What is the green algea on my live rock

[jasonb87]

This green algea come up after putting on some T5's when my LEDs went out. I have new LEDs coming for put back on the tank. Was this due to the spectrum change with the T5? Start of coraline? How do I get rid of it if it's not good? It's just very unsightly.

It won't rub off and it doesn't look like hair algea yet

Jason I'm assuming your tank is fairly new and this rock that it is on was dry rock? This is completely normal for it to show up. You won't be able to scrub it off. It will go away in time brotha.

The tank is about 2 year

Old some some of the rock is new dry rock that I added. Will the green turn purple?

 

[jasonb87]

Can't figure out how to edit my post from tapatalk. Most of the rock has been in the tank the hole 2 years and some of the white pieces were added within the last 3 months when I changed some of the Aqua scape up

Ok that is why it's green cause it was added later. It will go away and coralline algae will cover the rock, it just will take some time. This was my tank a few years ago when I started with all dry rock.

Thanks for the info, the wife is yelling about it lol. Would purple up help any or just let time take its course?

 

[jasonb87]

Oh and I do dose cal and mag usually once a week as mine has been running pretty low

 

[FL_Reefer]

I would just let it take its course, you already have some growing in there.

 

[jasonb87]

OK will do thanks for the help

 

[FL_Reefer]

No prob

just a note, don't use purple up - it contains things that you don't need in your tank

Looks like green coraline algae to me.... Coraline comes in many colors, including green.

+1 this accurate. If it doesn't scrub easily it's coralline. Many different colors out there. I had green. Now most of it is purple

When I came back home from work this past weekend it was already darker than it is in that pic also seen some new purple spots. So it's just a waiting game now see to if it will all turn purple.

This is not coralline algae. It is a natural process new rock goes through. Coralline grows from the center out. As you can see from the pics, this is not the case. Yes it does come in many colors but this is not coralline. The rock will be covered with coralline in time if par. are kept good.
