green hair algae

Fast growing corals can save your tank....when I started reefing I read a lot of blog posts...and many warned of the dangers of green star polyps and pulsing xinia and the sort taking over your tank. I think this does a disservice to new reefers....here is why. Fast growing and easy to care for...

I have had my 25 gallon tank running for 11 months now. The rocks and back of the tank have a lot of green hair algae and I have been trying to get rid of it. I have kept feeding to once per day I have a protein skimmer. I have a variety of snails and a urchin which has helped a bit with also me...

Hello everyone, I have a 75 gallon tank that has been set up for three going on four months now and I am currently battling some pretty nasty green hair algae. I completely understand. There is the ugly stage however it seems like the ugly stage has not given up once on my tank I constantly...

I’m looking into doing a 3 day black out to try and help with hair algae. I have corals and 1 anemone in the tank. Does blackout mean all lights off for 3 days or just on a low setting?

I have a 125 reef tank with 35 gallon sump with an undulated moray, miniatus grouper, and picasso triggerfish. My cleanup crew consists of a handful of turbo snails (was around 20 now much less because of the triggerfish) and a horshoe crab and chocolate starfish. I have had much luck with many...

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...

In the past, I’ve typically kept my refugium livestock free, only having macro algae in it. Right now however, it’s being overrun with green hair algae. You can see I literally have GHA growing on my chaeto. I was thinking about placing a Pincushin Urchin in there to clean up some of that...

Hello Everyone, I had posted this issue in the algae forum but after some investigating and discovering new phone camera features... I am seeing an obscene amount of copepods everywhere... in water, on rock, glass, substrate. This seems alot more than normal. Since I have a Mandarin and am aware...

Hello folks there is some green stuff on my corals and my lice rock. Can you help me recognize this? And aslo does someone know if ot is harmful and how to remove it?

Hi all! I recently had a massive GHA or BHA? that I´m trying to control. But I noticed a neon algae between the Hair algae. I don´t believe its coraline since it seems hair-y like. Any ideas on what type of algae this could be?. My tank is a 15 gal running for 4 months now. Corals seem doing...

Hello, please excuse my English, it's not my native language. I'm seeking your help to obtain advice on improving my fight against derbesia, also known as GHA (Green Hair Algae) in English. Currently, my aquarium is equipped with a DSB (Deep Sand Bed) without a sump or skimmer, and I'm facing...

I tried manually picking off, buts it’s hard to get then used reef flux. But it didn’t work. Please help.

Hi All, Can anyone confirm if this is Green Hair that's starting to grow on some of the rock (the lighter rock was dry and has been curing in buckets with the live pre-tank). Tanks is around 6 weeks old and all levels are OK. I have some 5 turbo and 5 neccarious snails alongside a Foxface and...

I need to clean a rock out of water since it's full of GHA and I estimate it will take about 30 minutes to scrape it all off, spray H2O2, let it sit, then rinse with SW. I also have a mushroom on this rock but since it's on the lower part I can keep it submerged. Also, is spraying H2O2 really...

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...

I need some help from the vets around here. My 125 gallon has been up for 2 years come june. I've had GHA for going on probably 8 months. At first I tried additive solutions then realized those caused other problems just as annoying as GHA. For the past 4-5 months I've pretty much left it alone...

Hello everyone, I’ve been having issues with green hair algae in my system. I have a phosphate reactor and a skimmer in my sump that work fine but the green hair algae is taking over. I’ve removed it by hand several times and I’ve tried dosing it with algae remover but that doesn’t help...

So I've been in the hobby for 3 years, I have a 90 gallon mixed reef that has been very successful. I recently started up a 13.5 fluval evo nano, I used all established live rock from my 90 gallon system sump. The tank inhabits 2 clowns, an urchin and a narcissus snail, plus a few zoa frags...

I was curious what saltwater fish are most likely to eat GHA that can live in up to a 40 gallon tank. Already treating it manually and with Vibrant. Just wanted to see what fish will finish it off and keep it at bay Right now I have: 2 Clownfish Royal Gramma Baby Horseshoe Crab Valentini Puffer

I began my reef hobby nearly 6 months ago with a 13.5 Fluval EVO, and I've had great luck with it thus far (knocking on all the wood available). So far the only major problem I have encountered was a salinity spike that nearly killed my hammer (Beginner mistake- I relied on a cheap hydrometer)...

I have both GHA and Cyano at the same time how do I kill them both at once?

Can someone please help me identify this nuisance alage I am having for the last 2 months now. I have an established 5year old SPS dominant system. My Nitrate is between 0-5ppm and my PO4 is 0.04 checked with Hanna URL checker. All the inhabitants of the tank are doing good. VIDEO:

I had a velvet outbreak 8 weeks ago today that killed off all my fish unfortunately, I’ve been fallow since then but for some reason had a green hair algae outbreak as well as spikes in ammonia, my phosphates , alk, cal, nitrates, ph are all well within recommended ranges I’ve been able to take...

Hi, I'm battling green hair algae in my 14g tank. I started by getting phosphate levels under control and trying to maintaining levels of <0.1. Levels creep every few days, though. It's helping but not completely. According to my Red Sea test kit, the nitrates are undetectable, which seems...

Ahhh… So I assume you have GHA (green hair algae) and you have been scouring the internet for success stories and ways people have beaten it. I was in your place 8 months ago but most methods I tried ended up failing so I’ll share how I defeated it. So here’s the beginning… I purchased a frag of...
