I just switched radiums 20k 400w to hamilton 10k 400w. I know the par was 90 on the radiums and 198 on the hamiltons. Should I shorting the light cycle to acculmate the tank? Is there anything else I should do to help the corals with the switch? Thanks

I would keep the same total hours, but place a piece of eggcrate over the tank for a few days so things can acclimate.
