algae

I bought a sea sponge a few months ago. It was doing great for weeks, then fell over between some rocks for a few days. When I pulled it out of rocks, it has some white and brown goo on it. It looks like algae of some sort. I can see the orange flesh beneath, but the goo seems to be spreading. I...

Went away for a week and came home to this completely taking over my sump. Protein skimmer working very hard. Used up half my reef mat in 3 days. It feels very slimy and comes apart quite easily. The consistency almost feels like slime around a piece of string, but the second you touch it, it...

I just came back from a week long vacation and found this stuff has completely taken over my sump. Any idea what it is and how to get rid of it?

Hello! Rather new to the hobby here but my tank has been running for just over 6 months. I’ve had coral for almost 3 months. Went through a few different ugly stages already. I thought things were finally calming down where everything was clean again for almost a month and everyone has been...

So i have a 33 gallon long tank that is about 2.5 years old and I have never been able to defeat algae. The tank is overrun with bubble algae and GHA. I'm even dosing Vibrant (algaecide) but nothing seems to be working. Almost every week I have to clean pumps because they get clogged up with...

So I am starting up a new 22 gallon tank and planning on bringing my clowns and inverts over from my Fluval 13.5. Problem is the 13.5 has been showing signs of slight dinos from a rock that I had recently added to the tank after buying some anemones. I would love to move the anemones to the new...

The algae is green, i wonder if it's some caulerpa. I had some racemosa at the beginning but killed it (it bleached probably because of the lack of nutriments). Could you help me to identify this one?

Algae problem causes me to suffer after past 6 months and finally found out is my light is too long after chit chatting with in a fish shop. Anyway, recently the tank suddenly appeared many kinds of hitchhikers: a kind of algae,Vermetid Snail, one or two fireworms (At least looks like, it has...

I can't find any other algae that looks remotely similar. Has anyone ever seen algae like this? It grows in long vine like strands along the rock and has spread across all my rocks. Easy enough to remove with tweezers but can never remove all of it. Thanks.

@Randy Holmes-Farley Hello. I have a bryopsis and gha problem in my 150g dt and sump combined aquarium. I have tried manually scrubbing it off the aquascape however they keep coming back and now have taken over almost all the walls and rock. I have been reading. Lot about Fluconazole lately. I...

I started to notice some of this clear white stuff growing on my rocks can anyone tell me what it is?

Hi R2R Team, I've been battling a nuisance algae for a little bit now. I initially thought it was bryopsis but have tried fluconazole with no luck. I have tried manual removal which will remove the amount initially but always comes back. I have also implemented reduced feeding by reducing total...

Hi all! I seem to be having an issue with a nuisance algae. I would like to see if there is a "natural" solution to the problem before I try to attack it with chemicals. I have a starry blenny, a blue spot sea hare, and a smorgasbord of different snails, but none of them seem to touch the stuff...

Hi, I recently took over a tank with live rocks, and found out that there are serious algae problems with them. All rocks were kept in trash can with flow and heater. I was thinking of starting the cycling process with those established rock (there are some invertebrates and coral on them and...

Please Help me !! Sorry in advance if my english is not perfect I'm a french Canadian from Quebec. I really wish to solve my green hair algae problem because i just cant enjoy my tank as it is right now. every week im pulling out as much algae as i can with my 10 to 20 % water change but im not...

Hey folks, Need some input! Got some floating / suspended particles floating around the tank that just don't seem to get filtered out of my 75g saltwater tank - see attached pics. The particles don't look like food, but rather small bits of dead algae / dust (recently went on a big algae...

Hey guys, 6 week old tank and i noticed a stringy white thing that’s attached on my rock. Any ideas what it is and what’s causing it?

Good afternoon! I have a 6” magnificent Foxface that I ordered online that I’ve had for 2 weeks now. Still a little shy, but has been getting much more bold in the tank. The problem I’m having is with feeding it- the fish is only grazing in algae in the tank. I feed LRS reef frenzy and mysis...

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...

Hi all, I had a turf algae issue and used reef flux to kill it. I moved my chaeto to another tank during the treatment. It has some turf algae knotted into it. I do not want to add it back to the refugium with the turf algae in it in case that could add it back to the system. Is there a way to...

Hey guys, i’ve been getting this browny slimy coating over my glass but predominantly where my zoa is. I initially thought it was the zooxanthellae since it was sort of similar in colour, but now it’s in many more places. It comes right off when i clean the glass, but anyone have an idea to what...

Heyy guys, i need some help identifying what is on my sandbed. I have attached some picture od some sand grains under the digital microscope. Especially the red stuff if anyone knows please help id.

Hey guys! New to posting to the forum here, but this community has been an amazing resource for me on my saltwater journey the past year. Looking to see if y'all could help with my specific situation: I've had the pictured tank for about a year now, and over that last week and half I've seen...
