OK so I have my tank all set up to go. I put in 50 lbs of live rock, 70 lbs of sand, skimmer and all equipment are up and running. I am going to be moving all the contents of my 37 gallon into the new tank(92 bowfront). The only problem is that my light went on backorder. It won't be here till the end of the week now. Is this going to cause a problem with my live rock that is in the tank already? Will I get some major die off and lose some corraline? What about the live sand that I put in? Will it die as well. If this won't be problem can I go ahead and add my clean up crew while I wait for the light to come? Thanks for any help.
