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...

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...

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...

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!
