Is my coraline algae dying?

[zoie2]

I posted this in the coral section, but haven't gotten an answer really. I didn't notice until I was looking at old pictures how different my coraline algae looks. It use to be bright purple:

But now parts of have changed color and the texture is different too. I don't know if it's just old or dying.

The only thing I have changed is the salt I use.
PH 8.2
Alk normal (doesn't have a #)
trites: 0
trates: 10
sg: .24
temp: 80
calcium 400

IMO its fine different substrates will show variences in color. Thickness of coraline will also make it darker than other areas that are not as thick.

have you changed your lighting? i was using power compacts and switched to mh and i saw a big difference!

I haven't changed my lighting, but it is time for my yearly maintence and my new ones should be comming in soon.
The only other thing I can think of is that my moon lights (LED's) don't work anymore. the cord got yanked out and the connection is bad.
Should I be concerened or is it normal?

Moonlight led's are mainly for astetics.. they dont have an impact on coraline algea. There are lighting systems that simulate the lunar cycle and at a certain time if done correctly corals will spawn like they do in the wild, but from what I have read its involved and not just moonlight leds. IMO your tank is fine.
