cyano

I keep getting cyano over the rocks and gravel of my softie tank and I’m trying to find the cause of it. I’ve tried running dr Tim’s re fresh and waste away and it comes back within a few days. I’ve added bacteria. I’m just looking for input on what I should do. I have about a year old 20 long...

Does anyone have an idea what this could be? I have had them pop up on the past and I thought it was Dino’s, but it disappeared for a while and now has made its way back, but now more than ever. Should I dose vibrant? Thank you!

Bubble algae issue is getting way out of hand, I’ve got 6 emerald crabs in a 50 g display (90g system) and they haven’t made a dent. Manual removal isn’t really an option most of the rock work is covered in coral or fused together with putty making it way too large to pull out. I try to scrape...

Hey guys newb here, It’s only at the base of my Duncan and nowhere else and where it’s missing tissue. More visible under all blues, doesn’t blow off but scrapes off easily. Wanted an expert/pro opinion maybe @vetteguy53081 could offer some insight before I proceed with the h202 dip/ toothbrush...

Is this dark purple stuff Cyano or Coralline? It’s not hairy and doesn’t come off when I scrape it with my finger nail. My tank is over 2 years old and this stuff doesn’t look like my lighter colored coralline. I’ve never dealt with Cyano so I’m kind of panicking. It’s on some of my live rocks...

For years I had red cyano that would come and go in small patches. I never paid attention to it. Recently, I have seen this green stuff partially beat out the red for space and I am not sure why. It may have come in on a new frag. Anyways it looks green under the whites but under windex it turns...

Hi all, hopefully you can help me!! I have a 24 gallon AIO waterbox peninsula, roughly 8 months old. I have been battling algae for the last 4-5 months. I believe its a combination of diatom, dinos and maybe cyano? the algae doesn’t completely disappear at night, but does reduce slightly. If...

Hi all, I suffered a prorocentrum bout a few months back and it has come and gone in a few patches since, but now I noticed this red stringy stuff that eerily looks like an increase in Dino. I put it under a microscope but I couldn’t really identify anything. I attached a video! #reefsquad

Tank is over four years old. 40 Breeder with HOB skimmer and refugium with Chaeto that I harvest weekly. I do a weekly 5 gallon water change including some sand vacuuming. For about the past month my sand has been growing this brown substance on it. It goes away at night and gradually comes back...

I don’t know what else I can do! I’ve been struggling with this type of algae (or cyano idk what is this) for some months. I did several water changes in order to stop the development. I spend my weeks quiting the algae of the tank and scrubbing the rocks, idk what else I can do.

Hello kind and helpful reefers! I have what hopefully is an easy question. Took a sample of my substrate as I have been having issues with a brown coating on my aquarium that forms once lights go on and go away when they go off. This has been going on for over a month. I don't believe it's...

1.Is the first picture is of aiptasia or feather duster? 2. I am seeing brown/reddish film like layer on few few sand areas and also on the GSP. Is this cyano?

I’ve got some microscope pictures! I have a Cyanobacteria outbreak, it’s starting to grow over some corals. I used chemiclean 2 weeks ago, did the 20% water change after and have continued with my weekly 10% maintenance changes. The cyano came back way worse, I’ve also been dosing vibrant. I see...

It doesn’t look like cyano, it doesn’t come off when i rub it vigorously it feels kind of soft like a sponge.

Hey guys, noticed a few dark purple spots on one of my rocks, could somebody help identify if it is Cyano or possibly coraline? thankyou

Hi all, Long time reefer and big time user of Reef Aquarium Guide forums back in the day. Once I started college my mom sold all my tanks and I’ve only now just gotten back into the hobby. Anyway, started my first tank since 2008 back in January and everything was going fine until I moved and...

Anyone dose af life source on a weekly basis? Heard it’s good for cyano and bio diversity… Cheers

Picked this up on sale. I have some of what I think is cyano or red slime, hoping to get rid of it. Anyone familiar with this product? Any tips?

Hi Had diatoms a while back and they went on there own….. Then cyano came which I’ve been battling for around a month ish….. I used chemi clean first does 24 hours second dose 72 hours….. 99 % of it went just had a very small light pink patch size of a penny…. That was 3 weeks ago when I used...

Ok so my parameters are as follows…. Salinity 1.023 Alk 9.34 Cal 466 Phos .09 Ni 5 and I know that’s a little high Mag 1383 I just performed a 25% water change and added cheato two days ago but the brown dust is back, which I’m pretty sure is detritus? I have done 25% water changes and just...

is this cyano? Trying to figure out what kind of algae is growing all over my tank, and what I can do about it. It’s green slimy stuff that has air bubbles grow up out of it over the course of the day. Recently moved, taking my tank 7 hours on a trip in buckets, and was wondering if the upset of...

Hi treating cyano with chemiclean….. nearly all gone just doing a second dose….. I have a in tank tunzee skimmer and have took the cup off to help put O2 back in the tank…… This is putting a large amount of micro bubbles inside my tank, will this harm my fish? No corals at the min… Thanks in advance

Recently I’ve noticed this reddish looking algae just in this frag rack and on my glass and was wondering if this is cyano?

I am having an issue with my tank. I’m struggling with cyano. My tank is a 25 gallon AIO with a Tunze 9001 skimmer, filter floss, and chemi pure blue. My phos is currently 0.11 and my nitrate is 0.0. These parameters have been largely the same regardless of water changes. I’m currently up to a 5...

Are these diatoms still or could they be something different, or are diatoms dying and reforming? I'm confused. I'm at about.the 1 month, 1 week mark since putting biospira and first fish in. Some of this algae is Dark brown, some very light brown. Some rust colored (a yellowish rust) like...
