Cyano, Dino or something else?

For a time there I thought Dino, but after more reading on the symptoms and pictures, I have my doubts, I read on a link here that Cyano comes in different forms and one being very stringy and hair like.

So I included a video that will show it the best, I had the lights off, but turned them on for the video.

Marine Algae - YouTube

 

Video is unavailable for me, so this is guesswork. I had a case of diatoms that looked an awful lot like Dino. It was stringy, full of bubbles, etc. if you're not running a phohate remover, try some GFO for a few days. It strips silicates as well asphohate, which should clear it up. If of, it's something else.

 

Looks like cyano and dino to me.

A give away is the closed zoanthids. Dino is toxic, I had more issue with zoanthids and dino than any other coral.

 

I'm not as familiar with dino but it looks like some is definitely cyano......unfortunately, I think the treatments are different. It would be worth a try if you're not already to run some GFO and carbon.......

 

Their open now Corailline! I had them in darkness for almost a day, before I decided to turn on some lights and take the video.

I left the light on so all is open now, will put them back in the dark though until I can figure what to do.

 

I can see the video now and I'm leaning towards light starved cyano. Wouldn't argue the point with anyone though since its hard to be sure. What is in your tank, do you dose vodka? Bio pellets?

Does it look different after the lights are on for a while?

 

The tendils "filaments" are likely indicative of dinoflagellates, although, I also see what looks like cyano too. As for toxicity, there are around 2000 species of dinos, I believe only 60 are thought to be toxic. Both dinos and cyano can coexist and often do. Allowing silica and nitrate to rise usually does them in IME, although, with so many species, it may depend on the strains. How are your parameters?

 

Ahh....an actual benefit to having nitrates

 

The lights are out, but I will check what I can right now, I get another kit tomorrow in the mail for the one I don't have
