I've had significant hair algae issues every time I've used dry rock, but not bubble algae issues. I did introduce bubble algae to my system on a frag, so we'll see what it does.
I've decided that dry rock needs to be cooked. I know we're told that it doesn't, but I no longer believe that. I'm convinced that it leeches phosphates. I've just ordered 25 more pounds, so we'll see if cooking it changes anything.
