I really believe your tank was jump start cycled due to the live rock. Wait a few days or at the most a week, then test again, if all is zero you should be good to go. Check the ph and buffer it up to 8.2 with Kents super buffer.....check your ca if you can and your alk. This isn't imperative but I think your salt mix may not have enough if the ph is low like that......think about switching to a more consistent salt mix like instant ocean or reef crystals and if feeling rich Tropic Marin ..... these salt mixes are well tested and seem to be more reliable as to parameters.....I am not saying yours isn't just that it isnt as common of a brand.
