cyanobacteria

So this has been growing in my tank for about 4 months now, a deep green film, especially in areas of high light. It grows on the rocks, and the glass but never touches the sand. It also covers right over any corals on the rocks, it killed my bird's nest coral in a matter of weeks after getting...

Hi All, Been struggling with this for months now and nothing seems to fix it. As per the photos it looks like Cyano, however I have done two lots of Dr Tims 2 week programs. Dropped the skimmer back to not run all the time. It will buld up in the sandbed first and then slowly it will grow on...

So this has been growing in my tank for about a month now, deep green patches, not really hairy or overly slimy, it grows only on the rocks, and it grows in expanding circles like green coralline algae does, except this is a much deeper green than coralline (I've had some of that as well), and...

Hello to all and Happy Holidays! Currently having an issue with a clear film over most of the LR (can't tell if it's bacterial or an algae) and a small Cyano bloom. Tested water and got some conflicting results. What should I do? 11 month old 30 Gallon DT Drilled 10 Gallon Baffled Sump W/...

Hello my 50 gallon aquarium is still under a year old and I've been constantly fighting low nutrients. Even after adding more fish (6 total), I was never able to keep PO4 or NO3 stable and in desired range. Often I was bottoming out at 0. I have been dealing with cyano for about three months...

Hi everyone, So as the title says, I’ve been fighting amphidinium dinos for not exactly sure how long since I had a good amount of snails die before I really got to the root of the problem, but it’s been about 2 weeks of dosing nitrate, phosphate, and silicate along with bacteria, photo, and...

I have a new 3 mth old tank with the brown cyanobacteria all overy rocks, having to clean sludge off the glass every 2nd day. Is there anything that eats it or anything to treat it? Any knowledge much appreciated.

I've had some trouble getting even flow in my Max E 260 and I'm currently fighting a Cyano outbreak so looking for advice. Currently the bulk of the flow is coming from two Tunze 6095s at the back of the tank pointed at each other. I have them controlled by my GHL profilux to create random...

Hello, the following sponge is taking over my tank. It's literally growing over ALL my rocks and covering the base of some corals. I know it looks like cyano bacteria, but the thing underneath when trying to remove it manually is definitely a sponge like thing. I tried removing it with a...

Hey all, I don't have a microscope. Just want to know of there's a way to tell the difference between cyano and Dinos without one. The video attached is what I have in my tank currently. T

Please help identify. I’ve had this in my tank for about two years and the only thing that gets rid of it temporary is Chemiclean. Thank you for your help

I recently made a bromide addition to my aquarium and noticed that the appearance of cyanobacteria that I had in some places in the tank disappeared. Another hobbyist added bromide to his tank and also observed the same effect. 1 - Does anyone know the effect of bromide on cyanobacteria? 2 -...

Could very clear water(I think it may be very clear at least partly because of a lack of humic substances)promote the growth of cyanobacteria? https://www.researchgate.net/publication/232093034_EFFECT_OF_HUMIC_ACID_ON_SPIRULINA_PLATENISIS_PRODUCTION_AND_ANALYSIS_OF_NUTRIENT_CONTENTS

Hello, I usually don't share my videos on the Generals subcategories of the forum, most of my video are hidden in my thread you can watch here...

Hello, so despite my research there's an element I'm not understanding with: How Nitrate help Cyanobacteria? I can't understand where the bacteria need it for growth, I'm confused. To build up one of its membrane layers? To promote the thylakoid? Obviously, it depends on the strain of...

Hello everyone! So my boyfriend and I both have nano 20 gallon all in one tanks (both about a year old) and we have been running without skimmers with no issues up until now. We’ve both started to get cyano bacteria on our sand beds but our tests are showing that our water is perfectly fine! I...

Hello reef2reef community , in the diatom stage of the cycle (hit one month). bringing an old tank from the dead with cycled live rock that ran in an established tank for roughly 5 years. Did my first water change after a couple diatom spots started creeping up. Diatoms are now gone but for...

Hi Ive got a torch coral that is receding a bit from cyano and dinos and want to use the dip that will be easiest on the coral but still remove them. I have lugols solution, coralrx, and hydrogen peroxide just want to use the one easiest on it as the cyano isnt growing too fast. Most of my tank...

I have this stuff all over the sand. 5 nitrates, 0.19 phosphate. Any thoughts? Seems too heavy to effectively siphon out. Blows off the rocks and frags very easily. Goes away at night, comes back strong during the day. Orange picture has a yellow lense over the camera, bluer one does not.

Hey, I've been battling one or two of the three that I listed in the subject. Ive been trying to maintain nitrates at 2-5, and phosphate has been 0.05. I have been dosing neonitro and Microbacter7. Here's a video of the algae under the microscope:

Hey folks! So I had a minor cyano outbreak. After chatting with some folks at my LFS, I took their advice (against my better judgement) and dosed with chemiclean. I was pretty hesitant about the use of chemicals as I am generally weary of any chemical additives. Hindsight being 20/20, I...

I'm just so tired of it and feel like I'm at my whits end. It's been a long 4 month battle and I've tried next to everything except chemical, which I rather just not do. I know I've read plenty of raving review on Chemiclean and others, but many of those just have the problem come right back...

Very new to the hobby. I have a 54g display + 11g sump = 65g total water. I have two baby clowns, royal gramma, lawnmower blenny, an astrea snail, and an emerald crab. Bio load is very low. Gramma, blenny and crab were just added yesterday. For corals, I have a xenia, paly and zoa-all frags so...
