algae

hey guys, recently i've gotten into salt water aquariums and currently have a 13 gallon AIO tank hosting mushroom corals, a damsel fish, and a few crabs aswell as my macro algae. everything used to look so good but after a while the flame macro started to go opake as well as growing some sort of...

Hello, I have had this tank set up since October 2023 and it’s always been very “green”. Here are some pics of how it looked along the way; very nasty! As much as I tried to clean it the algae always grew back overnight! The hair algae on the top is getting shorter but there is now very short...

I am dealing with something in my tank that I can’t identify. It looks similar to GHA but is white. It flows similar to GHA & comes off objects easily with a toothbrush. It is invading my tank and is killing my corals. It appears to creep up the base of the skeleton and maybe suffocate the polyp...

Hello everyone, In the last month, this algae (video attached) has been appearing in my aquarium, and I can't seem to eliminate it. I would like to know what type of algae it is and how to get rid of it. Things I have done in chronological order: - Tested my phosphate and nitrate levels to...

Hey all, I have a hammer that’s not opening, and it has a dark, jagged, stuff, and crusted on its stem. I’ve read threads about algae, but I assume the algae would be soft, but maybe not. I’m pretty new at this. This stuff is hard like tree bark. I have another hammer in the tank that’s...

Coralline algae. It’s growing really fast and taking over. Does anyone know how to treat it? Thanks

I’m gonna have the vinegar take a seat on the bench for a bit.. Iv been going straight to this for years to clean my stuff… soak 12-24 hours. But every single time I’m disappointed in the vinegars performance. Still end up scrubbing like crazy and to be honest a lot times after 12-24 hours, I...

I’m thinking this is just green hair algae and some diatoms, but just figured I’d check with some people who are more experienced. I also have hydroids which appeared two days ago. Any concern with them? I was told they would go away on their own?

I recently bought two trochus snails two days ago, while the other one is doing fine this other one keeps falling on his back, since Saturday I have righted him 15+ times, he can't seem to right himself. I put him on the rocks and he falls off, I put him on the sand bed and I come back and he is...

I have some hair algae going a bit crazy, siphoning during a water change helps but it’s not helping enough. I would like to get a fish or two to help reduce the algae build up and work well with my plans. I have a 41g cube tank with a few corals and more arriving this week. I have cleaner...

I recently started my first reef tank. We went with a 75 gallon tank and went with the Fluval Fx6 canister filter. We currently have 7 clownfish and about 30 pounds of live rock, as well as 70 pounds of sand. I am completely new to the reef world and am starting from the advice of my local fish...

Can someone tell me what is growing in my Sump tank? This is the largest growth but there are other spots. Should I remove it?

I’m at the 8 month mark, I’ve had dinos and cyano and finally am moving on to the next stage, or so I think. I’m getting this algae and I am torn as to if it is either turf or GHA. My algae CUC died off during my dino outbreak and before buying them again I want to make sure they’d be sustained...

Hi folks, Trying to figure out my next course of action. The past 1-2 weeks I've started to see a rapid growth of what appears to be Cyno and a certain type of algae which I'm unable to confirm exactly what kind, still new to all this. I'm currently doing a 72 blackout to see if that helps...

I have been battling with this algae im not sure if its dinos or cyano or what but i have been doing weekly water changes but it just doesn’t seem to go away does anyone have any suggestions on what I could try? Even just identifying what it is so i can at least get an idea on what im dealing with

I had a lot of hair algae at one time. I accidentally cleaned too much rock with peroxide and knocked off the biology. Dino's came out, did 3 blkouts over the fall. Eventually the stones became heavily overgrown with fluffy unknown shrubs over time as I started to regain the previous light...

Tank is about a week old. Used bacteria live sea water, and a buddy with a 300 gal gave me live rock that’s been in his sump for 8 years filled with copapods. Seeing this algae that almost looks like burnt rock. Is this normal?

So this has been growing in my tank for about a month now, deep green patches, not really hairy or overly slimy, it grows only on the rocks, and it grows in expanding circles like green coralline algae does, except this is a much deeper green than coralline (I've had some of that as well), and...

What type of algae is this? I need to fix it.

I had a brown/green algae problem a while back that was completely eradicated but now it’s coming back looking different - it has bubbles. I did increase light in the tank to help my corals regrow after the past algae bloom, since i dimmed the light for a few weeks to control the algae. My...

Day 18 (and Day 5 of AI Grow Blades). What's this green stuff? Diatoms or else? Current inhabitants: 1 Sapphire Damsel and 1 Coral Beauty Angelfish — both from Biota. Very peraceful, don't interact with each other at all. I also purchased 2 Fancy Peppermint shrimps from Biota but I am not able...

For the past few weeks I’ve noticed these weird little green algae bowls growing on my rockwork… not sure if these are micro or macro so I apologize if I’m in the wrong spot. I can’t find anything resembling this anywhere but it’s hard to search when you don’t know what you are searching for…...

Hey everyone, I've finally decided to get started again after a year of not touching my tank and could use some advice. Around last Thanksgiving while at a tech conference in Vegas, there was a power outage, and my apex for whatever reason didn't kick back on after power returned. I came home...

Hello! I recently have noticed my sandbed getting dirtier than normal. I will do my daily maintenance of stirring the sandbed but notice it will return in less than an hour. It also seems to almost fully disappear when the lights are off and return when the lights come back on. I read I could...

Hi, does anyone know what this is growing in my tank and how I can get rid of it?
