My new and improved 20L, converted from a Walstad tank. It now has Eco-Complete fine grade, with a thin layer of peat at the bottom. I also splurged and got some new plants. :) The only thing I still have left to do is put some moss on the coconut cave, but I'm waiting for my LFS to get some Christmas moss in.
