algae

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?

So I got a anemone that came with a rock it was attached on. The anemone moved from the rock and when I took at closer look at the rock it looks very strange. Is this some type of algae? It looks like it had tentacles growing from it and some other weird patterns. Please see pictures below and...

I fought the good fight with GHA and won. I also discovered I was bottomed out with Nitrate and Phosphate. I'm dosing Phosphate and Nitrate now so I can hold .05ppm Phosphate and 3ppm Nitrate. It was amazing to see my coral perk right up. Anyway that's another thread for another day. Now I have...

Hello to all and Happy Holidays! Currently having an issue with a clear film over most of the LR (can't tell if it's bacterial or an algae) and a small Cyano bloom. Tested water and got some conflicting results. What should I do? 11 month old 30 Gallon DT Drilled 10 Gallon Baffled Sump W/...

So I've been battling this battle for months now, I have had my tank for 7 months now, in the past I posted pictures of my tank and people told me that I had cyano. After a lights out phase and dosing peroxide, the cyano subsided, then came back. I tried mitigating but I just did manual removal...

Hello, I have been dealing with ulva in my DT for a couple of months now, and I cannot seem to get rid of it. I have a tang, snails, and emerald crabs. None of them seem to want to eat it. Does anyone have any other solutions?

been battle Dino’s on and off but this time these Dino’s will not go away. Decided to re identify but can’t really tell which one they are. Please help

Great condition with pump. Will post picks when I get home. Need quick black Friday money

Hey everyone I am relatively new to reef tanks and I have had this algae in my tank forever. I can’t find anything on it. It has a tank ish colour and it has a jello like consistency. I have no idea what it is or how to get rid of it but I would really appreciate it if someone could help me out.

Hi reefers, I have a preowned REEFER XL425, I started it from very beginning 2 months ago. A week ago it got through cycling so I bought a pair of Nemos, 5 mixed frags, 3 shrimps a 4 snails. Everyone look great. Except the fact, that the chemistry is weird and now the massive green outbreak...

Long story short, no clue what I was doing but amazed that I got some pics. Not sure the magnification is. It's kind of a reddish brown hair algae.
