hc is kinda iffy most of the time people do a dry start with it any way to let it fill in before filling the tank. i have several kinds of plants in my fss. ive had hc in fss but the shrimp tended to pick it out of the substrate but i didnt give it good time root either. i have marsilea in it right now and its doing well and i also have one of the small grass crypts all i can remember is it starts with a p lol
I have a cherry shrimp tank with fluval stratum (the red bag) for 2 months.
I have been able to plant saggitaria subulata in 2 inch substrate.
There are new baby plants spreading all thru the aquarium.
I prefer hardy plants who need very little ferts in a shrimp only tank.
I use Jbl 24/7 two drops twice a week and 5m"l of JBL ferropol when I change 20% water once in two weeks.
My plants are fine no yellowing, rotting or dying coz I have easy plants like Java fern and mosses.
