algae

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.

I've got some algae starting on a few rocks. I purchased Sea Lettuce macro algae 8 weeks ago from Algae Barn, so I'm wondering if that stuff has the ability to frag and grow elsewhere on its own readily, or if this newly emerged stuff is perhaps a green shade of Dictyota. Do I keep it in place...

Hi all, I have a 75 gal with sump. Lots of macro in sump and some in main display. Tank is 120 days old. Went through the high ammonia phase, went through the high nitrates phase, the Dino bloom, then into the bright green algae phase. I feel like I should start to see the bright green about to...

Hi. I’ve been dealing with this for a very long time now with diatoms growing on my sand and I’ve even reduced lighting a lot and they still keep coming. Now I just decided to ask if anyone knew what was growing on my rocks and how I can get rid of them and maybe grow some corraline algae. I’m...

On my zoanthid very frequently I’ve had these bubble things appearing on my zoanthids. I’m taking them out and popped them and put the Zoas back in the tank. All they do is pop up and I’m not entirely sure what all of this is. I also cannot get my zoanthids to grow anywhere on my rocks. I’ve had...

This started growing in my refugium and has started taking over the entire fuge. It puts down roots that are attaching to all of the live rock and bio balls. Can someone help identify? Is it a good algae or nuisance/threat? Thx!

We have chaeto back in stock until it runs out. $15 for a good baseball size ball plus $5 shipping. $20 shipped.

Having a nightmare with the algae on the back wall. The rocks are cured that way and I’m not particularly bothered about them (I read that they should turn darker and purple as coralline takes over) This algae is so hard to scrape away, I press as hard as possible with my scraper but it just...

Hi all, I have had this algae in my reef for a few months now. I believe it’s mostly turf algae though some appears to be stringy like hair algae. It’s very difficult to remove from the rocks like turf algae. I have been treating with microbacter clean daily for probably about 8 weeks now but...

hello, I ordered some algae and it will come in two days. I don't have a refugium, so I am wondering if I could grow algae in the sump without using the reservoir... I have a heater, lights, 2 return pumps, 1 skimmer and 1 reef mat in the sump

Hey all! Upon starting my Waterbox 20 journey into reefkeeping, I purchased these turbo snails at my LFS. They were coloured brown, and inexperience made me not question it. I didn't know about peroxiding snail shells, and added them. Turns out they were covered in lobophora algae. After...

Hi guys, I'm starting my first tank. I got my tank, dry rock, live rock, live sand, heater, power head, filter. And I was planning on getting a clown fish and adding API quick start to start my cycle. However I got busy and put it off for about 2 months, not really thinking that it would cause...
