The green you are seeing is Green Hair Algae, a Lawn Mower Blenny and some hermits should take care of it, just be prepared to take the Blenny back, the starve rather quickly as soon as they run out of algae.
I have a outburst of the hairy algae all over LR. was wondering if I can take out live rock and clean them up? instead of depending on a clean up crew... I read in a book to remove live rock for annual cleaning. is this done because it has been 1 year how is that for timing.
I think the algae is from calcium additves.
Sorry it was about removing gravel, notLR and rinsing it and returning to the tank, after a year.
