I forgot to add water conditioner in tap water..

I am a newbie for saltwater aquariums, I've used tap water and mixed "instant ocean aquarium salt" and placed it in the tank, after 2 days, I've added live rock, now I've been reading a lot on how to do the nitrogen cycle, so I've added the "Instant Ocean Bio-Spira Start Up Nitrifying Bacteria Aquarium Additive" into my 6 gallon tank (Fluval Edge), now I realized that I forgot to add a water conditioner before doing all of this...can I add this after the fact? or do I need to start over? Thanks for the help
