That is the exact stuff that has given me a lot of problems. Good to know what it is. I haven't found anything that likes to eat it, and my tank is too small to support a tang.
I've had success by physically removing it as often as possible, and working hard on the standby methods of limiting algae control (RO
water, less feeding etc.)
I went to the drug store and bought myself a denture toothbrush. I've found it very effective at scrubbing this particular algae off the rocks. It tends to grow in places where there is a small accumulation of loose sand on the LR
. It won't grow well on clean live rock and it can't displace coraline. It just kills me to scrub my LR
, but I had no choice. The coraline actually seems to thrive on the scrubbing, but there are a lot of other creatures that can be deathly harmed by a scrub.
Also, if some of it happens to grow in a spot that isn't too concerning...let it be. That clump will take the nutrients that are available and limit growth in other areas. (kind of the idea of a fuge, without a fuge)
