My coraline algae is turning white

[fishy7]

I noticied that my coraline algae is turning white. Anyone know what is causing this?
Thanks

Check your pH, check magnesium, check alk. Generally it turns white when they are by far.

have you recently changed your lighting or replaced bulbs?? Coralline can get burnt by a sudden increase in lighting.

also, is it all the way to the bottom? If you did a big water change and the corraline dries out before you get new water in it will turn white. (usually takes a while for that to happen tho)

Thanks guys for the direction. I will give the water a quick check tonight. I recently did a water change and pretty much all things are looking good.

It is time for new bulbs also.

I did add some new corals over the past few weeks.
I tested the water and this is what I came up with:
CA 350
Alk 10
SG 1.025
PH 8.3
Mag 1300
Trates 2
Trites 0
Amm 0

My coraline algae starts to turn white when my CA drops to 350. When I see it happen I quickly up the Calcium to 425 and the coraline springs back in a week or so.

What do you use to increase the Calcium? I recently rearranged some LR and I have a 4" square area of white coraline algae now. I don't know why it happened. The piece was out of my tank for no more than 5 minutes. I haven't tested for CA but would like to know which product increases it.
Thanks, Steve
