I would still not be too concerned about going to the store. If this was indeed a droplet transfer from an infected LFS tank to your clothes and from there to your tank then it was a freak coincident - pretty much the equivalent to hitting the Powerball jackpot.

BTW, Amyloodinium is an algae and as such, it can live for a good while (weeks to months) of photosynthesis alone. But this also provides a way of keeping it in check by unleashing predators like rotifers, feather dusters, or sponges on it. This may not be too useful in a fish tank, but it may help to eliminate free stages in coral and invert quarantine systems.
