are my lights on long enough

[lmh11706]

with my last tank i had my daylights on for 9-91/2 hours and always had more algae than i wanted

with my new tank i started a month ago im only leaving the daylights on for 6-61/2 hours and i do notice less algae and more color on the live rock but is this amount of time good enough for photosynthetic corals like polyps-zoas-and other soft corals

in fact any coral for that matter?

That's fine, but i would increase it for SPS. Hope that helps, Wiz

What kind of lights do you have? An important thing to remember IMO is that lights alone don't cause algae problems. I would attack the algae in every other way possible before jumping to reduced lighting.
