coraline

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

[Starry]

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?

my lighting is 150w halide over a 20 gallon. the only thing i have never checked is my magnesium. i do have some coraline on the rocks that it came with but it has not grown at all. i don't know what to do

I started adding about half the recomanded dose of Purple Up to my tank once a week and i have been getting pretty good growth from it.

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.

I've always been able to get good coraline growth on rocks but never seem to get much on the glass.
