algae id

Over the last few weeks, I have seen a new algae outbreak and I’ve been unable to properly ID it. It seems to be encrusting and does not come off with a tooth brush. My CuC doesn’t eat it. My LFS suggested a pinchushion urchin, but I’m wondering if there’s an alternative. I don’t want the...

Hello, just got back from a weeks vacation and came back to this. I have no idea what the dark spots on the sand bed are. Also, the slime-looking algae on the rocks. This tanks is coming up on 3 months old and I have done water changes biweekly now since the tank was cycled. Is this just a bad...

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...

Hello all just wondering what kind of algae this is and if it’s bad. I have an AIO and it’s only in the back compartment where it’s dark.

I apologize about the bad quality photos but this is as good as I could get with where it’s located sadly but can anyone tell me what this is? I saw it starting to grow about 2 weeks ago and I’m new to the hobby so I’m not entirely sure if it’s aiptaisa or if it’s another coral growing on that...

I'm not sure what this algae is, it grows like crazy and very fast. I thought it was cyno so I bought some chemiclean and put that in the water and followed the instructions on the box. it looked great afterwards, nice white sand, but its back but it doesn't look like it used to. it looked...

So I got excited because this started out with kinda a deep redial purple. I got excited and people told me on a different site it was the start of the coralline algae. Well found out the pros are here… so could you help me out? It’s stringy and now there are bubbles forming in the algae...

Hello! New here and new to the hobby. We have a 33g Cube that’s been set up since January. We successfully housed 2 clowns and 3 hermits since March. At the beginning of May, we added a Pajama Cardinal, Sexy Shrimp and carpet anem. Last week, we went out of town and did a water change...

Been dealing with this algae for a little bit now and it's just getting out of hand. Starting to grow on coral skeletons even with scrubbing and removing it regularly. Can someone tell me what this is? Having a hard time 100% IDing it. It is some sort of green sheet algae that grows in layers...

Pretty new to this hobby and I have some algae growing in my QT. Hoping I could get an ID on it and how to fix. Ammonia is 0, Nitrite is 0, Nitrate is 10. Tank is a 30g bio cube.

Any idea? The service team that was maintaining my tank just kept burying it in my sand bed. After a month it came back with a vengeance. It covered pretty much all of the sand and crawled up the rock work.

Hi all, Can you ID this algae for me. It kind of has some roots too. Came on a side of a coral and actually likes it in my tank but unsure if it will be any harm to let it grow Thanks

Looking for some help and advice identifying an algae that seems to be popping up throughout my tank. I recently had what I am almost certain to have been cyano bacteria, appeared like a red/purple carpet over sand and some rocks and easily brushed away, and I had dinoflagellates. I believe...

So I have been running this tank for around 2 weeks now (with fish) four weeks without. 2 weeks after I added the fish I noticed this lighter purple algae (I think it's cyano). It would be great to have an ID on this algae/bacteria (aswell as a few other potential pests). I found it odd as this...

I'm not sure if this is bryopsis, green hair algae, or some other kind of green turf algae. It's slowly taking over my tank no matter how much I peal off. I've tried, snails, urchins, crabs, hair algae, fluco treatment. I have a algae scrubber running growing nicely and a giant skimmer...
