green algae

So, I have had this 13.5-gallon saltwater tank kit for a few months now and its never stops having loads of algae in it. I do water changes every week from the water from my local Petco, but I also have my own ROM but it's too cold to use it since I connect it to my hose into my basement. I just...

Hi there, i hope you al doing ok. This green and red stuff has grown inside back muy tank, is it a bacteria or is normal or what. Im a begginer. And after all my fish died from brooklynella, some of you told me to leave the tank with no fish for about 2 months and that's what I'm doing. Also...

I've had this algae few months back (did some googling but came up with no conclusion). Did fluconazole treatment for 3 weeks and they're gone. But in past week or so these things started to appear on some parts of rock. I don't wanna do another fluconazole if there's a more natural way. Would...

Hello, I am currently battling prorocentrum dinos and am making solid progress. I have a forest of GHA now, but it is now becoming problematic. It is housing stray dinos in it, while also suffocating my Xenia. Even though it is a competitor for the dinos, it is also a major nuisance. I want to...

Hello guys, I’m need some help to ID this Algea bloom in my tank. I had a lot of hair algea in my tank, so I did a fluconazole treatment, and it worked really well. Then I did a large water change, and after that I got this green algea all over the sand. I know my nitrates might be high, but...

Hey another question, definitely have an emergency on my hands and need to know what to do ASAP. As much input as I can get would be appreciated. I have a 29 gallon tank about 3 months old housing two ocellaris clowns and a bunch of mushroom corals. 3 days ago we added some new tank mates 4...

Hello just messaging from the Arizona area, looking for some input. I’m fairly new to the world of saltwater aquarium care and could really use some advise. We have a 29 gallon tank about 3 months old housing two ocellaris clowns and a beautiful bunch of mushroom corals who have been doing...

Been dealing with this algae for a little bit now and it's just getting out of hand. Starting to grow on coral skeletons even with scrubbing and removing it regularly. Can someone tell me what this is? Having a hard time 100% IDing it. It is some sort of green sheet algae that grows in layers...

I’ve been battling GHA for a few months now and It’s upsetting because I got it on a frag plug from my LFS. It has only spread a little bit and it pulls off easily so my nitrates are >5ppm and phosphate is around >0.15. I have tried flipping rocks upside down to cover the GHA, manual removal...

Can someone tell me what algae I have on my rocks and is it good or bad. Also what the white marks are on rocks and snails shell, aswell as the purple tip on snails shell. Any advice will be appreciated

I have been extremely patient going through my cycle and it’s been quite fun but I’m tired of it! Does anyone know when the different types of algae will start to disappear? my tank is 6-8 months old and my nitrate is sub 5 ppm. Also, how can I control green hair? it’s getting bad..

I've had my tank running for a few months now. I cycled the tank with microbacters cycling kit, the cycle went great and was done within a couple of weeks. This sort of dust algae appeared about two weeks ago and then some GHA. I added 3 emerald crabs to keep up with the hair algae but now the...

Starting to get a little out break so I thought I figure out how everyone else deals with this.

Hi guys Got some algae issues. But before I go ahead and do something about it I wanted to ask your help to identify the algae, so I am 100% sure. I think it’s green and red Cyano bacteria. But will be great if you can please help. Tank is about 3 months old. Cheers, Shiv

Hi everyone, have some green algae that has been growing in my tank. Im not sure what kind it is. I don't think it is green hair alga because it doesn't look thin enough. Can someone help me ID and potentially shed some light how to regulate or manage these? THANK YOU!

I have a hard green algae growing on my tank. I have been having to use a razor to get it off of my glass as the magnetic scrubber i normally go over the glass with can’t remove it. Any ideas as to what sort of algae this could be, it is a brightish green, not like coraline Thanks

Went to bed last night and all was good with our tank. Woke up and now we had a bloom of green algae. What would cause something like this and what can be done to remedy it? We have a Red Sea light set to run at 70% White and 70% Blue for 8 hours, moon for 4 hours at 15-10%. We went off what...

Hello all! First time salt/reef tank keeper- I have a 20G Nuvo that has been cycled for about two months now (up for a little over 3 months in total), started with live sand and dry reefsaver rock. I do a 5gal water change every week (with RODI, 0.00 TDS), and also vacuum the sand bed while...

Hi all new to the forums. I've searched a bit, but have not found quite what I was looking for. Or if I have it's been worse then the stage I'm at. But as my title states, I have a BioCube 32 that's been up for just about 3 months. It's been a month since diatoms have disappeared and all seemed...

What is the actual cause of green hair algae? I have read so many differing opinions on this. Maybe its all of the below: 1) high nitrates 2) high phosophates 3) Out of balance nitrates and phosophates (redfield ratio) 4) high silicates 5) Not enough CUC 6) Too much light 7) All of above 8)...

Hi everyone, hope everyone is doing well! I’m battling a green hair algae outbreak, I didn’t always have green hair algae but since I introduced my goby into the tank, it seems my algae has skyrocketed. Does anyone know if the unsifted sand being sifted for the first time since I set my tank up...

Just discovered my Valentini Puffer going to town on a patch of gha on my live rock. I’m wondering do puffers usually go for that,? Maybe some copepods in there, hmmm
