algae identification

Hi, I’ve recently noticed this type of algae growing on my rock work and sand bed but I’m having issues identifying it. I has am appearance of bryopsis however looking under the microscope it doesn’t appear to look like it, I’ve also ruled out green hair algae as I have dealt with it before and...

Can anyone ID this algae/plant ? Crab and snails don’t touch it… just wondering if it’s safe for the tank?

Anybody know what type algae this? And this ok to be growing on scrubber?

Hey guys any help here with some ID. I’ve looked at so many posts and haven’t seen something that looks like this… not sure what to do, my nitrates haven’t gotten over 13 and my phos has always been around .02-0.06 but it just keeps growing…it seems like it grow back over night I’ll brush a rock...

I am month 4 from setting up. Started with new sand and 1/2 new dry rock Other rock was from my previous build and was just in a brute with circulating water. This algae just started to show up. Cleaner crew consist of about: 10 hermits 3 fighting conch 6 nerite snails AWC 2 gallon a day

Today an algae bloom appeared in my coral quarantine tank. This is my first batch of coral frags and my first time setting up a quarantine for coral. The frags and tank have been setup for about a week. I used Biospira to seed the tank and used a fresh mix of saltwater to setup the tank. I'm...

Any thoughts on what these spots are? I'm guessing Lobophora. This is my first tank and my first run in with algae. I noticed the brown/tan spots/discoloration first. But tonight I noticed the black spots for the first time. I'm thinking it's lobo that hitchhiked in with my emerald crab. I also...

I have this greens algae, plucks off easy, doesn’t like direct peroxide. Purple urchin slowly eats it. I have GFO running 0.17 nitrate 0.002 nitrites 0.01 phosphates calcium 400 magnesium 1380 alkalinity 8.2 pH 8.1 and salinity 33 ppt I want to get rid of it as it’s outcompeting my coral frags...

Hey all, I've got a 25 lagoon thats been running for bout 6 weeks now. 2 small clowns, 1 royal gramma, cleaner shrimp, 6 snails 2 hermits. Can someone diagnose whats all over my glass and substrate? It's not bothering the zoas but my gsp isn't opening at all and my golden glove polyp isnt too...

Mods please delete this post, wrong forum.

This is a total victory, it looks like the Carolina algae began not only to grow, but also to reproduce on the acrylic shelf. It's them, isn't it? So far, it is scratched quite easily with my fingernails. I'm happy about that, because I think it's a good sign that I've achieved good water quality.

My tank is being overrun by some brown crud and I am uncertain if it is dinos or cyano of some type. I saw quite a few people posting microscope pictures so I obtaned one and tried capturing a few pictures with it. However while I see lots of cool stuff and many little critters moving around I...

I have had this tank for over a year and a half. I recently changed the aqua scape with Marco rock around two weeks ago. I went on vacation for 5 days and it was white before vacation and now it’s filled with some sort of algae. I had hair algae in the past, so I assume it’s partly this. But...

Went away for a week and came home to this completely taking over my sump. Protein skimmer working very hard. Used up half my reef mat in 3 days. It feels very slimy and comes apart quite easily. The consistency almost feels like slime around a piece of string, but the second you touch it, it...

For about two weeks now I've been struggling with what I believe to be some kind of green hair algae. It's not terribly long and is very difficult to remove manually. My turbo snail has been eating some, but it just grows right back. My tank has been running for 2 months. My nitrates are sitting...

I have an algae appear that I need help w ID. It grows in a stringy reddish brown growth pattern. Also it may or may not have air bubbles within the algae . It may be clinging to it from my HOB SKIMMER. My tank is 2 years old. Thx

What’s up everybody, just have a quick question. I am battling some sort of algae on my sand bed and have been for a couple of weeks now. They are like thousands of little individual balls of green algae, and I can’t find anywhere on what they might be. There is a ton of them and I do not know...

Is this a sort of algae or anything else? It is taking over my whole tank.

Hello, I've went fallow on my tank for a couple months due to a velvet outbreak. During this time I started to get some GHA throughout the tank and it slowly turned into this webby reddish algae. I was thinking about getting some fish soon since the velvet is more than eradicated by now, but I...

So ive noticed this algae popping up in my tank over the past few weeks. It is on the sandbed and rocks and I have looked it up and have not been able to identify it. It is almost fuzzy little balls that coat the surface of my sand and rocks. It definitely doesn’t appear to be one of the...

Hello I have this moss like purple algae growing on my life rock. It doesn't come off like the cyanobacteria I have in my other tank, that grows on the sand and other decor. Is this also cyanobacteria or is it something else? Also I think the dark spot is good algae? I've had this tank running...

Hello! We have some hairy brown algae coming and going (snail and shrimp cuc) in the ugly phase about 2.5 months old 65-gallon dry rock bare bottom tank, (BioSpira, copepods, adding eco pods soon, showing a few tiny early signs of coralline from seeding). To the best of my recollection, these...
