Hey Len. Beautiful setup man. Keep it up.
I also have some questions. I have an emersed setup, and wanted to know how you are growing Java Fern in yours. I have mine in a tub of water in the setup. What I am wondering, is how much light you have over yours, what your water level is at, and how you fertilize it. Any help would be great, thank you.
P.S. If you need to see my setup, it is in my signature.
