coralline

Its neon green...

So this has been growing in my tank for about a month now, deep green patches, not really hairy or overly slimy, it grows only on the rocks, and it grows in expanding circles like green coralline algae does, except this is a much deeper green than coralline (I've had some of that as well), and...

So I bought this cured rock from a LFS for the 55 gallon that I am starting. I assumed that coralline algae comes in many different colors so I did not think anything of it. This one looks orange. I swear that in the past I have had something orange-ish like it in the past. I am just checking...

So I have a tank that's about 2 and I don't have any coralline algae, despite seeing good growth and healthy coral. At first I thought it was because I had a bunch of urchins but they were rehomed due to a lack of food and in the year they've been gone I still have none. I noticed patches that...

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'm thinking about sealing the top halves of all the dry rock by soaking them with liquid super glue. I got the idea from another discussion on here and confirming similar observed results with another reefer. In my 250 rebuild, the connections where I heavily glued together and are under high...

Is this dark purple stuff Cyano or Coralline? It’s not hairy and doesn’t come off when I scrape it with my finger nail. My tank is over 2 years old and this stuff doesn’t look like my lighter colored coralline. I’ve never dealt with Cyano so I’m kind of panicking. It’s on some of my live rocks...

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...

Does anyone know why my purple coralline is disappearing off my live rock? There are 2 with this problem. I do not have urchins or crabs and haven’t added anything new to the tank in weeks. The tank has been up for 10 months and the coralline has been growing nicely until now.

I am getting confused and concerned by how much calc and alk I am dosing since dumping 4 bottles of Coralline spores from Atlantic Reef Conservatory last month. Looking for some input and thoughts please. Here's the story. I started a new 400 gal tank on May 7th. Felt it was fairly well...

So my 90 gallon reef has been up and running for about two months now, and when it comes to cleaning algae off the glass I really just focus on the front and sides, without touching the back glass (mainly out of my own laziness of having to get back there with a scraper). At this point the back...

So I have the fever, The Coralline Fever. lol I have 3 saltwater tanks, two 75 gallons run by canister filters and a 125 gallon with 55 gallon sump/fuge, My 125 is almost 4 years old, both of my 75's are over a year old, and I have yet to get coralline to grow in any of them, and they have all...

Hi all! Tank is about 100 days old. Within the past couple days I’ve noticed these little dots on the back of my aquarium. There’s also a couple on the powerhead and a return nozzle. It doesn’t fluoresce but it’s a solid color and looks lightly pink. Can anyone help ID? Thanks!

I have regular purple coralline growing on my rocks. I also have this very light blue colored algea that looks similar and a hard green algea on some of my other rocks. Are these coralline? Also some white colored areas on my back wall. Is that the start of coralline?

Hey guys, I had this slimy red coralline pop up and growing. It seems to be competing with coral for . Checked all over and haven’t found too many things like it. Anyone have any experience with it? I was thinking about getting an urchin to try to knock it out. My nitrates are high and started...

Not sure if this is the right place for this question but my question is.........I have a bottle of coralline algae spores coming to seed my tank from "ADDICTIVE REEF KEEPING" online ....when i plan to seed my tank do i need to remove any of my carbon or should i turn my protein skimmer off for...

How to Grow Coralline Algae In Your Aquarium: The Simple Truth A guide to growing attractive red, purple, and pink algae in your aquarium

Hello, can someone post some pictures of what the beginning of coralline algae looks like?

This is the best picture I can get -- these are thin, brittle but hard shelves growing out primarily from this location. I have some LR near it that has some established blue coralline (can't get a good picture that isn't washed out from the whites). Please bear with my poor picture...

So I have had my 75g up and running for two months with dry rock and I'm curious about how someone would go about 'introducing' coralline algae into their tank. I've heard it can be introduced from shells of invertebrates but that seems inefficient. I know there are products that can "boost"...

I was looking into adding some additives to my tank to make coralline gore faster. I already have live rock, but I'm afraid the coralline is not doing well. I was looking into this products: Which one should I get? Thanks guys

Hi all I am a new beginner of saltwater tank. I am running my tank about 11 months. Few day back I have seen that some lime green color is spreading all over my rock. Is these green hair algae or something else. Please help to identify and how to control that. Some real picture are uploaded...

Hey guys, while I was doing a water change I noticed that there's some spots on my rock, not sure if it's the start of coralline algae(hoping it is). Can you guys confirm?Also unfortunately a menance of my tank has returned, it's the wavy algae and it is on just about everything almost...
