does anyone scrub new liverock with a brush

[BCOrchidGuy]

I read somewhere that the best way to get pods growing in your tank was NOT to scrub your new rock. Decaying sponges etc are all excellent for starting a pod culture and I've found some very cool stuff growing in my tank that I never bought, right now I've got a small area of something that looks like coraline algae but it's raised, like flower petals, like a pink encrusting merulina... hard to describe but it's sure pretty.
