spiky moss turning very pale yellow. help

[kennyseah17]

I have spikey moss tied to a drift wood in my tank. However since planting 2 days ago.. the colour seems to be getting 9 light green and I think they may have been melting. There are some leafy plants (not sure of the names) also melting. I suspect I may have a blind spot for lights because the design my tank blocks out light to that side ( approx 10 cm x 60 cm in area ). however the plants in the center seem to be thriving. vivapara are growing very well and hairgrass seem to be crawling.

If it is the problem with light ( blind spot ), I may have to find a way to fit a light at that side however will it be an over kill?

My tank specs
Water capacity : 200l
Chiller temp : 25 deg
light : 192 w mixture of 12000k and 7600k
fishes: none ( tank in cycling mode )

I will try to take a picture later as there is no light now.

Must be really dark for it to turn yellow. Shift some of the moss into the lit area and compare results in the coming days/weeks.

Ermm... If you read my first post. I got 192 w of light in a 2x2x2 ft tank.. Should not be too dark

Mosses do turn yellow when there's too much light. You did mention a blind spot? Something that can't be seen from? Sorry- don't understand your question.
