My Coraline Algae Is Disappearing!

[basscyn]

<span style="font-family: Times New Roman;"><span style="font-size: 13px;">The coraline algae on my back glass is disappearing! This tank has been set up for about a year and the back glass has been totally covered with coraline. I just notice the other day that it is beginning to fade. I am starting to see the black background again. Calcium is good at 460. </span></span>

<span style="font-family: Times New Roman;"><span style="font-size: 13px;">Is this an indication of a problem??</span></span>

<span style="font-family: Times New Roman;"><span style="font-size: 13px;">The only thing I have done out of the ordinary lately is switch to Seachem salt.</span></span>

<span style="font-family: Times New Roman;"><span style="font-size: 13px;">Any ideas?</span></span>

I'd check mag next, for sure.

I will check for MG tonight!

I thought about SPS load. I have added some SPS and they are doing well. I just thought that since my Calcium level was always high...that would not be the culprit

You haven't added an urchin to your tank by any chance? Although I believe the algae they eat would be minimal.

Blue-leg hermies eat the stuff, too.

Personally I say congratulations.

No joke... I though I was the only one that hated the stuff..Looks good on rockwork.. hate it on the glass though

Hmm...I did get A LOT of blue leg hermits with some sand I just bought.
But they dont crawl up the glass.
Uhh...do they?:confused2:

Never looked at it that way. I honstly dont like it on the glass either.

But in the beggining when that first pink spot appeared on the glass...it was a sign of success! We were so excited to see it growing.
Then it went nuts and our black background became pink.

I would like to know why its happening though.

I'm with everyone else, I would check the Mag.....
one of those things that gets easily overlooked..

Some good info here:

Also in Coralline Algae 1, 2 and 4 (links are on that page for 3)

Good question. I see a decrease in coraline when I replace the T5 bulbs in my T5 lit tanks.

Also check your alkalinity....

seachem reef salt uses a lot of Borate alk to maintain high levels of Calcium, Mag, PH, & ALK, which you will measure as Total ALK. Corals & such only use carbonate alk. Make sure your ALK is about 2 points higher in dkh. So if you want 9.0, shoot for 11.

 

[skriz]

Have you had a lighting change? It doesn't like to ton of light.

 

[tattoocliff]

i would check the temp. if you are using digital therm., they are no good.
must use glass therm. the digitals are not accurate.
from past exp.

 

[washowi]

Heck I don't have any either....never really cared....


any reason why we should have it?

 

[roland jacques]

Have you guys found that lack of coraline growth usally equals slower stony growth or not?

It seems to me to always be the case with tanks i see. Maybe cause the tanks I see with low coraline growth, have high phosphates. The other thing not mentioned is lamp spectrum it seems to me to like the blues.
