algae id

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.

Hey Reef Gang, I am new to the salt water game coming from freshwater. I am starting with a Red Sea Max Nano. 20lb Carib sea life rock, 10 pounds Fiji pink, 660gph wave maker, running skimmer 24/7 with filter sock, bunch of marine pure bio balls, red sea carbon, Red Sea coral salt pro, tank...

Can anybody help. New to here and tank around 9 months old. Had an algae outbreak. Not the best pics but starting to stand up with air bubbles on the tips. More brown/orange under whites. Goes away over night nearly completely and then back when lights on. Running 5 hours blue and 2 hours white...

Salinity 1.026 Nitrate 0 Phosphate bounces from 0 to < .02 PH 8.2 Alk 10 Calcium 440 Mag 1500 I use RODI water, 0 TDS. Tank Age: 6 Months. So this stuff has been in my substrate for awhile now, it was brown, but now is green. Substrate gets plenty of flow. I've had to adjust it a few times to...

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...

Current System: Biocube 32 Steves Turbo LED Upgrade Intank Meda Tray with Carbon Coralife Protein Skimmer Salinity: 1.026 Ca: 480 Alk: 8.9 Mg: 1500 NO2: 0 ppm NO3: 0 ppm Ammonia: 0 ppm (Phosphate test kit ordered) So I've had this algae start to spread over the past 2 weeks. Initially I tried...

Can someone help me id this algae? It's not hurting any corals. Nitrates are at 0.5. And also how to do i get rid of it? Should i just take it off with my hands?

Have been quickly growing this algae, at first I thought Dino’s but know I’m not sure, one thought is Lyngbya Cyano. The tank is 2 months old. Tank is IM 20 Upgraded IM pump (500gph) Aqamai KPS (running 50%) 2 Prime HD Ghost skimmer Refugium in 2nd chamber Chaeto +pods 2 intank baskets running...

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...

I have this very fine, fuzzy-like stuff that covers the frag plugs in my coral QT...it is also on the 2 live rocks that i have in that tank as well. In the pic, I can see a few air bubbles. I've been battling diatoms regularly in this tank, but those are receding quite a bit. I can't keep...

In addition to some scattered sections of GHA my year old mixed tank has these weird stalks of algae. Looks like bryopsis but without the feathery bits. Possibly young bryopsis? The hair algae is much more fine than this stuff. Ideas? I apologize for the image quality. Had to enlarge the...

Attached is a YouTube video of a couple different types of algae that is currently in my DT that is about 4-5 months post-cycle. Help identifying would be appreciated... 1. I have some easily identifiable GHA in my refugium that I keep cleaning out. But, the video shows another brownish...

Good morning Reefers! Can anyone tell me what type of algae is growing on what I think is my Pink Branching Cyphastera? How could I remove it if needed? Thanks in advance!!

This is the best picture I can get -- these are thin, brittle but hard shelves growing out primarily from this location. I have some LR near it that has some established blue coralline (can't get a good picture that isn't washed out from the whites). Please bear with my poor picture...

What is this stuff and how do I get rid of it? Will this kill my corals? I have RODI water and have been doing water changes. I am so worried it will take over and kill everything.

Since we don't have particular group for ID-ing algae, I'm going to post it here. Have you guys have this sort of green algae in your live rocks? It's not slimy, no hair, almost like encrusting and apparently is different morphological form of Coralline Algae. It's definitely unsightly in...

Hey everyone, I got a new frag and some type of algae has started sprouting out of it. I couldn't identify it by the spouts as most pictures I search are full blooms. Can anyone tell me what this is?
