Help!! 1st Aiptasia appearance!

[Bill S]

Freezing is a great option. That won't kill any good bacteria you've developed. Since there's nothing else on the rok, you should be good!

[Mr Cob]

I use Peppermint shrimp...they have always worked for me and have never bothered any of my corals.

[JimD]

Inject them with liquid calcium, works great and wont hurt your water...

[Crazyeyes]

Yes be careful of the bristle worms and aptasia if you cut either one they will multiply. A answer to the bristle worms to get wrasse, and aptasia is either the chemical, or a butterfly fish or the peppermint shrimp.

Kind of late on this but since you are just setting it up and sounds like nothing is in the tank yet I'd just take that specific rock out and kill it out of the water. Torch it, freeze it, whatever you want but give it time to completely die before putting the rock back in. If you have other rock whatever does die off will regenerate from you other live rock.
