Too much coralline

[Softhammer]

Only one solution.A few Clams and several hundred Acro frags......

I got them, hundreds of them. They’ve done nothing as you can see.

My limpets love the coraline as well but mine seems to keep growing.

That's hilarious. And I thought my coraline growth was good. You sir are an expert coraline algae grower!

As others have posted, urchins will help - I have three and they are constantly chewing through it (and redistributing frags). Getting some acros and monties in there would help too. If you have a fuge, there's some types of macro algae that would help as well - for instance Halimeda species.

Oh believe me I’d love to get more frags of SPS. Problem is convincing the wife that lol. Little by little I’ll get more back in there. Even she says “your tank used to be much more colorful “.

Well dang, none of my rocks are fused together. Even though I have a low rockscape, think I still need to

Nah as long as the rocks are fairly stable. I have a blue tuxedo who can't move my rocks.

I pull the stuff off the side glass in sheets that you can grow frags on. I hate coralline with a passion. It will even grow over the inlets in my flow pumps and I have to dip them in acid every so often or else they will eventually grow shut.

Any Carribea Sea rock..Life Rock, Reel, does not matter, if it has that purple stuff it is the same; And if you dose your tank with minerals it will spread. This guy had the same issue, and turned beautiful tank, as yours was, into a purple home for Barney.

Are you saying the paint spreads to new rocks?

Some of that stuff is coated in purple epoxy.

That's not coraline algae...my guess is you have some of that purple real reef rock, which bleeds snd spreads on whatever it touches...your water is diluted with it now

Can you explain how you know this? This seems alarming if it is true.

My guess is that not much else is competing with the coralline for nutrients. Something is always going to grow...

I had coralline growing like crazy for a few months ....was adding more than 1 dkH/day alkalinity and it was mostly to feed the algae and not corals. At the time I had low NO3/PO4 and no other algae growing, did not need really clean the glass much except to scrape coralline. Now that I've got high NO3/PO4 and other types of algae blooming, the coralline has died back.

That's about it...Whatever that purple stuff is consuming the nutrients fast...off the subject a little, Green algae is not bad like some people think; it is actually the best phosphate controller and keeps the tank from having high nutrients, beacuase it is a nutrient magnet, but you need something to control it's growth to keep appearance up...Many who have algae bloom issue have the best defense, the algae itself...take some of the rock with plenty of algae out of the tank and place it in the refugium, if you don't have one create a temporary one with a rubber maid tube and couple of pumps...keep light on the tube 24-7 until the algae in the tank is under control.

Calcification slows down as building blocks go up... coralline grows the fastest with low N and P, but so do nearly all true corals.

 

[Whiskyclown]

LOL. Been doing reef tanks since 2005, this is definitely not cyano. Here’s a full white lights just now.

We'll send of that lol I need some on my tank

Lower calcium a litt and acquire a pincushion urchin ir two

That is not paint, the fish would die.

 

[AdamNC]

Just picked up a Red Tuxedo Urchin. We’ll see how things go.

 

[EmptyWallet]

show off, I'm jealous! Would take me 10 years to grow that much. I use red sea colors program, but not Coralline Gro - I thought that was just Alk in a bottle (and a few others already in the colors program) and a bit of a marketing scam, i'll have to do more homework if you think it works (too well in your case)...

 

[Admann]

Buy more frags to outcompete the coralline LOL

 

[garbled]

Just a note on urchins. I remember reading an article awhile back about how tuxedo urchins do eat coralline algae, however, the way they eat it was supposedly found to encourage it's growth even more... had something to do with scraping the rock clean. Can't recall details, was years ago. Just saying, maybe don't add 10...
