Volcano. Many tks for the information. Yea I thought it was bubble algie too but seem to remember someone saying it wasn't, but very close. So far nothing in the main tank. Yea it grows like mad. And yea I have high nitrates. Can't seem to get a handle on reducing them. But my fuge is very dirty. Might have to attack that sometime. But I did notice that the growth rate of this stuff increased dramatically when I added the new growth light. Was kinda hoping that was the reason.

Anyone have any idea if I remove all this stuff, will it really negatively affect my water health, relatively speaking?

Is the turf algae you talk about, really short haired almost like a Brillo pad? I have that too in the main tank and harvest that into the fuge.

Again tks
