wow, thats sweet it took me like 3 months just to let my parents let me set up a 20H in my room and ive been begging to get a bigger tank for my basement.
I like the black sand one the best. I would put a black background on it though & lower that beautiful bubble wand. LOL It will look much better if you can't see the actual wand as much.
I wish I had all those when I was a kid. I always had a few small ones but nothing more than a 30. I would like to see your house in about 15-20 yrs.
