algae

Looking for geo ar418. Will to trade or pay. I have a lot of equipment including other algae reactor and would consider trading a ar618 in like new condition. Thanks

Saw this spiky coralline algae on my frag, and it almost looks meaty. A bit clear and sticks out 2mm and 3-4mm on spikes. What is this? Should i remove it? I can get a beter photo later.

Hi everyone, I have like 3 emerald crabs, and I noticed only one of them have this like algae or hairy stuff growing on its back. Does anyone know what is that? should I be concerned? should I remove him? On that note, would they eat seaweed? i’m concerned that they don’t have enough food and...

Whatever it is, it loves blue light. Didn't see these at all for the first few months until I switched to more blue-intense LEDs, then a week later they showed up. Does not form mats. Sort of bunches together in small green lumpy masses. Apparently hates shade, does not touch any shaded...

Feel like this is cyano, but this is a well established tank and this stuff grows even in the heaviest flow areas. On everything... gravel, filter box/skimmer box, heater, and rocks. I'm considering adding a "Microbe-Lift Algaway 5.4 Algae Control Aquarium Algaecide" regiment, but I'm concerned...

I am having an algae bloom and need help getting rid of. I just added new ecotech lighting and that is when started. I cleaned the tank 2 days ago and already back. Is there a chemical I can add to get rid of.

I put in MAR 3181 into my 32 biocube today but the pump isn’t pumping any water. I’m thinking it might have to do with the tube itself possibly. Anyone else have this problem? I put in the back of the tank. I had a pump in the back there before and it worked fine. Anyone have any suggestions?

what kind of algae is this? i thought it was diatom because when i blow it off it turns to dust, but it’s started it look stringy recently

TLDR: Does bubble algae go away on its own over time? Since the beginning of my reef I was plagued with, in different stages, hydroid jellyfish, pineapple sponges, flatworms, and cyanobacteria. All of which managed to completely go away over time. Even the cyanobacteria completely disappeared...

Hey everyone, I had this algae grow in my tank initially thinking it was Bryopsis. However, I'm not sure anymore. When I first spotted it during my water changes, I just sucked it out of my tank. I decided to go all out with Reef Flux for more preventative measures. However, two weeks later...

Anyone ever dealt with curly algae before? I am battling some hair algae as well but this is different, grows primarily on rock and is thicker like a macroalgae. If you have dealt with this before would appreciate an ID and any tips on how you beat it. This is a 8 month old setup still going...

This is in a 20 gallon AIO with a protein skimmer, UV sterilizer (recently added) and some matrix carbon in the back. It seems to get less apparent at night which leads me to think it's Dinos, but the microscope couldn't magnify enough to get 100% verification. Yes my Nitrate and Phos need to...

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.
