It's Turf Algae, and it will grow for a month or two, but should abate over time, once your tank matures

Keep it plucked and don't let it blow all over your tank
In the meantime ...
When I remove mine, I hold a cup of fresh water in one hand and pluck off the algae ( the whole growth ) with the other, dipping my fingers into the cup to rinse, and carry on with the next clump

It should eventually go away

Good to know. I'll start removing tomorrow during my water change. So far I only see one clump, but I imagine more are to come.

I think I will try a mesh bag filled with GFO. Obviously it won't be as effective as a reactor, however I'm guessing it's better than nothing. I don't have the heart to plumb in reactors, nor do I have the room.

Be prepared for some weeks or months of dealing with this algae, as with others

The key to our hobby is time ....

Go to either Google or Canreef and search SW algae ...

My turf algae started about 1 month ago, and it's still there, along with some other kinds, but, it's less than it was ...

The biggest thing for you to do right now, while your tank is maturing, is to not worry so much about what is happening, but to rather learn about what is happening and learn about what algae is OK and what is not

Read, read some more, and then read some more
There's lots of kinds of algae ... there's only a couple you have to worry about
Take a day or two and read about algae, then read about them again
You have to learn and learn and learn :razz:

Google search saltwater algae, reef algae
You'll find topics on these

Bryopsis algae
Caulerpa algae
Bubble algae

And many more

If you don't learn about what is going to grow in your tank, you are going to be back to asking again and again, when you should be ...
Knowing and learning and learning .... :smile:


The algaes that you and I are going through are normal, and there will be more

Learn about which ones are going to go away, and which ones you should remove ....

After your tank, and mine, starts to mature, there will be no more algae to fret over per se :smile:

Read lots and then you'll be happy with your tank :mrgreen:

Thanks for your responses. Greg - I'm prepared to battle!

I'm going through the same thing right now, except that my hair algea problem is of epic proportions compared to yours. I'm also using RO/DI water and have been running GFO in a reactor for the last week. I tested for phospates and the test came back as 0 as I expected because the algea is absorbing all the phospates

What seems to be working for me is the addition of 10 Turbo Snails and 30 hermit crabs. The snails are devouring it. Hopefully the GFO will help as well. Also I got some Cheato so hopefully that will help absorb some of the phosphates that the hair algea needs.

I suspect the root of my problem is my dry rock leeching Phosphate. I also did not acid bath my rock which I found out later maybe I should have done. I would suspect your rocks are leeching phospate as well. I think with time it will go away. So get some turbo snails and that should help. I also read that sea hares devour the stuff as well.

Good luck with your battle.

The only thing that really works on hair algae is a seahare.
Snails and crabs, even fish, won't even put a dent into a hair algae infestation, but a seahare just mows it down. Once the algae is gone though, you need to pass the seahare along to another reefer, as it needs a lot of algae to eat or it quickly dies.

It looks like bryopsis to me:

keep a close eye on it much harder to get rid of than hair algae as nothing eats it.

Have a look at the link subman posted
If your algae is feathery looking, then it's most likely bryopsis and you definitely want to remove it
If your's is soft and clumpy, it's turf
I have hermits that eat turf, but I'd need a huge army to keep it all down and I'm not interested in having that many :wink:

Hmmm hard to tell. I don't think it's bryosis but I really don't know. Thanks for the links and advice guys.

When you touch it, is it bristly, or soft ?
