Hello,

I have a setup with halide lights. What is the recommended duration that i should have them on. I have a programmable timer.

Thanks

Most people do 8-10 hours a day.

[welcome]

i was running mine 12 hours a day but have noticed some bright green starting to form on the rocks at the top of the tank so i am going to cut my photoperiod down a little over the next couple of days!

I run 3-11 actinics 4-10 halides no algae issues and temp flucations and my corals seems to be doing well with that lighting period

I run mine 8hrs per day. Growth is awesome and no issues.
