I really like the way your rock looks after you broke it down.
I recently planted an Eclipse 12, too. I thought that the lights were not going to be strong enough for growing plants but they really took off. After just 3 weeks I had to do a major trim, and I was able to use the trimmings to plant another tank.
I hope that you will post more photos as I am very interested in what other people are doing with Eclipse 12 tanks -- rather an odd shaped tank, if you're trying to fit rocks in.
Yours looks great.
