hair algae

Hey need some help. I have a 15 gallon innovative marine tank filled with a few corals and bubble tips. Now my tank is also filled with hair algae I’ve been battle for awhile. Thursday I removed a good amount of hair algae basically half still got a lot to remove. I had to do a 4-5 gallon water...

Hi I was curious and wanted to know if anyone could help me out. Been dealing with this algae for a while now took a quick pic before work gonna test when I get home. But is this hair algae?

Hi all, Recently my small 6 gal cube is having a bit of a hair algae problem. Honestly I’m not super concerned, I remove most of it by hand and it’s not too bad, but i wonder: what inverts do you recommend that eat hair algae? I heard emerald crabs may do it. Also urchins, but I don’t have the...

Hello. My tank is about 8 months old 40 40-gallon all-in-one sponge in the filter chamber, skimmer in the next chamber, small refugeum in the next chamber then return 10 hours of light using a hydra 32 I've always had the algae issue this is not new, and not the worst it's been. I dose all for...

My first post on Reef2Reef. Excited to learn some stuff on here! I have a question about green hair algae. I started my Red Sea Nano XL (33 gal) about a month ago. I started it up with live rock and sand. Since starting it, I have added 2 clowns, 10 snails, 2 red legged hermits (that seem very...

Blade Hybrid Algae Reactor 16 • Purchased a turf scrubber to deal with a heavily polluted tank with nitrates of 55ppm and heavy hair algae. • Tank is 92g volume so I purchased the 16 version as headroom and the 10 inch might not benefit as well due to the tank being heavily stocked. Over the...

I'll preface this by apologizing for the long post, but I'm all out of ideas and my parameters don't tell the story happening in my tank right now, so a lengthy backstory is the only info I have. ICP results are below, but basicly corals started RTN/STN slowly wasting away along with red cyano...

Hello all! I’ve attached some pictures below of an algae issue in my 75 gallon 7 year old reef tank. This issue has happened ever since we got a new light- the blade coral grow. We had no algae before this light. The tank experienced a whole lot of coral growth with the new light followed by...

I haven't done an update on my 125 gallon tank in a long time, but now I need help for my tank. By accident I added tap water from my sink and as a result I have a massive outbreak of hair algae and cyanobacteria. I treated the tank before with chemi clean and not only did the cyanobacteria...

Hi all, I would like to get your advice about rebooting or not a tank. Mine is 50g that is 1.5 yr old. I started it with dead rock that I boosted with startup bacteria. It had a long nitrite cycle then was all fine. I used to have very tiny patches of dino/cyano/hair (not that expert to...

This has been taking over my tank. I siphon it out during water changes but it grows back quickly. Is this hair algae or bryopsis?

Strange question. I have a (small) hair algae problem in a pico tank. Some of the tufts reach about an inch long max, the rest is just a shallow fuzzy layer. Got a trochus snail to take care of the job, was told by several sources that they eat hair algae. Well, it definitely did. Maybe too...

Hey, I run my 60 gallon cube off an oase 350 canister filter. It works great, except for phosphates. Everything else is perfect (pH, Alk, Nitrate etc) but phosphates are through the roof, which is leading to a lot of hair algae. I’m currently awaiting a Venturi to arrive for my DIY HOB skimmer...

i’ve noticed this algae I believe starting to grow in a couple spots in my tank. Wondering what type of algae it is. Is it an issue or ok. Never see it before innky tank i did increase my light schedule recently.

For the last month or two I’ve been having a constant battle with brown hair algae. I’ve reduced feedings, kept lights on for only 4-5 hours, dosed my supplements only 2-3 times a week (before I did it once every day) and picked as much as I can every water change but still, it’ll pop up after...

At the beginning of this month I moved back to my parent’s house after a breakup. Before the move I had pretty much no algae in my tank but about a week afterwards I started getting brown hair algae all over my rocks and now it’s getting out of hand. Nitrates and phosphates are both at 0 and I...

not sure if this is a hair algae. It seems to have leaves rather than just hairy. Also the second one is clear and just floats and moves with the current so it’s definitely not an animal or critter. But what is it? Any ideas? Thank you!

Hello, everyone, I've been battling hair algae for a few months and am considering getting a sea hare to tackle the short-term problem. I have a Red Sea 350, and my sump is already quite full with a Reefmat, UV sterilizer, skimmer, and pump. I would like to set up a refugium with Chaeto, but I'm...

Tank parameters: 40gal Time frame of light: 8hrs; Considering a 1 day black out... Light setup is 3 blue bulbs and 1 white. Salinity: 35ppt Temp: 74F pH: 8-8.3 Alk: 9.6 Nitrate: 6 Phosphate: 0.2 (keeping low to combat the hair algae) Calcium: 420 Magnesium: 1300 Clean up crew is comprised of 10...

Hello reefing community, My parameters are: Nitrates 8.5 Phosphates .01/.02 Alk 8 Mg 1450 Calcium 440 I have some few hair algae. My corals look like if they are starving. My question is. Should i get my phosphates higher?

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?

Any advice as I feel like I’m fighting a loosing battle…. As you can see from the pictures I have a pretty bad GHA problem. It has been like this for a few months now (maybe longer) I’m picking out clumps weekly but it just keeps growing back, most of it is to small to grab with my fingers and...

I have a 13.5 fluvial tank that’s been running for 5 months-ish and I’ve always had hair algae issues with this tank. I keep the water a bit dirty on purpose since it’s my LPS and softies tank. What’s the best invertebrates or fish to get rid of the hair algae? I’ve tried getting rid of it by...

I've been struggling with dino an hair algae for about a year. Sometimes it looks like it's getting better then it just blows up. I've used both vibrant and dosing peroxide on my old 40 gallon... the problem I'm having is on my 150 gallon acrylic aquarium. Would peroxide be a good option? I've...

Hello, I have had this tank set up since October 2023 and it’s always been very “green”. Here are some pics of how it looked along the way; very nasty! As much as I tried to clean it the algae always grew back overnight! The hair algae on the top is getting shorter but there is now very short...
