I have some java moss in there, I will look into some of the others. I'll be surprised if anything besides java moss grows, the LED
doesn't seem like it produces very good light fro plants.
As far as fertilizer goes, I haven't been using it because I was dosing my 40 gal
with 3-4 ml of Seachem Flourish once a week, and the next morning would have 5-6 dead shrimp. After the 3rd week it dawned on me what killed and I stopped. I wasn't losing any shrimp after that.
