In your original post you mention there are no fish in the tank, and that you do not intend to put fish in the tank for a while.
I might argue to let it run it's course. The concern with hitchhikers on plants is primarily centered around parasites and nasties that will harm your fish. But, by and large, parasites and nasties without fish hosts will die out within a couple weeks.
You don't mention if this is a sterile high-tech planted tank or a natural low-tech (Walstad) style tank. If the latter, I don't know of any way to keep beneficial creatures out of it. You will eventually end up with detritus worms, seed shrimp, and random pond life once the tank is mature. I don't know how they get in there, but they do. And by and large, you don't care, since they are all part of a healthy life cycle and natural filter.
So, I guess my thoughts are, bad things will die if there are no fish, and good things are going to show up anyway. So, if no fish, maybe just let it work itself out.
