It depends of the params and the types of zoans.
The best performances I got is with a kind of reddish brown zoans, they spreaded like 1-2cm/months on a live rock.
I also have mix of red and green zoand rocks. The red ones tend to spread better and faster than the green ones, they gros like 0.5 cm/months on frags rumble rocks. I also have radioactive green zoans, they don't really spread quick, but they get more density. I also had kind of orange and blue zoans, they never growed/spreaded and also they got zoa pox disease.

Adding a bit of liquid phytoplankton to the water column once or twice a week.
For the water flow, I never any issue both with strong or ow flow, I would say give them just a bit less flow it takes to keep them closed and they'll be happy. If they unglue from the frag/rock, it means flow is too strong.
Some zoans are REALLY toxic, if you're not sure of the specie, at least wear protective glasses when manipulating them, they can spit toxin when they're out of water.
