I have some live plants in my 125 freshwater tank..I am not using CO2 but have been added seachem undergravel plant tablets as well as flora-pride...I am concerned about the brownish color to my anarchis, you can see the one new plant growing out at the top is nice and green but the lower half of the plant is like a brownish-green (not sure if you can see it clearly in the pic). Also there are these string looking things coming from the plant as well, anbody know what they are? On the java fern all those brownish looking things will become new plants/leaves? just looks awful to me but as long as its good i dont care.
