algae

@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...

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...

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...

Pretty new tank, started to get a build up of detritus a few days ago and now there are small bubbles forming on the sand and the rock as well. Any ideas what this is and how to fight it before they blow up?

Hello fellow reefers, TWO QUESTIONS i. Anyone’s expert opinion on whether or not keeping a plant grow light in the same room as my aquarium is okay? ii. Also, could this artificial sun be the dominant factor in causing my excess algae growth? I have a quite young (6 weeks?) fluval evo 13.5...

Hey y’all so my tanks about 2 years old now I’ve been having phosphate issues which have caused major algae Dino cyano who knows what was at .92 phosphates now at .16 looks like it’s going away hopefully while i was fighting it I’ve been siphoning it off the sand bed and picked up too much...

So i’ve seen plenty of different methods to use H.P. to kill GHA The one that works best for me in to apply 1ml of 3% H.P. onto the GHA on my rocks (since they’re too big and have too many corals to just be taken out) My question is: can i use the one found at drugstores? Or do i have to go...

I've been having the Algae grow and i cannot identify it! I don't thing it's cyano because everything I read says it's green in freshwater aqariums but blue/red in saltwater aquariums. I dont know if I'm right or wrong but I recently changed from the red sea marine salt to the Coarl sea salt...
