Green Coralline Algae

[NeedBiggerTank]

I am curiuos as to why I've got so much green coralline algae growing on tank walls? There is pink too and one colony of purple - but mostly green. My live rock is covered predominantly in pink and purple coralline algae. So where is all this green coralline algea comming from? Is there any way to encourage more of the purple and pink to grow and less of the green?

Don't get me wrong, the green is OK - I just don't see it in other display tanks - just the pink and purple coralline. Makes me think maybe I'm doing something wrong!

BTW - I do use "Purple Up", in case that is a suggestion.

Green algae is usually not Coralline, easiest way to tell if it's Coralline or not is to use your finger to scratch it. If you can scratch it, it means it's not Coralline. Most likely it's just boring green algae...

The Coralline on the rock came with the rock, same as green algae. If you reduce the light, you will see green algae disappear, but not Coralline.

From Wiki:
Coralline algae are red algae in the Family Corallinaceae of the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white or gray-green.

Isn't the green type from deeper water? I too have the green coralline in my tank along with the pink, purple, red.
I like the green mixed with the others!

Doesn't how intense your lighting is, will dictate what color/type will take hold? On the other hand, IMHO, display tanks that have nothing but pink and purple coralline algae covering everything, to me looks "unnatural".

I wish I had more green coralline algae in my tank

Green Coraline is present along with the red....especially in new tanks, green generally comes first. Pelagic's scratch method is a good test. Water parameters should be checked, but what I find is when shifts like this start to happen, most people overlook how old their bulbs are. Bulb life is estimated only.....I replace mine between 6 months and 1 year. Sometimes a bulb will not last a year, and when your light output changes, shifta like this can happen.

As for using Purple Up...well, you would do better to use a real 2 part, such as BRS's 2 part. Purple up can end up throwing your tank off because you are not dosing in a method that lets you add only what you need.

IME, green is the first stage that later turns to pink/red/etc. It never has stayed green in my tanks.

This is definately coralline algae - it's the same texture and colonies are round. It's identical to the pink, just green.

I'll see if I can get a picture when my lights come on in a couple of hours.

+1 for Andy/Brandon. Green is mostly in newer setups and is replaced by Pink/purple within 6 months to a year. I rarely see it in mature tanks. I have seen pictures of it in other colors as well. Would be cool if you could keep other colors but the chemistry/conditions needed for our corals just does not support it.

The last L/R i bought from a vendor had plenty of Green,Yellow, White, Pink, Purple and Orange Coralline on it when it arrived. after a week it all turned white and never came back, Except for Pink, Purple and Red which i forgot to mention up top. The amount of light and nutrients needed are not the same in a closed system as the ocean and can not support these alga's long term in a closed system that i have ever seen. Though i don't think it's impossible to have different colors sprout up at times when conditions are right for it to grow, Most likely came in the tank on something and conditions were right for it to do well.

Heres a photo:

taken from behind the algae (so you're looking at the underneath side of the algae - the silly Copperband Butterfly just kept coming right up to the glass in front of the lense - so I could take the picture from the front!).

Very interesting

my green algae looks like that and even grows like that but its not hard like coraline,my urchine adores it though lol

I looked at my tank closely today, and found some green coraline, they are in a "not so bright" area. Is it the same for yours?
