algae

Recently started with this algae on my glass. It began as a thin, dust like covering but has since also developed this lightening strike like pattern. Tank is a year old and has been completely stable, with nothing added since some gsp back in March. My parameters were n03: 10 and p04: 0.01 but...

Hello there, just as a small preface I have been in the hobby for about 5 years and now am coming back from a break. I have an 80 litre nano that is now 2 months old. Nutrients were a problem because they were super low super fast. I did use exclusively live rock and a little bit of live sand to...

Can someone help ID this algae for me. I had both my conch and one snail die. I am thinking dinos but I am not sure.

Hi, A soft algae-like something has appeared in my coral tank since yesterday.:eek: (mov. 1) I'm afraid that it might be dinos. :confused: I took the piece of it and poured oxydol on it, but its color did not change. (mov. 2) I've heard If it's dinos, it turns purple. Is it unlikely that...

Hi everyone, Super newbie here with my first post, so please don’t savage me too badly. I have a 2 gallon “pico” tank which is actually a former jellyfish tank. Jellyfish were actually my first saltwater animals. Decided to experiment with an empty tank and so here I am. It’s been up and...

Can anyone ID this yellowish/brownish things growing on the LR? A short backstory, family and I went thru hurricane Michael and I lost everything in this tank (29 biocube). After the power was restored and the shops were back open I reset up tank. It’s been running for about a year before I...

What is this that is taking over my tank!? These are the best pictures I could get with my son’s microscope. But I figure someone out there might be able to I.D. what it is…. At first I thought dinos or diatoms because they came back worse when I cleaned them and did water changes. After...

So my Trachy got stressed during a move and punctured it’s tissues with its skeleton and now algae has started to grow on it and it won’t fully inflate. Any tips?

I was wondering if anybody has suggestions for cyano treatments which don't require water changes. I was thinking of using chemiclean or cyanorx but I'm not bothered to do a water change, my nutrients are also undetectable. I also don't mind waiting a few weeks or months for a product to work...

Hi community this is my first post here and I have been battling against an algae that I think is diatoms but some times it look different and I want your input, I already did a blackout but the algae come back.

Hi guys, I'm still new to this hobby. Lately I have seen some green(?) algae on top of my GSP mat. Im not sure if its green or brown cause with the blue lights I see brown spots on the mat whereas in white lights its green. Im not sure what it is so a help in ID would be appreciated. I...

This white film on the cord of my uv sterilizer and other cords in my fish tank, what is it? I'd assume it to be algae. I've had this in freshwater tanks before, I believe. It comes off very easily and feels slimy. Just want to know what it is, is it good or bad, and how to minimize it or get...

Hello I have this brown string algae all over my GSP causing it to stay closed. I don’t see it elsewhere in my tank, only by my GSP. Does anyone know what this is? I assume it’s a brown hair algae but I’m not sure. Is there a way to get rid of it? I tried basting and brushing but it has t...

Ive got a 20gal nano that’s been up for about 7 months and I’ve been experiencing a brown hair algae problem. My nitrates are 0 and my phosphate it’s 0.25 so i am currently trying to increase the nitrate to about 5 over two weeks. Any other opinions would be much appreciated!

Hello just messaging from the Arizona area, looking for some input. I’m fairly new to the world of saltwater aquarium care and could really use some advise. We have a 29 gallon tank about 3 months old housing two ocellaris clowns and a beautiful bunch of mushroom corals who have been doing...

I’ve noticed it growing for about 2 weeks thinking it was diatoms but now i’m getting more worried it’s not? any id or tips would be greatly appreciated!

This stuff started as a small patch, but is starting to get rather large and I don’t know how to get rid of it. Any idea what it is, I thought Pink Cotton Algae but it doesn’t branch or puff out into balls rather just encrust , well anything it wants to… it’s odd as I havnt introduced and fish...

My 4-month-old tank has been thru various phases of the uglies that have been relatively mild, but I see a new growth that I'm having a hard time identifying. As shown in the photo, these white fuzzy stalks are attached to rocks (or the back wall) -- the one pictured is about 3 mm tall, others...

I posted a few days ago and didn’t get any helpful responses. Can someone please help me identify this algae? I scrubbed my tank and did a water change Friday evening and now it has all just come back so quickly. Is this GHA or bryopsis? Or is it something else by chance? I want to...

Hi guys - For the recent few months this red algae / bacteria has been excessively growing on my sand and every time i attempt to remove it with a gravel cleaner, it grows back within a week or so. Can anyone please help ID it and if it is my nitrates what is the most effective way of lowering...
