I picked up a lily, put it in my 60 gal. pond.
I woke up this morning to find the water all milky. I did a water
change, but the water was a gray milky color again.

Today when I got home from work I took the plant out, washed all the mud
out and left only the round bark and roots.
I took pea gravel, put the plant in a terra cotta flower pot, then put
it back in.
Do lily's have soil?
If so.
What kind of soil?
How deep?
