How many hours of light does a refugium need a day to grow micro alage? like chaeto. thks

Many including myself run a reverse 12 hour lighting schedule. Mine is on at Midnight & off at noon. Supposedly it helps keep the ph up a little at night.

Best bulb I've found so far is a 6500K Daylight CF bulb that looks like a flood light bulb. I bought it at Home Depot.

I have the same set up and 6500k flood light $15, you will notice the grow after each day

I keep mine on 24/7 as I have an underpowered skimmer... I used to have a bak pak w/o a sump/fuge and it worked great but now I have an extra 15 gallons and the bak pak is in sump while I wait for my new octo extreme 160... Once that bad boy goes in I'm going to go to the reverse lighting schedule 10 hours DT lights 14 fuge...

But I have noticed that there is much less algae on the glass and I don't have to clean the glass as much and the small amount of HA I have in one corner is dying down a lot...
