What kind of fertilizer should i use?
Hi, I was wondering which fertilizer should i use? That is betta safe? Or are they all betta safe? Any fertilizer i should avoid?
Are there more simple fertilizer that is cost efficient?
I currently have some duckweed, frogbits, dwarf lettuce, 5 java ferns, 4 different types of aponogeton, java moss, 1 water onion, 1 banana lily.
