No co2 or anything like that. Filtration is a Seachem Tidal 55 with an ACO prefilled sponge. Inside is 2 layers of Seachem course sponge, polishing pad, purigen, and Seachem Matrix. I also have a medium ACO sponge filter on the side opposite the Tidal. My substrate is pea pebbles. I may do valisnaria in there as well but wanted to start small since I never did live plants before.
I also like the idea of a gourami...I was looking at some powder blue dwarfs but read the temperature may not be suitable.
