Yes, I believe so. I would not keep them on more than 12.

If the algae is growing, cutting back is not going to stop the growth. What's your work crew consist of?

Smaller tanks can be finicky. Frequent water changes. Check out The Detritus Attack Packs on Liveaquaria.

You don't need that long a photoperiod. It's a waste of electricity, lamps, and can effect livestock.

In the Caribbean the Sunrise, sunset, dawn and dusk light cycle averages about 13h 41m.

In my tank the T5 Actinics run 6am - 2pm, MHs 2pm - 6pm, back to T5 Actinics 6pm - 8:30pm
Moonlights 8:30pm - 6am

My tank flourishes. My corals are healthy and my fish are healthy. I get to enjoy my tank in the evenings, that's why I have it. Good filtration, water changes, and giving your tank the attention that's required is key.
Tanks have personality.

if you have algae its probably more of a nutrient issue rather than a light issue

That's a great light schedule. I'm going to try that as well.

What are you using for moonlights? I would like to put some but I think the blue LEDs I have is too bright.

The moonlights I have are built in the Hamilton light fixture. I have a 6' Cebu.

On all my tanks I run my blues from 9 am then my whites come on at 10am. The whites go off at 8 pm and the blues off at 10pm. That schedule works for all my tank, coral or not and I have no algae issues at all. I've considered cutting back my whites even, so excessive light isnt usually necessary unless you have the corals adjusted to it I guess. lol

I have been having a problem feeding my lps. Seems like I can never see when the tenticals are out. I have only been running my blues for one hour. 2-8 all on 8-9 blues only then all off. Do you think I would need to leave my blues on longer to help this? My closed brain and chilli coral are my problems.

Some feed at night. Take a look late at night early morning and see if they are out then.
