Water flow for leathers -- too much?

[DanInSD]

Hi there. I've got a 120 gal mixed reef (mostly mushrooms, zoanthids, LPS, and xenia). Water flow is from a 1250 gal/hr pump that does filtration; and then a VorTech powerhead inside the tank.

I just got a light green sinularia (I think) from the LFS. I was told "high light, high flow". I put it about halfway up the tank, and to the side of the main flow the VorTech (the direct flow is crazy-strong). It's getting fast "biased random" flow (more from one direction than the other).

Since we put it in yesterday, it has "squatted down" (compressed/shrunk). IME with other corals this is sometimes a reaction to more light (I'm using 8x54w T5's) but can be "too much" flow.

Thoughts?

Thanks,
Dan
