Dry rock bubble algae.

[Doug]

Before I moved, I traded some of my older live rock for some dry eco rock or whatever its called. I have a small bit of bubble algae here and there. Its always been easy to clean off during water changes.

Now this new rock thats been in my tank for several months now, is just plastered in masses of small bubble algae. Never have I seen the likes of it. I just tooth brushed the heck out of it during a water change, {in a bucket} and flipped it over.

Really thinking of throwing it in the garbage as I dont see how its controllable. Anyone else have this problem with similar types of rock?
