What kind of algae is this?

What algae is this?

Hi everyone! Could I get an algae ID on these specimens I pulled out of my system? TIA!

Hey everyone does anyone have an idea what this algae is? Is very easy to pull off the rocks, but it also forms in balls on the sand. Don’t have any idea what it is and it just showed up about a month ago. If someone knows what it is, what is my best solution to fix it? It looks reddish...

Hi Guys have had this outbreak and been trying to get rid of this algae for 2 months. I have tried 50% water changes Reef Dynamics Vibrant Any advice or solutions anyone can offer. I added a video. Thanks

Hi all, I have been battling with nuisance algae for about 2 months now. I noticed it start to build up when I started to dose Red Sea Reef Energy Plus. I stopped dosing Red Sea Reef Energy Plus and began to dose Microbacter clean. I am on about 2 weeks of dosing MB clean. The past 3 days I...

I have this dark brown/black algae? On my rocks. I’m pretty sure it came in my system from a fragpl plug. It is encrusting and doesn’t come off easily when scraping. It does feel a bit soft to the touch but it doesn’t seems to be a sponge as it is not plump or does have any holes or intake on...

Hey everyone Ive been struggling to figure out what is growing on my live rock. I have a 150 gallon FOWLR with a 60-gallon sump that I've had for 2 years. I have a long spine porcupine puffer, red coris wrasse, harlequin Rusk, majestic angel, 5 lyretail anthias and a snowflake eel. My parameters...

I’m growing monti on the back glass and the algae had stopped it from continuing so I started to remove the algae directly above the monti. If I physically remove all the algae at once on the back glass are there any negatives that could happen?

So I've had this white/brown slime stuff for over a year now. It started as a thin layer of almost slightly fuzzy white slime on the highest rock surface in my tank. Didn't seem much to worry about at the time. It got worse over time, and for the year this stuff has been covering every single...

So I got a microscope because I have been dealing with what seems to be Dino’s on my sand bed. In the video there are these things racing around SUPER fast. Are those dino? If so. What kind?

Hello I have an 250 gallon fowler aquarium it's been up and running for about 6 years well this tank is a year old but the rock and fish were transferred from my last system of 5 years.. this started as a small dime patch a quickly spread. I did add an aqua uv 57 and started to lower my...

Alright boys let’s play a guessing game. I have some pictures and I’m wonder what you all think. I have a microscope coming tomorrow to confirm. DINOS? DIATOMS!?

Hello, I need someone's input. Been reef keeping a while now. But this is the first time I encountered this algae. The tank is a 155g shallow including the sump. It'sbeen up for about 2 months now. I know that diatoms are a thing for new tanks but this is the first time I saw this. it looks like...

So i have this algae that appears slimy on my rocks and kind of comes off in sheets. I was worried it was dinos but doesn't look like that. Under the microscope I see this: Can someone confirm whether or not this is some form of filamentous green hair algae? Just seems super small to be that

Hello everyone! Fighting my first Algae Bloom: Almost no visibility within the tank. Is this harmful to the critters? I was told blacklight can damage certain animals but was unsure. I replaced about 10 gallons of water today and did a 50% change yesterday. Was hoping one of these would...

It grows in small circular spots like this and is hard to scrape off. Only a razor works.

Tank is about 5 months old. Nitrates and ammonia are slightly high but nothing crazy. Are these Dino’s? It did get worse after a water change. My nem seems not to like it very much. What do I do?

I’m not too sure what this is but it’s hard to get rid of. My initial thought was that it’s cyano but after 2 doses of chemiclean it seems to just be getting worse. My nitrates are .02-.05 and phosphates are at .006-.008. If anyone knows what this is and how I could keep it at bay I would...

Hello all. I've been in the process of stocking my tank in the past month or so and had a question. I have a number of different macroalgae in my display and have noticed some accumulation of nuisance algae on their surfaces. My current cleanup crew (Tiger Conch, Trochus/Nassarius snails...

Hello. I've been suffering from excessive algae growth on the glass for about 2 months. I'm not talking about normal green film algae that needs scraping every few days, but I'm getting this strange green "dust-like" algae on my glass that starts to come back 5 minutes after wiping! No...

So I got a new sump after my all in one tank broke (the black plastic part that divides the tank itself and the filtration to the back) nice eshopp nano sump… and I decided to put some chaeto to bring down my nitra, and phos down since they were high .70 and I got a kessil H380 halo algae grow...

Happy Saturday reefers I have a light purple branch algae that hitchhiked on my Feather Duster tube. I read somewhere that Feather Dusters don't like algae on their tubes however, something tells me this algae isn't harmful and perhaps even beneficial. Can anyone shed some light and/or ID? Any...

Following hurricane Helene our 200 gallon Red Sea Reefer XXL 750 has been a disaster. Our tangs died and with that came an insane amount of algae, cyano, etc. (and neglect, given everything). On the plus side, my pest paly’s have been beaten back. I’ve got some healthy planted mushrooms, zoas...

Does anyone know what kinda algae this is? And what I gotta do to get rid of it
