cyano bacteria

Just a thought. I currently have three saltwater tanks running. When I first started out, the tank I bought was used, and I made the mistake of using the sand and rocks from the previous owner. He did mention there was cyano, but at the time I didn’t know what it was (I know, stupid). Now, after...

I don’t know what to do anymore. I feel like I’ve tried almost everything. I have a big problem with cyano, and I can’t get it under control. I’ve tried manual removal and I’m running as much flow as possible without blasting my corals. At the moment, I’m running 10 hours of light, including a...

I have a very bad cyano problem in my tank and I’m looking for any ways to deal with it. I’ve dosed chemiclean four times, my mother and I have spent hours manually removing it for weeks, I’ve lowered my nutrients since I assumed my phosphate being high was the cause (and now my nitrates are too...

Hi all, I have 75 gallon that I made a post about about 3 months ago I was battling GHA, luckily 90% of it is gone at this point but I am now facing cyanobacteria. I think the cause of this was when fighting GHA I had really high phosphates and nitrates which I still do just little bit lowered...

I’m so close to being ready to put dwarf seahorses in my macroalgae tank… the dinos are gone, the nutrients are stable, the macros are grown out, and the tank is pest free… except for the cyanobacteria. I know that chemiclean would get rid of it, but I’m worried that there may be repercussions...

I’ve been running this 15-gallon macroalgae tank with a pair of clownfish for about 7 months now. I do 15–20% water changes every week and feed carefully. Despite that, a slimy film has started covering all my macroalgae, the sandbed, and the rocks. I’m running activated carbon and Biofil by...

I'll preface this by apologizing for the long post, but I'm all out of ideas and my parameters don't tell the story happening in my tank right now, so a lengthy backstory is the only info I have. ICP results are below, but basicly corals started RTN/STN slowly wasting away along with red cyano...

So I have a display refugium plumbed into my main display. In the refugium I have some what I believe is cyano starting to grow. How can I combat this in a refugium without damaging the ornamental macro algae? Nitrate is 8-10ppm Phosphate is 0 - 0.03ppm I’ll attach some photos of the what I...

I haven't done an update on my 125 gallon tank in a long time, but now I need help for my tank. By accident I added tap water from my sink and as a result I have a massive outbreak of hair algae and cyanobacteria. I treated the tank before with chemi clean and not only did the cyanobacteria...

SIGHING OUT LOUD. So, I think im having an issue. I think its my circulation problem, but I'm not 100% sure. There is one section in mg tank that i don't think is getting flow, but i have no idea how I'm going to get flow in that area because my sand starts to move around way too much. This is...

First I delt with dinoflagellates, now I'm seeing cyanobacteria of the red kind pop up. What are the best ways to deal with cyanobacteria?

Hi, I am sure this has been asked multiple times before, but I am new to the hobby and found different answers in my internet search. Is this Dinoflagellates, Diatoms, or Cyanobacteria? How do I get rid of it? Any advice is greatly appreciated. I started this tank in March and started having...

Hello! I hope someone in the community may be able to answer my question. I have had my ten gallon tall reef tank running for about 1 year and two months and it has most definitely been a learning experience (a good one :)). For the entirety of my tanks existence, I have used the Top Fin®...

Looking for some advice regarding my lighting set up on my Fluval Evo 13.5G. I upgraded the standard LED lighting to the Fluval Marine 3.0 22watt Bluetooth lighting. Started suffering with Cyano, even though my Nitrate & Phosphate levels are not bad. I think it might be my lighting that is...

I have a lot of purple cyanobacteria on my sand and I just did a treatment of chemiclean and nothing changed! It has been 78hrs and I just did a 35% water change. Should I do another round of chemiclean or what else is there to get rid of it Ps: 12 week old tank 2 ocellaris clownfish 1 sand...

Can anyone tell me what I’m looking at under microscope. It’s kind of reddish so I was thinking cyano. But there are bubbles on it too. I did positively ID a tiny portion of Dino’s in the video. But what’s the other 90%?

Hi I am struggling to get rid of my cyano. Following twillard’s thread I starting dosing 3% hydrogen peroxide on 10.12.23 at 1ml per 10g (16 ml for my 160 gal). This was making no impact so upped it to 30ml on the 20th. Today there is still little impact. Some matts are lifting up but soon get...

I wanted to post this for anyone battling cyanobacteria. I had been doing weekly water changes for months and nothing was working trying to wipe out cyanobacteria. I was even considering Chemiclean. One week i forgot to do a water change and noticed it started to clear up. I decided to switch to...

Can anyone tell me what this is. It looks orange under blue light. It peals off almost like a thin piece of paper or skin. It has clear bubbles mostly on top but some seem to be under it. Could it be Cyano? It’s definitely not bubble algae. I did have a problem with no nitrate and kinda high...

I was wondering about this and never seen a thread that adressed this issue. If i get a frag from a tank that is known to have cyano ou dyno issues, are they going to be transfered to my tank?

My reef tank has been setup for 9 months and Im still battling this horrible red algae. No matter how much I remove it just keeps coming back. My tuxedo urchin ate so much at first but not any more. The algae has wiped out 2 zoanthid colonies, covering them up in this red slime and wiping them...

Hi All, I noticed this morning a very small patch of what I am guessing is a type of algae or cyano that is a vibrant orange under my blue lights. I just finished a round of chemi-clean early last week (~9 days ago) to wipe of the regular maroon colored cyano. The treatment worked as all of...

Hi! All of my Banded Trochus Snail seem to be suffering from paralysis. They have all fallen off the glass to the floor. Their foot shows that they are alive, but they seem to lack the enegy to attach back to glass and just lie there slowly diying/starving. I have pulled them all out of the...

Tank: 10 gallon AIO TL;DR neglected tank, what’s the best way to clean up so my pump quit working while I was out of town, took a while to notice, order new pump, install, etc. in the mean time, I’ve developed some hair algae, algae growth on the glass, and all kinds of algae along the glass of...
