algae

Does anyone know what this is, I can’t find anything like it online.

Hey guys, Is anybody using raw spirulina powder to feed your copepods (or other types of zooplankton), corals or other creatures like fish? I use an addition of spirulina in fish food and I would like to use it more, as it's healthy and cheap, but I wonder how successful would I be with a...

So ive noticed this algae popping up in my tank over the past few weeks. It is on the sandbed and rocks and I have looked it up and have not been able to identify it. It is almost fuzzy little balls that coat the surface of my sand and rocks. It definitely doesn’t appear to be one of the...

Hi I have a new in box Skimz Algae reactor that won’t fit under my tank in my sump….so selling it 200.00 or best offer shipping available.

Hey guys! Well my 310gal has been up and running now since the Saturday of Labor Day weekend. I’ve had lights on it now for a couple of weeks. Just put my permanent light setup(coral cares) on it last weekend and have them on a 10 hour light schedule at only 20% intensity right now. I used...

What’s up guys here is some pictures of my 2 new hermit crabs I added today. Looks like they are loving it. I bought some algae pellets for them to eat since I don’t have algae growing right now. Let me know what you all think!!

Macro Algae Owners!!! I’ve recently switched over into the macro world and notice my red macro starting to gray out or become white. Dying or detritus build up? Are these signs that it is dying? I believe my tank has more than enough nutrients but I could be mistaken. Maybe it’s flow because...

This stuff showed up almost instantly, 7 week old tank and last few days I've been adding PurpleUp to help the corraline grow. I cant get a good pic but its a layer ontop of my rock and its VERY WHITE. I read it may be bleaching but this is new growth. I have very little flow in the areas...

The other day i noticed these tiny green/brown strands of what i assume to be algae on the glass of my new tank under only the lit up side (one side does not have a light over it yet). The tank has been running for almost exactly one month in total and only 6 days with a light on one side...

I'm wondering of anyone has any tips on removing hair algae from a goni frag. The algae is growing in between some polyps not on the plug. It's an amazeballs goni so I really want to clear this up without risking the coral. Thanks

I noticed two of the frags I added to my tank about a month ago are growing bubble algae. What's the best solution here? Should I take the frags out, remove all algae, and rinse off with tank water? Does that risk spores? Or could I cover it with some super glue and hope that stops things? Or...

I have a ice cap medium algae scrubber only about 7 months old, I bought from brs. Asking $225. Shipping from Atlanta

I believe it is hair Algae on the rock but it’s not green more like white. And if so should I leave it in the tank because it’s beneficial? or remove it completely. I attached a video

BLEMS - Phycology Nightlight - My original design! - $75 shipped This is a simple design, but it's taken me a while to get everything resolved. The Phycology Nightlight is essentially a miniature wall-mount aquarium equipped with a mini LED lamp to grow a live phytoplankton culture while...

Got this acan off the World Wide Corals Sale a couple weeks ago and something has just started to grow on it. No idea what this is can’t find anything on the internet. Video and photo attached.

Hey everyone, I have been battling prorocentrum dinos for 1.5 years at this point. It likely started due to phosphate bottoming out as well as me using tap water. I am a student so I'm a little tight in the financial department so it took a while to get an RODI. My params: Alk 8.6, pH. 7.9, Calc...

Hi Reefers I am looking for a definite answer on what kind of algae I am dealing with here on attached photos (Q: Is it green cyano?). It started appearing about a week ago; slightly more every day. If anyone have any suggestions on how to battle this, i'd be all ears. The tank is 5 months...

Hey all, I Purchased an Acan frag and put it in my tank yesterday. Last night it had a ring of color on the sand under it and then woke up to what looked like hair algae growing from the sand bed around it. Is this common of an Acan or did it being in some algae with it? Any help would be...

Been dealing with this nuisance for a month now. Turbos don’t seem to live long enough to keep it under control. I’ve been doing manual removals but it just keeps growing and growing. Any insights would be appreciated.

My tank (32.5gal) has been running around 4-5 weeks now, and is starting to come alive. I'm trying to identify the algae I've got going on in there right now. I know I have some diatoms (on the sand, some on the rocks too), but I've also got some pink and green algae coating the rocks and I...

Over the last few weeks, I have seen a new algae outbreak and I’ve been unable to properly ID it. It seems to be encrusting and does not come off with a tooth brush. My CuC doesn’t eat it. My LFS suggested a pinchushion urchin, but I’m wondering if there’s an alternative. I don’t want the...

My first take is literally just algae, taking over the tissue. It’s still spreading like wildfire so not so much concerned just curious for knowledge.

Hi, recently I noticed some black stuff started growing on my rock. The thanks is around 6 months old. Should I worry? It’s pretty hard to the touch but feels more “slippery” than coralline.
