light acclimation suggestions
How much caution and what measures would you take with upgrading from 250w to 400w Iwasaki's? I just bought a setup off Marc. Bulbs are 9 months old but I don't think Saki's loose all that much par. How careful should I be.
I was on a 12 hr photo period before. 10hr MH with 12hr 220w VHO actinic. My 400w Bulbs are at 8" off the water.
