A question about my chaetomorpha

[kozmo02]

the top of my chaetomorpha turns yellow and brown, but underneath it is really bright green, do you think the top is getting burnt with too much light?

I have two of the LOA flood lights mounted on top of my 40 gallon fuge and the chaeto is about 6-8 inches below this.

thanks!

Too much light would be my guess. I had a similiar situation and tried 'submerging' the algae a bit more under the water surface with some coral rubble.

No more browning effect on the top portions. The lower sections are still a brighter green than the top though.

i raised my lights up about 4 inches instead, ill see if this helps.

i have mine under 65 watts...and a friend of mine
keeps his under a 13 watt...and it is that very bright
green all the way through...maybe the chato doesnt
need/like to much light...i wonder what depth it naturally grows?
does anyone know? Thanks Greg

Mine yellows in a few small places as well.
The brown is most likely an algae.
Look really close and pull some out.
