So im looking to buy one or the other but I am not sure which to go with and my searches have come up short. I have a 72g bowfront with black gravel (small gravel), a homemade yeast-type CO2 system, 6 cories (incase one holds better against them) and dual t12 bulbs which tomorrow im getting new bulbs. Which should I go with, 6700 daylight or look for a 10,000??? So which of these 2 will carpet easier/better ??? Would like opinions here :help:
