My tank has been up and running for about 4 weeks now and I've encountered some problems with the plants and fertilization.
Tank specs: 20 gallon paludarium w/ ~10-12 gallons of water. Eco-complete substrate, PC lighting (65 watts), plenty of water circulation (estimate around 200 gph), filtration in sump (just some cotton batting). The tank is unheated (temp ~65-70 F).
Inhabitants: 4 white cloud minnows, 1 butterfly loach, 3 red cherry shrimp, 2 amano shrimp
Plants: hygro siamensis, hygro rosenvarg, hygro polysperma, bacoba carolinian, glosso, xmas moss, and ludwigia repens.
Currently, I have flourish potassium, flourish phosphosus, flourish excel, and flourish trace. I have been unable to find a suitable nitrate source locally, but I ordered flourish nitrogen online several days ago. I have attempted a yeast CO2 system, but it has failed due to a waterfall in the tank. I am currently modifying the system...so it might contribute a little bit once completed.
Most plants are healthy (except the glosso), but some sort of brown hair algae has smothered the moss and glosso. I pick it off with tweezers nearly every day, but it comes back quickly. A good amount of the moss is dead (from travel) and rotting--does this promote the algae growth around the dead plant material? I've tried to clean off the areas as best as possible, but I'm afraid of disturbing the new moss growth. Spot and brown algae have also flourished. The loach has kept the brown algae under control for the most part and the spot algae isn't much of a bother.
Anyway, my main question is this: how heavily should I fertilize this tank? As far as I know, most of the plants I have are fast growers. I haven't put any fertilizers in the substrate--should I? I have some Jobe's plant sticks on hand for my terrestrial plants. The glosso in particular isn't doing very well (I guess this should be expected considering the lack of proper fertilization and CO2 injection).
