No, just open the FW tank valve and you will be good.
I am assuming that you ran the antifreeze through ALL of your pipes, including the exterior shower, the sink sprayer and toilet sprayer if so equipped. If that is true then you should open your low water valves and either drain everything out or at least make sure that you have the pink stuff at these valves. I personally would drain all the pink stuff through the low water valves. The antifreeze has displaced all of the water. It serves no purpose after that. Just my two cents.
