I have been keeping my Xmas Moss for about 6 months. Mainly on drift wood. Some on top with direct light and some at the bottom shady area. I notice the top part are slightly Brownish green. Can anyone advise what i can do. Temp is about 25-29 deg. Day time up to 27-29 . Night to morning 25-27.

We need to know afew thing:
The time light were turned on
Any co2?
Any fert?
When u say top and bottom, how much is the depth we are looking at?

Probably my guess is the top portion are getting "burn" by the long photo period. 2nd guess, when temp goes ago 28, they start to turn brown

My light are from morning 0700-1000hrs. & 1800-2200hrs. 50% of the light are off due hair algae problem now.
CO2 1-2 BPS from 0700 - 2100hrs link to my fan timing.
fert : I use tetra florapride once a week.
Light is about 20 cm above the plant

When i turn on 100% of the lights. The tanks looks very nice and bright. The rotala is very pinkish. with the reduction of the light.. the rotala now become orangy colour. no more pink... too much light, i think the moss also cannot take it...
