Chaeto turning white.

[Kaway]

Hi friends,
Yesterday I did notice that my chaeto into the sump are turning white. This never grow too much, but 2 days ago was fine.
I have started dosing alkalinity 1 week ago, can be that the issue?
My parameters :
Ammonia 0 (red sea)
Nitrites 0 (red sea)
Nitrates 0 (red sea)
Phosphate 0.03 ( hanna checker )
Calcium 440 (hanna checker )
Alkalinity 9 (red sea ) (was 7 a week ago and dose red sea part b slowly to bring up to 9 )
Any idea ?

The outline of my carbon reactor goes under the chaeto, what makes the water flows.

Chaeto and caulerpa will die off when not enough nutrients are in the water. It is a last ditch response and the algae goes into a spore phase so the algae can disperse and find suitable higher nutrient environment. You could try some iron dosing to increase growth. But I would get a test kit first so you can resume it.
