    How to Create Bright Pink Coraline!

    I do not believe this method is sustainable but I recently shifted the color of the coraline algae on one of my rockwork pieces from dark purple to bright pink. The first picture shows a closeup of the pink coraline. The second photo shows two pieces of rockwork, the left with the purple...

    Macro algea and coraline happiness- New light choice

    I have had this tank going in one way or another for over 10 years. Ups and downs , mistakes were made. It is a 30 gallon with 20 pounds maybe of live rock and some newish dry rock at the bottom. It has been in the New used tank for 5 months and coraline is growing well. I consider this the main...

    White spots on back of aquarium

    I thought it was coraline. The spots haven't grown or disappeared. Only more showed up. It's hard to get a better picture than this. They are literally like white peices of sand on the back of my tank. Thats it.

    King of the hill- Can nuisance algae be managed by increasing coraline algae load?

    I began my reef hobby nearly 6 months ago with a 13.5 Fluval EVO, and I've had great luck with it thus far (knocking on all the wood available). So far the only major problem I have encountered was a salinity spike that nearly killed my hammer (Beginner mistake- I relied on a cheap hydrometer)...

    Can anyone tell me what this is?

    Marco Rock In Tubs w Cor Alg Spores

    Hoping I can get some advice on my procedure here. Any help is appreciated! I'm 60% done with my build, so I'm preparing ahead of time for the tank and it's bio filtration. I got some Polypropylene Tubs and put my aquascaped marco rock inside. I know PP isn't quite as good as HDPE because...

    Will Microbacter clean kill my coraline algae in a bottle?

    I recently started my new reef tank, after seeding it I was planning on dosing Coraline algae in a bottle as well as microbacter clean. If I add them at the same time will they work in conjunction together?

    Is this coraline algae?

    So I have this all over my pumps, back glass and overflow also my return nozzles. I was wondering if it is nuisance algae or Coraline. I see purple, redish and pink coraline but never green. I blow it and it doesn't come off. I have to scrape it off if I want it off.

    What’s growing in my tank??

    Should I be concerned about this growth? Is there something I should introduce to curb the algae looking growth? I’m going to be implementing a refugium in the sump in a few weeks time

    How do you feel about Coralline algae in your tank?

    Its usually a decent sign of quality water conditions, but I’ve never been a big fan of the back wall covered in coralline. Looks a kind of dirty. But at this point I can’t really bring myself to take the time and scrape it off. Someone scrape this crap off the tank walls for me lol How do...

    Does Coraline Prefer Red Light?

    The coraline has finally started popping up in my tank! I’m excited, BUT, unfortunately, it only appears to be growing in my chaeto reactor :eek:. I used two bottles of bottled coraline about a month ago, I figured it was overkill but I wanted the purple and pink strains, and to speed up the...

    What eats coraline?

    My tank makes coraline algae like you wouldn’t believe, in 8 months all my live rock is covered with thick plated sections growing upward and splotches that are spreading over each other, the back glass and overflow are covered... and I’m having to scrape it off the front/sides every 3-4 days...

    How long does it take for coraline algae to grow

    Hello, I was wondering how long it takes for coraline algae to grow in a reef tank? Does it have to be introduced to the reef tank some how or does it just start growing? Some information on it is what I am looking for, and maybe some pictures of reef tanks that have it.
