Berkley

Hello,
at first I wanted to introduce myself:
I'm 18 years old and I live in Hamburg (Germany). I still go to school. My hobbies are needless to say aquaristic, fishing, drive by bike/car etc.
Please excuse my not very good English (I'll try my best!)

Okay and now my 18 l tank, which runs since 2nd january 2007.
I used only Ada Aqua soil as substrate. I fertilize with Dennerle (V30, E15 and A1).
For lightning I use a desklamp with 11Watt an 6500K.
The inhabitants are B/W- and R/W-bees.
So, I hope you like it! It's my first "aquascaping-tank"...
That picture I sent to the Ada-contest:

Yesterday after redesigning:

(The red plants in the backround have to grow a bit higher; I cut them so low because they shold have the chance to root)
Please give me any hints, what I could do better or what's very good in your Eyes.
Thank you!
Regards Timo
