I'm an in betweener leaning more to the Satisified side. I am happy with the plants I grow and am starting to learn about and enjoy aquascaping. Since I have about 25 -30 different species of plants in 11 tanks, I have dedicated 2 tanks that I mess around with a new aquascape every few months or so. 1 tank is CO2 and the other is excel, both are EI dosed. So far I'm happy with my layouts as the plants are growing in nicely. I will definately start over on the excel tank during xmas break and rescape it. I will try new plants (mosses, the rare and the unusual) as they are offered from friends and in the club meetings but I am not actively seeking out any new species of plants at this time.
