I love that super clean rock look you only see in aquariums with cooked rock. My next tank switch I'm going to cook all my rock.

 Well that is my dilema, my main tank is spotless, however I only put 2 little pieces of the new rock in there. Both had zero algae on them, aside from a nice thick layer of coraline.
The stuff with very little hair and almost no bubble is all in my fuge where I want to promote algae growth. 
The only sucker with any red hair is all alone in my sump, in the dark 24/7.
