Can you really keep Caulerpa in the main tank?
I have always kept Caulerpa in the Rose tank. It helps to keep the water clean and also adds natural color to the reef.
It has never gone asexual so I have had no problem with it.
But it will in my smaller tank where I raise a lot of it to sell.
So you must be prepared for it.
Signs to watch for when it goes Asexual is it will start to turn white on just a few fronds.
If you see that, the water will start to turn cloudy. You can not stop it by pulling the white
strand out of the tank, they rest of it will follow suit and go asexual also.
It does not do this often and I have not found out why it does this or what the conditions are in the tank when it does. As it does not do this in my tanks. But it did in the past when I had some in a tank.
So be aware that it can and if all goes at once, your tank will be white.
And you must pull it all and do a big water change. Also your skimmer will work overtime to help clean it out.
Some will come back if you leave root attached to the rock in the tank. But pull most of it out once it starts to show white on the fronds.
It does start to grow around the sides and up the front of the tank so it is pulled from the places that I don't want it. But I have never removed any of it from the back of the tank.
The Yellow Tang loves it and keeps it mowed to an even height along the back.
As you can see by the date in the picture below. I have been growing it in my main tanks
for many years with no problems, and still continue to.
Here are some new pictures of Feather Caulerpa that I now keep in my tank.
I have never known it to go asexual in the tanks so I keep it in all of them, not only for looks
but to help keep the water clear.
And I just love the looks of it.
