Heres's the setup:
16 gallon tank
I only have dwarf hairgrass, HC and moss.
What I've been noticing is the HC stems and leaves are somewhat flimsy, as if its ready to melt, but then I also see new growth. I know they are growing because I am trimming every 2 weeks. Do I need ferts? Here's a quick picture of tank and HC. Any advice will be appreciated. Thanks
