It looks like you may have buried the rhizomes of java ferns. That may be why they are not doing well. Lift them up or tie them to driftwood.
Thanks, I pulled the one up and I do believe that you were correct, it was buried too deep.
I am liking the gbr - rummynose combo
Sounds good, haven't had a lot of luck find any locally, so still kind of looking at this stage.
I noticed this as well. Some things in your tank were ideas I had of doing in some of mine. I like it. Get those ferns out of the substrate and you should be good. Are you dosing ferts? With mosses I would avoid Excel, but have you thought about C02?
I did dose some Flourish nitrogen as well, and I also have some root tabs, but I haven't used them at this point. I really would prefer to avoid the CO2, which was why I was trying the Excel, what is the issue with it and moss?
