Need help identifying what this red algae is, please...

[decena]

This red algae appeared about ten days ago. It is photonsintetic. He has covered some montipora corals. What could it be?

 

[Adele]

Well could be cyano bacteria. But there is another unpopular Red Turf algae. I am not familiar with this species so perhaps another will chime in. Is it truly red? Pics look a little brownish.
What are your water parameters?

 

[Brew12]

I can't make a guess based on the photos. Too much blue light.

Thanks for your answer. It is brownish (not very red). Water parameters are:

Kh = 7.2 - 7.8
Ca = 425 - 440
Mg = 1500 (Always very high, I don't add Magnesium. I use Reef Fusion 1 and 2)
PO4 = 0.01 - 0.02
NO3 = 0.5 - 2
Temp = 26
pH = 8 - 8.2

I use zeovit system. I am using these products: Zeolite, Activated Carbon, ZeoStart, Zeofood, ZeoBak, Bio-Mate, CyanoClean, Coral Vitalizer, Coral Snow, Eisen, Coral System 1 2 3 4.

Balling: seachem reef fusion 1 and 2.

Total Volume: 80 gallons
Return flow: 1500 gallons/hour.
2x Vortech MP40QD (40%)
illumination: radion g4 pro

I hope you can help me, thanks!!

I'm sorry about the photos, I tried to make some better pictures only with white lights.

Does it ever plate out or just encrust?

 

[Brew12]

It does look like you have multiple issues going on.

I'm pretty sure some of what you have going on is a form of cyanobacteria. I can't tell if the fuzzier stuff is also a bacteria or possibly a turf algae.

It is jus encrust. It is always in the same place (two rocks and and montiporas)

Thanks a lot for your help! Could I use ChemiClean?

Of course you could!

I would try to pull some out, put it in a container, and add a little H2O2. See if the water turns red. Odds are if the water does not turn pinkish red then chemiclean won't do anything.

What do you have as far as a CuC?

Thanks! I'll do that. As CuC I have:

6x Trochus histrio
1x lysmata debelius
2x lysmata wundermani
1x trombas luhanus
1x emerald crab

Do you think is enough? (I don't use sand bed). Thanks for your help.

No, I would definitely add more. Not sure what a trombas luhanus is. I would add a few hermits if you are comfortable with it. I prefer the blue legged variety.

Looks like you got some good advice from @Brew12
I’d do that cyano test and go from there. I’ve had excellent results from chemiclean but try everything else I can before using it.
Your water parameters seem to be in good shape so the CC might be the way to go if additional CUC doesn’t help. I’ve read that the Tuxedo urchins have a taste for this stuff. Keep us posted on your progress. Always nice to see the full circle outcome on these situations.

 

[hyprc]

Just be weary how long you keep your skimmer off during the treatment if you do confirm it's cyano. Don't want those toxins floating around your system for more than a day or two once it starts dying off. The corals should tell you

Thanks Brew12. I will add a few hermits. I wanted to say "strombus luhanus", sorry.

Thanks a lot for your help @Adele. I did the cyano test, but water didn't turn red, so I didn't add chemiclean. I think it is improving, but anyway I will increase my CuC

Hi! The algae has finally disappeared. Thanks for your help @Adele @Brew12 @hyprc

Fantastic! Very glad your system cleared up!

Hi decena
I don’t know if it’s the same algae I have here in my Micro Reef Tank, but how did you solve your algae issue ?

Was it this algae ?
