coralline algae

These little white coils are growing all over my base rocks and my back glass, any idea what they are? I’ve tried picking them off but they won’t budge.

Hello, I have had my tank up for 8 months now and I have what I believe is coralline algae growing. I just need some help identifying because it’s not bright pink. It starts off green then transitions to this grey on the glass. The stuff on the rock is bright pink so I am pretty sure that is...

Hey all! I have a 10+ year old 24 gallon tank at home that is self-sustaining, but has tons of Coralline algae in it. I know some people like it, but I don’t. Can anyone give any tips on what clean up crew to add to attack this? I was thinking a zebra urchin and some trochus snails.

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...

Taking down my tank and selling all livestock before I sell the tank/equipment. Rock has been in the tank for approximately 6 years. Lots of purple coralline algae on the rocks. Also included are all of my coral. Tons of mushrooms (3 different types/colors), a leather coral, a large...

I got this frogspawn from the lfs on Thursday. It looks the same way in my tank that it did in the shop. When the lights went out and the polyps retracted, I noticed some coralline algae on the stalk and I’m a bit concerned. It seems really healthy but I’ve read that coralline only grows on dead...

Hi all, I recently have been trying to figure out a way to use an ultrasonic transducer to clean off year old coralline algae that is incredibly strong. Normal plastic scrapers don’t do the job and metal ones will cause scratches. Attached is a video of a test I did using a handheld dental...

Does this look like the beginning of coralline where it’s green and turns pink later?

I’m looking to buy some snails, the seller has these listed but I’m trying to figure out if this is a thin branching coralline or vermetid snails covered in coralline.

I recently cycled my 45 gallon all in one tank and added my first inhabitants: a pair of clownfish and a Mexican turbo snail. The Mexican turbo snail has some coralline algae growing on its shell and I was hoping to use it to seed the tank rock, consisting of Caribe Sea live sand and BRS Marco...

Hey all. I came across some bottles of CoralUp/PurpleUp from Carib Sea of unknown age. Since this a mineral supplement and contains no living organisms (or it shouldn't) I figure as long as I give it a real good mixing to get everything homogeneous I should be fine to use it. I've got a 4 year...

Hello, I’ve recently run into an issue in which my coralline algae is bleaching and I’m hoping to better understand why it may be happening. I’ve recently upgraded my lighting to an aquatop marine (days ago) from the “freshwater” aquatop light I had for a few months. I know I’m not having an...

I was given coralline algae from my LFS. But there seems to be hitchhikers. I’m thinking it’s a chiton. But not sure what else could be on it thoughts? Thank you

Hey guys, I’ve got coralline algae crusting all my lps. And basically has been choking them out. Is this a thing or could it be just a coincidence that they die after the coralline encrusted them? Any thoughts or advice would be swell.

So my tank is 2 years old now and there is no coralline algae well the was at one point but then I accidentally killed it with Vibrant I really have not seen any since how can I get it to grow faster and will I have to introduce it again?

So at first I thought this stuff was green coralline algae but the more I looked into it I realized it’s probably not. Can anyone specify what exactly is this green stuff on my rocks?

Hi everyone, My tank is 2months old, does the "purple" speck stuff on my rocks look like Coralline Algea? I run my lights for 8hrs per day. The first to arrive was the bright green algea, its not slimy or brown so I don't know if i'm in the "ugly" phase or not. I've had crabs and snails in...

I started my tank out on November 4th with dry rock. On November 13th I added a bottle of purple helix and a bottle of pink fusion from ARC Reef. My tank cycle was still underway and didn't complete until around the 19th of November. Today, December 10th there are small pink and purple spots...

Up until a little over a year ago, I always assumed all the hard, red encrusting algae we find in our marine tanks was just another variant of Coralline algae. Boy was I wrong! I eventually came across this site which made me realize that this "red Coralline" might actually be of the genus...

Hi everyone, I have a 72 gallon bowfront tank and I've noticed small patches of coralline algae starting to grow on the glass. What's the best method to scrape it off, without scratching up the glass? I'm most concerned about scratching the curved front panel. I've seen a few different...

Hello fellow saltines, My tank is going on about 3 months old and now I have what appears to be something red on the sand, glass and is starting on my rock (note: the rock is the CaribSea LifeRock, the purple colored type). I have just this single rock, live sand, a hi Fin goby and a pistol...

Hey everyone, I have coralline algae growing on my front glass. I know that’s a good thing because my tank is mature and healthy but it’s also annoying because it’s so difficult to remove. My question is what would be the most effective way of removing it without an expensive blade or scraper...

Hi everybody, I am into my second year of reefing and have still no coralline growth. Here my story: I started out with a 4 gallon pico (dry rock and life sand) cube which I cycled and that was the only time I had 2 or 3 purple spots show up on the rocks then I had a diatom bloom. The purple...

I have had my tank going on 4 years. I almost crashed it a couple months back but brought it back from the dead. This week I accidentally dosed too much NoPoX and yesterday discovered all except one of my clowns died. I killed my green clown goby, platinum clown, hawk fish, and six line wrasse...
