got lace rock for new tank???

should i scrubb these guys down with some water or something before i throw them in the tank???? the base rock will turn live after some time right???

 

It's usually a good idea to rinse it off to avoid getting any dust or dirt in your tank I usually use some tank water from a water change to rinse it. Yes it will "turn live" after awhile

 

will that kind of answers my question, I went to my LFS and hand selected 4 pieces of Lace Rock for the many deep holes, they will work perfect for putting my Coral frags in to, I was not sure if the Lace Rock would be reef safe or not, I guess it is.

 

There was a good thread on it awhile ago that I tried to bring back to life to see the long term success with it from the OP but had no luck. As long as the Lacerock wasnt exposed to any medications or chemicals from previous use (in SW or FW) it is safe. The main debate on it is how effiencent of a filter can it be being that it is extremely dense compared to reefrock. Does this impact biological bacteria colonies and the nitrogen cycle? Certainly, but exactly how I never found any scientific studies. The last part is appearance, this is completely up to you if you like it then thats great it works for you, if you dont then dont use it.

My own opinion and not from any scientific study, is that in all the FW tanks I have lacerock in I never saw a drop in nitrates from its use. I do believe it is to dense to adequatly be used as liverock. Many people have used it with success and it will eventually get covered in coralline algae. I am not much of a fan because I do not think it looks natural in a reef but what makes a visually appealing aquascape is completely up to the scaper

Hopfully some others will chime in to help Good luck
