quickly abandoned that idea and dabbled with making the entire right side of the tank elevated. I did this by using large pieces of rock to hold back the substrate. I then decided to put the piece of driftwood in that section. To add to the topography of the tank I used another large rock to create a slightly lower elevated section in the back left corner of the tank. I had now created drop off in between these two elevated sections. I used some smaller pieces of rock to create a 'bridge' between the two sections The final effect looked like a horseshoe rock formation that was integrated into the elevated sections of the tank.

I planted the Anubias from the 10 Gallon around the drift wood and added a Giant Hygro to the elevated section on the left side. Riccia Fluitans was added to parts of the rock horseshoe. The Amazon Sword was planted behind the driftwood in the back right corner to block the heater and filter intake from view.

In the pictures below you can see the tank setup...
(My apologies for the cloudy pictures, but it is very hard to fill a tank with Flourite without mucking up the water. Once it clears up I will add new pictures.)
