algae

I am running an Eshopps 9.5 gal. bi-level nano tank. This is my first saltwater aquarium and have had running for about 1 year. I started with live rock and live sand with two clown fish. All of the corals I have glued on the top tier have died. Usually within a month or two. In the...

Hi everyone was hoping to get some help on identifying this green leafy algae that been driving me crazy. It grows in short tufts and has a curved leafy appearance with a lime green color. It attaches very firmly to the rocks and won’t fully come off even when scrubbed vigorously. If I try to...

I have this algae (or possibly something else) that’s on my rock and on corals. It doesn’t easily blow off and in fact is very difficult to remove. It’s likely not cyano as I just did a treatment with chemiclean and it didn’t help at all. Any ideas and how to rid my tank of it? Lowering...

Hi! First of all, I would like to thank you all for your help! Whenever I have a problem with my tank, you help me solve it ASAP! Now to the issue: In the past few days, I noticed that a white spot appeared on the top of my clownfish. I have no idea what this could be, so I want to hear your...

Trying to overcome my agae woes. All (98%) of my long hair algae is gone in the display tank, but now I have a stubborn Turf Algae growing. I saw videos of people suggesting spot treating each day where roots are more stubborn, but some threads on here seem to have me believe there is no such...

Good day everyone, I want to introduce to you all my Red Sea Max Nano G2 XL salt water tank. You may just simply look at it, follow with interest for updates, and please give me your honest opinions. My setup is only running a Red Sea NanoMat currently, and some Red Sea carbon just before the...

Nitrate is at 1.2 ppm Phosphate is at 0.06 ppm The corals have been growing like crazy lately, I did a 10 gallon water change Sunday Not sure if I should cut back on the skimmer for a week so the nutrients can rise back up. Any help is greatly appreciated, I went to California for 5 days and...

Hey guys any ideas if these blobs are feather dusters or something else? When I hit them with my scraper it appeared like it retracted. Almost looks like fuzzy jelly. Hard to describe but appear white/translucent. They reside on the live rock that is always shaded.

In the process of starting up a nano tank and I am ironing out my fish list. I would like an algae grazing fish, but because of the 25g nano I am limited to small fish. So do algae grazing blennies make a difference? Is there another fish for the job? I have also read that many blennies nip...

Specs are a 15g Nano reef waterbox filtration is a filter sock, and a protein skimmer that to be honest seems to work half the time. Automatic RODI water top off I don't have

Hey, this algae has coated my entire tank. I’ve a fake rock background on my tank which is also coated with it. I’ve no nitrate or nitrite or ammonia. I’ve changed my AI prime 26hd light to the “David saxby” schedule since, as It might be because I was running my lights too white? I’m wondering...

this is a blue glitter face Goni (aquacultured) that I received as a frag that was doing great until I accidentally clipped the very tip of a torch tentacle off with a tweezer - that tip proceeded to take off in the flow & landed directly on this at-the-time beautiful- blue glitter Goni. I acted...

Hi guys I'm having a problem with GHA and I'm trying to fix it with Flux Rx. I've dosed it Friday October 25, and I'm still not able to see any changes in the algae color or their root strength. Does anyone have any experience with this product and how it will work with GHA? On the back says...

Hello, I’ve finished setting up my sump for my 60 gallon breeder. I set this tank up a while ago using live ocean rock but I’m just now adding a sump and fish to it. The dimensions of the tank are 48.5" x 18.5"x 18". So far, I’ve only added a pair of clownfish and some soft coral and they’re...

Hello! I have this very interesting orange Algae (I think) growing around my rocks. Does anyone know what it is? Is it good? Bad? Should I be worried I recently had a drop on my salinity so maybe that is what caused it but don’t really know what it could be I have some imagines to help...

Back story. Ok so I have been reefing since 2016 and have had several tanks since then. I set up a folwer tank 155 with live rock from my lfs. I then set up another tank a reef tank 60 gallon using dry rock. No real issues so far. I then upgrade the fowler to the current 250 gallon and the reef...

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.
