For the most part I'm satisfied, not 100% of course. There is usually something I need to modify as plants grow out/mature and I need to tweak it a bit to avoid the great green blob look. I like trying new plants but if nothing is speaking to me I just experiment with what I have until inspiration strikes (or there's a deal just too good to resist on the temptation, uh . . . For sale/trade board). With my 7 tanks I'm usually happy with 5 or 6 of them leaving me the chance to play with 1 or 2 to bring 'em up to snuff.
