algae

Greetings! I’m generally just a lurker, and I don’t usually post. But I’ve run into an issue that I’m not sure how to handle, and I wanted to see if the crowd here might have some good ideas. Background I have a 75 gal reef tank (probably around 80 gallons total volume). The tank has been...

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...

Hi all, I was wondering if people could help identifying the below algae. It is a rusty brown colour,… My war parameters are all normal and everything is doing well but this algae has started to appear on my sand bed and it contains air bubbles.

Hello all, have been battling this strain of what i assume to be bryopsis and bubble algae which is starting to come around for me. Just wanted to see if anyone can id this algae for me as bryopsis, dinos, etc. Tank is 1.5 years old, fluval canister(drilled tank is in the works as we speak)...

Noticed this on one of my rocks amongst some GHA, floats like some kind of balloon stuck to the rock. Does anyone know what it is?

So a little background the tank is about half a year old now. I have higher than desirable nutrients Nitrate is at 19.5 and phosphate is at .07-.17 (Hanna issues) I have a refugium going below the tank in my sump i do weekly water changes of about 35 gallons. (the tank is a 90-gallon display and...

Can anyone help identify what is taking over my tank? I don’t have access to a microscope to check it accurately. Parameters: Salinity 1.026 Temp 78f Po4 0 (Hanna ulr) No3 0.25ppm (red sea pro) Alk 8.7 Cal 440 Mag 1340 I cannot get detectable nutrients (apart from some nitrates when I feed...

Not sure if this is a good place to post this(sorry if it should have been somewhere else) I’ve been slacking the last few weeks on cleaning the glass on my son’s tank. Now the magnet by itself isn’t cutting it. Would the scraper attachment help? I’ve never used a scraper before. Look at the...

Hello Reefing Community Im looking for knowledge or some one who can help. I tought my tank was doing great, i tought my tank was full of coraline algae. A wired looking coraline algae. it looks a bit more red or violet. it has a different kind of texture, almost as a sponge but a bit...

I have been looking a macro algae and I heard about the macro lady and was wondering how good is the algae they have?

I woke up overnight and all of this algae appeared out of nowhere it seems, what inverts will take care of this. I am considering hermit crabs.

Nitrate 6ppm Phos 0ppm What should I do?

I have this slime on my sand bed and on some of my rock. The slime sticks to the rock and sticks pieces of sand to it. I can’t suck it out with a siphon the sand that sticks to it weighs it down. I have to manual remove the slime and the sand that is attacked to it as well.

Hello everyone, I am just looking for some recommendations. I am currently building a 75 gallon tank and over the course of the last 2 to 3 weeks have been buying live rock for it. I started off with around 10 pounds in a tote with a powerhead and heater The next week I got another 15 pounds...

Has anyone seen spots like this on epoxy before? Not sure if it's algae, a pest, some sort of process with the epoxy, or if the crab or snails have been picking at it? The tank has been up and running since the beginning of January. I added the epoxy about 2 weeks ago right before I added a...

hey guys, recently i've gotten into salt water aquariums and currently have a 13 gallon AIO tank hosting mushroom corals, a damsel fish, and a few crabs aswell as my macro algae. everything used to look so good but after a while the flame macro started to go opake as well as growing some sort of...

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...

I am dealing with something in my tank that I can’t identify. It looks similar to GHA but is white. It flows similar to GHA & comes off objects easily with a toothbrush. It is invading my tank and is killing my corals. It appears to creep up the base of the skeleton and maybe suffocate the polyp...

Hello everyone, In the last month, this algae (video attached) has been appearing in my aquarium, and I can't seem to eliminate it. I would like to know what type of algae it is and how to get rid of it. Things I have done in chronological order: - Tested my phosphate and nitrate levels to...

Hey all, I have a hammer that’s not opening, and it has a dark, jagged, stuff, and crusted on its stem. I’ve read threads about algae, but I assume the algae would be soft, but maybe not. I’m pretty new at this. This stuff is hard like tree bark. I have another hammer in the tank that’s...

Coralline algae. It’s growing really fast and taking over. Does anyone know how to treat it? Thanks

I’m gonna have the vinegar take a seat on the bench for a bit.. Iv been going straight to this for years to clean my stuff… soak 12-24 hours. But every single time I’m disappointed in the vinegars performance. Still end up scrubbing like crazy and to be honest a lot times after 12-24 hours, I...

I’m thinking this is just green hair algae and some diatoms, but just figured I’d check with some people who are more experienced. I also have hydroids which appeared two days ago. Any concern with them? I was told they would go away on their own?

I recently bought two trochus snails two days ago, while the other one is doing fine this other one keeps falling on his back, since Saturday I have righted him 15+ times, he can't seem to right himself. I put him on the rocks and he falls off, I put him on the sand bed and I come back and he is...

I have some hair algae going a bit crazy, siphoning during a water change helps but it’s not helping enough. I would like to get a fish or two to help reduce the algae build up and work well with my plans. I have a 41g cube tank with a few corals and more arriving this week. I have cleaner...
