Detritus on live rock

[monti1]

?I was just finishing up a water change on my tank and noticed a good amount of detritus building up in the crevices of my rock. It is a fairly new tank so I am still dealing with algae out breaks. should I take the rock out of the tank and shake off the detritus in made up saltwater? I was thinking about re-aquascaping the tank to elimate dead spots now that I have my new powerheads. I could shake off the rocks then. What do you think?

Thanks,
