should i be worried.. bryopsis in new tank

1 month old tank. 70 lbs LR from established tanks + 60lbs base rock. LS. 4 sm fish. I have bryopsis growing on some rocks and over glass. Not a lot (yet). What if any action should I take besides manual removal and keeping Nitrates and Phos down? Mag increase or not it's not really that bad right now but I don't want it everywhere. -- If I'm not mistaken either hermits or snails have eaten quite a bit of it.. does this happen or were they eating hair algae mixed in with the bryopsis?

 

sorry, didn't read the sticky thread.. pretty much answered my q's. n
