You should be ok with over skimming your tank. Keep in mind though that they may not spread, or expand as much in a tank that it super clean. I have heard that some of the barebottom, UV, ozone, super skimming reefers have a hard time growing zoas. I have seen tanks with a high skimming, high flow, and light combination grow zoas well (these were mainly SPS tanks).
If I were you, I would try it out with some cheaper zoas before you go out and buy some more expensive zoas.
Does that reply help?
