Anyone run tests of PAR value over corals?

[WingoLED]

I want to find the consensus on what's the minimum par value for general zoa need.

Of course, we know there are many exceptions. Let's focus on the so called common zoa.

I've done par values over my corals and around my tank, never directly over the zoos. These are my assumptions

I would put the min. Par value at 50. If you want some growth.

I bet you could sustain some around 25. Such as nuclear green palys most would die.

Feeding can also make up for lower light levels, but mine are in areas that run between 75 and 100 for the most part.

50 seems to be as Low as I can go and still have happy zoas but you might be able to keep the odd zoa a little below that. For good color and growth I normally run 75-125
