Coraline algae growth?

[elegance coral]

Why is it that my coraline algae will grow everywhere but on my rocks? Its growing in the overflow, on all the glass and plumbing, but not my rocks. The coraline on my rocks seems to be fading. Why?

Im experencing the same problem. I finally got my calcium test kit and found that my calcium level was down to 280. I have started adding supplements to increase the levels, now that i have a test kit.

Ive also read that with depleated levels of magnesium can also cause this problem , Im still wiating on my test kit, but I suspect that my levels are low. will not dose to much mag without a kit, but these are parameters that you can check.

Beyond this I cant help.

Good luck and I hope this helps.

Chris.

Thanks. I dose with kalk and don't really have a large demand for calcium in my tank so this shouldn't be the problem. I think maybe my lights are to bright over the rocks. I'm not sure.

I keep getting lazy/forgetfull when doing water changes, and dont turn off the lights.

Im going to have to start doing water changes after the lights go out. I wouldnt think the little bit off evap would be enough though
Ah well you live and learn

I think it might have to do a lot with lighting, I have a 12hr photo period and have absolutely no coraline growth on my rocks, glass or anything.

I do have some white coraline looking stuff on my rock but nowhere else.

In my experience flow also has alot to do with coraline algae, the more the better..

Coraline does not like high light. It does like for you to keep your Ca / Alk and Mg in line.....
