That would be fine, but there is no need to. You will get a NH3
spike anyway from the rock. but they LR
will cycleyour tank faster. did you get any ls
from them that helps too. Don't worry about the critters on the rocks they are very tough; else they would die during the shipping. I had a spike and everything lived Corals, feather duster, star fish and urchins. Just make shure you keep the NH3
levels low by doing water changes. good luck.
I am going through a mini cycle right now from adding some rock and I a worried about my fish now. but my other little guys should be fine.
