Yea, flourite was the the easiest thing for me to find as well.
Truth is, I've got microsword in the foreground, and I like the green against the red & black. I think the red would have been a bit much IMO.
However I'm not having much luck with it due to algae. Could be my tank isn't mature enough.
I just picked up some eco-complete at Absolutely Fish...it was expensive, but I think its worth it. I also picked up some fast growing stem plants while I was there for my new 20 long tank. Spent a lot of money today!
