green algae

My tank has been up for almost 2 months. Went through a very short diatom phase, i still get some on the glass. Now there is some greening happening but there’s no algae coming off it. What could this be? Disc Mag 1320-1350 Calcium 440 Alkalinity 9 SG 1.0255 Phosphates 0.02 Nitrates 10 Temp...

Hi. I have a Fluval Flex 123L which has been running for about 1 year now. I have always had a major green hair algae problem which I just put down to the fact the tank was new and going through the motions. I work offshore so I'm only able to do a water change once a month which is a 25%...

This is currently what my tank looks like Question 1) the brown algae -read a lot about it being good, but how much is to much? I also have green algae on my glass. Question 2) close up of rocks with micro bubbles - is this okay? Question 3) should I be running lights on a normal day/night...

Yes I know. GHA outbreak after the hurricane. Been battling it pretty well I think. Turned on whites to get better pics. it is a spongy red brown algae forming in balls before it spreads. It was only on the frag plugs of two Zoas, completely took them over. After a peroxide bath and a bit of...

This is my tank that I thought was doing pretty fine until a algae outbreak and I know it’s nitrates and phosphates, should I just let them stay and starve out their nutrients? I got 4 turbo snails and a emerald crab for a 20g. Also, how many corals is too many corals?

Having a nightmare with the algae on the back wall. The rocks are cured that way and I’m not particularly bothered about them (I read that they should turn darker and purple as coralline takes over) This algae is so hard to scrape away, I press as hard as possible with my scraper but it just...

I introduced three new sea urchins to my long island sound tank yesterday. Floated them as I thought was appropriate amount of time (about 4 hours) I also added a couple mummychugs and two green crabs. Upon returning to my tank this morning all three urchins are flipped on their "backs" with...

Before this one i had diatoms (they’re not 100% cleared out but are practically only on the glass, before they were everywhere) Now this green algae is everywhere and it’s quite ugly. My tank is about 4 months old.

Hi.. I have biocube 32 gallon tank for more thank 1 year. For last few days it started growing green hair like thing and it's growing fast all over my live rocks. Can I get rid of old rocks and add new live rocks with the fish still in the tank (clown & chromis) ? Please help.

Hello Everyone, can somebody please help me identify this algae. It’s really bushy and waves in the water flow. It’s growing on the back glass as well. Any idea if this is green hair or turf algae? What’s the difference? Any ideas to bring this under control? I added a Torchus snail and a...

Hi All, I am relatively new to Saltwater and would love some assistance with my current situation. I was a little excited with the cycle and did have lights on including white for some time ( I have learned since then). Can someone please assist in identifying the algae growth and let me know...

I should start by saying, I do not have all the answers, in fact, I hardly have any. After combing the forums daily for weeks, I realized that there are hundreds(thousands?) of threads concerning GHA. Unfortunately many of these threads have either gone unanswered, or the answers varied greatly...

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...

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...
