About five weeks ago I planted a variety of plants. Some of them (not sure
of name) had a beautiful copper/red colouring, however recently the leaves
are turning green. One that I particularly like has a corn type base and the
Lilly leaves float on the surface of the water. Roots appear to be good and
I feed with Seachem Flourish Tabs - No CO2. Any ideas on how I can get the
colouring back?

Thanks - Dave
