Coralline or not?

[seanocode]

Is this coralline algae or not. Seeded my tank with live rock about 3 weeks ago.

I believe that is not coraline. It is a sign that your tank is starting the cycle though!

 

[seanocode]

So that's not good right? I've been running this system since March. Went through the cycle, then diatoms . That's about where I'm at.
Nitrates 10ppm.
Alk 6-7 dkh
Ph 8.0

Kinda looks like green coralline, not to worry. If you can't wipe it off with your finger, and its hard, its coralline. Do you have a clean up crew in there?

 

[seanocode]

A small one.
10 hermits
8 ceriths
2 turbos
6 nas
1 emerald

Looks good to me! I thought your tank was only setup for 3 weeks that's why I mentioned it starting the cycle.

Cool, sorry for the misunderstanding.

Trates are a little high and alk is low shoot for 9-12 on the alk and .05 or less on trates

I read on here about baking baking soda for an hour in the oven to dose for Alk, also raising ph temporarily.
So I started that last week, only dosed twice, but Alk is raising slowly.

I use the BRS two part

 

[seanocode]

Manually or automated?

 

[tigerdragon]

I have mine automated through my apex using brs dosers.

I was under the Impression that coralline algae Is always purple??

Can It be other colours as well?

 

[tigerdragon]

There is a couple others i believe there is a red also

 

[tigerdragon]

The colors of these algae are most typically pink, or some other shade of red, but other species can be purple, yellow, blue, white or gray-green.

Ok cheers, lear something new every day

So is this one in the photos hard, can it be rubbed off?

 

[tigerdragon]

I dont believe the green is coraline what is your phosphates?

 

[clownfitch]

The green on your rocks is a natural part of the rock curing cycle. It will start getting replaced with coralline which can also be a green color.

 

[SantaMonica]

It is algae coating the surface.

 

[seanocode]

Yeah it's got a soft or slime feel to it. I have noticed some purple color showing up as well, it does have a hard rock feel to it.
