minerals for corraline clusters

[beaslbob]

My nitrates have (finally) dropped to 0.0. And have stayed there for two weeks.

to add some color I have ordered corraline algae clusthers and condium algae clusters from florida pets.

My concern is that there may not be enough nutrients to keep those thriving. So what do these require? I have heard iron and magnesium. So is that correct and what are easy ways of providing those?

Thanks in advance

What about your live rock? I used epsom salt for magnesium and c-balance for alk and calc. I also used corraline stimulator from florida aqua farms.

Don't know about my rocks. they are mainly lava/land types with some limestone types.

Don't test my mag.

calcium is 400ppm alk is 2.5. Rose to 400ppm with the use of crushed oyster shells in my diy filter box.


I was thinking florida aqua farms also. only the plant fuel additive. have emailed them already.

patches of corraline are showing up.

thanks for reply.

I would pick up their corraline stiulator and try the epsom salt to save some money

For articulate coralline algae to grow you must have very pristine water (low nitrogen and zero detectable phosphates w/ normal phosphate test kits). It is important for calcium to be ~400-450 and for alkalinity to be within recommended ranges for most calcifying marine organisms. I am not sure what to tell you about the Codium. Please keep us posted on how these algae do for you and any advice you have.

Peace,

I've found coralline to be highly variable in what it wants.

Though kmk's statement is quite true, I will mention that hobby kits don't do that well at phosphate testing. In my experience, coralline is much like schleractian corals - with phosphate limiting calcification/growth.

But the lights/flow that a particular variety of coralline wants might not be in your tank. There are any numbers of colors/shapes/types that exist - yet for most folks only a couple colors/forms dominate their tank as their flow, lighting, and nutrient levels `fit' only a few varieties in my experience.

Good luck with it, will be interested how things go.
