I just wanted to ask, how many people running metal halides have really noticed a difference in growth rates when changing the bulbs they run?
When I changed from 6500k Iwasaki to an AB I noticed zero difference in growth rates and noticable improvement in color.
I had a buddy that claims the same thing. It seems as long as water quality is consistent throughout the day my corals grow most consistently. When I start getting flucuations, growth slows down.
I've seen the 250watt bulb comparsions on RC, most of the time Iwasakis win hands down regarding PAR, but how much is really nesacary for good growth? My Ab's seem to pump out enough to make most digitata frags grow insanely fast and put nice white tips on my acros. I'm waiting for my coralvue to burn in to see how similar corals react to it's lighting, as it appears the coralvue has less PAR than the AB, although it sure does visually appear brighter...
Anyways, just some thoughts, looking for input from anyone.
