So I just picked up a 14 gallon biocube for my sea horse. It needs a good cleaning with vinger so I'm going to do that now. Once I clean it with vinger and rinse it out do I need to do anything else to it or can I fill it up with water?

Another question is I'm going to be rinsing the sand that came in the tank and then placing it back in there to use. I'm using live rock already. If I take 14 gallons of water out of my display tank that has great water peramters do I still need to wait for a cycle?
