coralline algae

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...

Hello, Im just seeing if someone would be willing to mail me a shell or something with coralline on it. I only have a 12g Nano, so I don't need much. I don't have any friends that are in the hobby and I find it hard to justify spending a lot in the retail sector for it. If so, please let me...

So I got a 25-gallon tank with a complete setup for freshwater fish, but I want to build a reef instead. I'm looking for the most affordable options for sumps, return pumps, power heads, and what all is absolutely essential to maintain a reef. I know that sumps aren't essential, but do I still...

Here to show off! Set up this 5 gallon AIO on Tuesday, the star of the show is meant to be the macroalgae, however, it is seemingly pretty sparse. Just wait for it to fill in! There's a lot of halimeda opuntia that I trimmed down to nubs before deciding to use the left rock in this tank, so I'll...

So I had a green hair algae outbreak, then an ammonia spike, I dosed kordon AmQuelPlus ammonia detoxifier, it kills ammonia nitrite and nitrate, and chlorine. Things started to bounce back. I lost 2 cyphastrea, and a birdsnest, during that ammonia spike, it went to 0.50ppm. my xenia has been...

My tank has been set up for a month and now these purple spots started appearing on the rocks. Can it be coralline?

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...

The tank is about 4-5 months old now and I can tell that the water parameters are becoming extremely stable with no fluctuations. I am starting to see purple/pink spots all over my rocks which I assume is coralline algae. The rocks are still super green and slimy though which I was told is...

What is the darker colored algae? It won’t blast off with a turkey baster and barely wants to come off with a blade. I know we have bits of coralline but we can’t figure out what the other stuff is. Any ideas?

I have had this frag for a couple months now and it has been a lesson for me in SPS corals alone. The issues I have currently overcome are high PO4, Alk stability and lack of flow for it. So now I have good polyp extension and the flesh is iridescent, making me think it is doing well. My...
