any of the above can grow zoa's, ive used mh with pc, mh with t5, t5's with several color combo's, and several led unit's. i honestly cant say one grew then better then the other
i think alot of time people want to attribute lighting higher up then what ive found personally to get best growth, which is the basic, water quality, and flow.
i know mucho has been looking for answer's on growth for years but there is so many variable's, type and condition of water where they origanally came from, whether it was someone else's tank or the ocean. do you spot feed your zoa's ? do you use any additives ? if i had the space i would love to do a side by side comparison with 1 colony of zoa's break into 5 pieces and stick each piece in a different 10g tank, just run a hob filter and use 5 types of lighting, so that it is all equal except the light
Oh, I agree 1000%, I have never had any problems growing them. I just like discussing topics that everyone can contribute to and learn from.
You are so right, there are many variables which contribute to growth and lighting is but one of them. Hey who knows, someday you might have the space to do that side by side comparison mate.:beer:
