So what is this and how do I get rid of it!!??

[mightymizz]

I thought I heard that if it is a type of lyngba, this algae has a sheath that does not let something like chemiclean work on it.

Please feel free to correct me if I am wrong.

Highland, the "algae" I have looks exactly like JG1's picture. I am sure I have this right after I upgraded from a MH light to dimmable LED. I was too excited to acclimate the light, shot a lot of blue color into the tank. I would say that is my root cause.

As a last resort imo, using an antibiotic may help for a cyano pest.


Lastduke, I believe your pest sounds more like an algae, perhasp bryopsis or some red algae, which antibiotics won't work on. Perhaps increasing mag levels may help.

Not sure what chemiclean is... generally cyanobacteria and its relatives can be dealt with using antibiotics.

 

[mightymizz]

So, how is it looking today?

Chemiclean is a type of antibiotic IIRC.

What do you guys think? I think I see some progress from yesterday.

 

[waldomas]

If you didn't siphon or brush, it looks like its receding or breaking up!

 

[JG1]

No, haven't tooth brushed it since sunday

 

[mightymizz]

Definitely looks like it is receding some.

Unless the pictures are captured differently from different angle, I see improvement. Look at the edge of the rock just right above the black hole at the top left corner. The 5/11 picture still shows long strains of cyano while the 5/12 shows almost nothing. The overall color of the rock from 5/12 is a lot lighter as well.

Think I should do lights out for a day or two just to really stick the knife through this stuffs heart? I really think the tech-m is what's killing this stuff. I just want to completely eradicate this crap, that's why I was thinking a brief period of darkness. Seems like this stuff is dieing off during the night.

 

[JG1]

Also, should I let my Mg gradually fall back to upper 1300's or should I keep it at 1600+ ?

 

[JG1]

Was looking at other rocks there were COVERED in this crap a few days ago and they look pretty clean. So glad this stuff is dieing off.

 

[dzhuo]

I would not do lights out since it's already dieing back. Are you running carbon? If you have carbon handy, I would run it just in case there are toxin released which could cause stress to corals. I would let mg stay for a few more days to be sure. After that, a couple water changes will probably naturally bring mg back down.

Looks like you are winning the battle. Nicely done!

 

[JG1]

Yup, have 3/4c of Rox .8 going in the BRS Rx. :beer:

Just exchanged it 3 days ago in anticipation of this crap dieing!

 

[dzhuo]

Be prepare for another type of algae showing up! After I get rid of mine: coralline and hair algae rapidly take its place. However, I consider both to be a lot more natural and I am actually happy to see them: They give the tank a more mature and natural look! Wouldn't you agree?

I think you are on your way!

 

[mightymizz]

I just posted in my thread that I watched some turbo snails eat away some tufts that they came across.

 

[JG1]

Oh I can't wait for the coralline to take off!!


BTW, woke up this morning....I think this stuff is 99% gone.

 

[JG1]

It's 100% gone.

I'll take a pic tomorrow.

 

[dzhuo]

Nice! Yes I think we want to see picture. You believe Tech-M is what kills it? How much do you have to use to raise Mg? Does it cost you a fortune?
