For me i had too many variables, i switched from a 2 bulb 10k and actinic, to a 4 bulb 420/460 and 700+ lights, different fixture and programming. I was running 12hrs on and 12 off, now the auto programming on the aquaticlife fixture runs the 420/460 from 8am to 8pm, the 700+ from 10am to 5pm and the moonlights from 8pm to 11:30 pm. I have notice a large increase in my coral algae growth, almost no nuisance algae at all and all my corals are getting more colourful. Like i said though, too many variables as i also switched to RO water, started testing/optimizing chemistry, added a refugium...on and on and on. If everything is equal, then the lights could be the reason, but too many other things have also changed. when i started my tank i started a journal and keep track of all my water changes, dates of testing and results, even when a fish dies. This is the only way imho that you can say one thing or another really had an effect.
