coraline

[brent_mclean]

I've been in saltwater for a year now and keep my water pretty good.
calcium 450
nitrates-0
nitrites-0
ammonia-0
phosphates-0
alkalinity-10

I don't know what is wrong but i can never grow coraline. What is wrong here?
Thanks

Count yourself lucky, I would love to not be able to grow corraline algae .

What is your Mg level, growth seems to slow considerably when magnesium is low

I've read hermits and urchins can both eat coraline. If you have several maybe they are preventing growth?

I don't have coralline in my tank either...well very minimal anyway. I have "perfect" parameters including magnesium. The only thing I struggle with is low pH at around 7.8-8.0. I'd also like to know why I can't grow coralline.

Marie: You wouldn't like it if all YOUR rocks were stark white!!!! :P

What kind of lighting are you using?

Maybe if ya quit cookin 'em...

Brent: Do you have any coraline at all? You have to have at least some to seed other rocks, glass, ect.

^ Haha! I didn't have any before I cooked them either. I do have some on one rock. I find my coralline grows better on the shady side of the rocks... ??? Weird.
