hey guys i have a 8 week old tank and i have a problem with green hair algae on my rocks. I have heard that this is common in the early stages and that it will go away in a few weeks? Is this true or should i move in the direction of manually removing most of it by scrubbing the rocks?
Here is a pic

You could add some hermits.

It wouldnt hurt. Im actually going through the same problem right now, I took the rocks out when I did a water change and used the old water in a bucket along with a toothbrush and removed about 90% of it. It takes a little while though hope you have about an hour to spare.

Since you don't have anything in your tank, take the LR out and scrub a dub-dub and do frequent 30% water changes. Hair algae is common at this stage and is referred to as "new tank syndrome". Or you could dose vodka and MB7....JK JK JK

tuxedo urchin will eat all of that
