Ok so here is my journal of my 5.5 gal. It is my first attempt at a Iwagumi style scape. Please feel free to offer any criticism or ideas.
5.5 Gallon All Glass Tank
Lighting = 2 x 10 Watt leds
DIY CO2 = 2 x 1.89L Ocean Spay Bottles
Rocks found @ landscaping store
Substrate = JBL AquaBasis Pro capped with fine black gravel.
2x Dwarf Neon Rainbow (temporary)
I plan on placing the rainbows back in my 65 gal and putting a school of neons in here along with some otos and maybe cory cats.
I purchased the leds and drivers from dealextreme, I was a little worried at first if this would be enough lighting, but so far the HC has begun to spread and even pearls sometimes, so i guess all is good.
The tank has been up and running now for 3 weeks. Once the plants fill in it should look pretty nice.
