US fissidens turning light green to brown

[kev76]

Hi all,
Recently bought some nice us fissiden on driftwood from a forumer here. But after few days in my Crs tank, they start to turn bit light green to brown. May I ask wats the likely cause . My lighting is on 4 hrs 24w with chiller...may I ask could it be due to lighting too short or maybe not strong enough? Thanks

Hi Kev76, your 4hrs is too short, even though US fissiden can do well under shade you should lengthen your lighting period to at least 8 hours.

4 hours too short? Initially i thought the plant was burnt. I have this problem on those that i tied on the top of the branches, and on the lower part of my DW was fine.
