.010 is too high to be reliable. It does work fine if you want to combine it with copper or formalin or whatever, but .008 is what you'll need to absolutely wipe it out without meds. 007 or lower is not required or recommended.
A series of freshwater dips will also be very helpful, and add some Kyolic garlic or reef-made garlic stuff to the food. The dips will keep the fish alive long enough for the other stuff to do the job.
If you have livesand in the main tank, then you'll have to leave that tank fishless for about 6 weeks to be reasonably certain the parasites are all gone. If that isn't possible, then install a powerful Ultraviolet unit instead to deal with whatever swimmers you miss. Otherwise, either remove all your sand or brutalize it with the low salinity.
I certainly hope you've learned your lesson about quarantine. One of the first things a new saltwater keeper learns, and usually learns the hard way, is that quarantine is not a luxury in saltwater, but a necessity.
