Hi guys,
Not sure this is the right place for this thread, but here it goes:
I've noted that my live rock got some white spots on them.. It was alway pink in color. Now I've noted that these spots appeared...

Can it be that these white spots are "Dead spots"? Or is it something else?

Hi Raven

Sound like it could be, Could you post a pic?

how does your water test? have you cut the lighting time?
Aahh noooo....
I've tested the water last week. (only Nitrates and Phospates) The test was ok.

No i've not cut on lighting time.
Which water parameters should i look at?

Raven, could be any number of things. The sea is full of diverse and interesting life forms.

Can you post a pic ?

Do they look like small round spots, like something has been deposited there, like eggs?

Or is it white spots on the pink coralline algae?

sounds like coralline to me, it turns white due to lack of calcium and some sea urchins also feed of coralline

Thanks guys!
I've tried to take a picture of this, but I can't get a clear enough pic....
Yes it is the coralline algea that's turning white..
I thought that it might be a Ca shortage...

Now another question:
What testing kit is the best value for money?
The reason that i've asked is that my test kit's results and the results from tests done at my LPS differ.. And the difference was not small!!

And Yet another question:
How long do you think the white spots will disappear after I've made corrections on my Ca? (Hope not to long....as it took my a couple of months to get these rocks as they are now!:1hissyfit: )

Hi guys - there are many things that impacts the growth of corralline algae. Not only calcium.

You must test you alkalinity too, as well as phosphates. Too low alkalinity could have an effect. Too high phosphates too could have an effect (negative).

So - please post these parameters too....

Also - to be 100% sure - I too agree that we would require a picture.....
