algae

This 15 gallon nano is 2 months old. I only had a pair of clowns for a little over a month and then I put in my Duncan and pipe organ because they looked unhappy in my other tank. The coral actually started improving surprisingly to me and all was seemingly well until last night. Last night, the...

Hello, I started in this hobby over a year and a half ago and this site along with many others have helped me navigate the reef tank world for all this time with major success and the occasional incident. Finally, I made an account days ago and was going to post a fun thread introducing myself...

Is this dynos or something else I cleaned the sand bed and the rocks from a huge agar bloom and now it’s doing this a few days later I’m getting a uv sterilizer in two days and I’m trying to get rid of it for my nem tank?

I keep second guessing myself. Thank you all very much for sharing your knowledge.

For the last month or two I’ve been having a constant battle with brown hair algae. I’ve reduced feedings, kept lights on for only 4-5 hours, dosed my supplements only 2-3 times a week (before I did it once every day) and picked as much as I can every water change but still, it’ll pop up after...

What is this? How do I fix? The gsp has not fully opened since I got it a few weeks ago.

Hi all - I have this purple-reddish algae covering all my rocks and filter equipment. I have read about cyanobacteria and coralline algae, but this algae does not seem to match either description. It spreads fast on rocks and hard surfaces but seems to stay away from my crushed coral substrate...

Hey can anyone ID this? I pretty sure one is GHA but not sure if the other is bryopsis or something else.

I have a new tank, around 3 months old with a handful of corals and 2 Clownfish. Within the last few weeks my Nitrates and Phosphates have both dropped to 0 (using Hanna checkers for both). These Dinos started showing up recently as well. I've been dosing NeoNitro and NeoPhos trying to get my...

is this Dinos or diatoms? It smothers my corals and comes back everyday.

Have a few clove polyps with this weird slime growing on them, had some back and fourth with a local seller saying its algae but i kight think its brown slime, need some help to identify it amd what i can do to remove it (if the photo isent clear its a lil green btw)

Having a hard time identifying what this is growing on my rock scape? Possible bubble algae? Any insight would be great.

Hello! Was curious if this was bubble algae that came with my Frogspawn frag I got today? If so, what’s the best way to get rid of it? If not then what could it be? The bubble like substance by my thumb. Dark in color. I didn’t dip my coral so maybe this was my first mistake..

Hi all, over the last couple days ive had this werid white algae form. its slimy to the touch and easy wipes off. My water peramiters are all within the good zones apart from a nitrite spike. it was zero now its around 2 - 4ppm it fluctuates over the last week. My bimedia just wasnt enough so...

I just cleaned a bunch of algae out of my sump and found these critters that look like tiny smooth (no hair or bristles that I can see) caterpillars. I’ve never seen these. In the photos they look flat, but they aren’t. They are nice and chunky. Any help on an ID is appreciated!

Hello everyone, I will be moving soon and because of that I am tearing my tank down and selling it. I filled up the 25 gallons of my tank with 1 pound of citric acid powder. All my rock and corals and fish were out obviously. I left water and algae to be killed my the acid. After about 24...

Id please

I've been battling algae back and forth since I set my tank up last December. It'll get really bad and then clear up really well for a few weeks and then come back. I'm curious what it is I'm fighting against and was hoping to get some help with ID'ing it. It gets really bad in the sand, I'll...

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...

Hi all, I’m having this type of algae growing all over my tank, majority of it is growing on the sand bed. It doesn’t look like green hair algae to me, this stuff feels more rough..Please help!

Hi Guys, Can anyone help ID the algae issue I’m having. I managed to get a video under a microscope, not the best of quality unfortunately. I’m thinking this is dinos and cyano but I’m not 100% sure. Thanks

For a little bit ive had this brownish red algae that has just covered my tank and some corals. Im very unhappy with the way my tank is right now and im unsure of what to do. I feel like ive tried everything so far for nothing to work. Below are pictures in normal light and white light. Ive cut...

Sorry for the noob question. Found this Algae growing on my rock when I came back from a trip. Is this green hair algae? Feels darker than that and under blue light it looks a bit more dark brownish red? The video I filmed under "Feed mode" on my Hydra 32s which is more of a white light. Thanks...

This algae been growing on my rock and back of the aquarium for the past couple month… it killed a lot of my zoas and mushrooms by covering it. I just don’t know what to do. I use chemi-clean couple month prior… I don’t know if that’s the reason why I got an outbreak like this. I don’t even know...

What’s an easy way to get this semi caked on algae off the glass? I’ve been slacking on taking the magnet to the tank. Any suggestions to get this cleaned and looking better. Obviously don’t want to scratch the tank
