Replace rock or clean?

[saltlife97]

Hey guys I’m starting up my new tank and sump , don’t know what I should do , I have about 80lbs of live rock from my previous display tank and it’s covered in hair algae , is there any east way to refresh these or should I put them in the sump and buy new for display?

I'd opt for clean.

80 lbs of rock is a lot of money spent on, well, just rocks.
I would clean them.

Clean it with a stiff brush
