how much light in this set up?

[jbjack]

i have a 28g nano with power compact lighting. its the 104 watt quad light from jbj. its half actinic half i think 10000k, but can not do just actinic or just 10k, its all one quad light. also have moon lights. Right now i have it schedued like this:

3 hours in morn the moonlights come on, then the main lighting for 7 hours, then moonlights again for the next 6. then 8 hours of darkness. i want enough lighting to keep coral healthy while extending the life of the light, and keeping algae at bay.

also during darkness in tank, the back panel where i have chaeto has an led system (nano glo) turned on.

so whats the min length of main lights on for these corals?

i have:

frogspawn, different zoas, palys, toadstool, candy cane, mushrooms, fuzzy musgrooms, ricordia, aussie brain, aussie acans, aussie duncans, open brain, pineapple, clove polyps, and 1 i cant remember what its called, help me out lol, its tiny little purple flowers all close together that stay flat to, and spread on rock.

is 7hrs enuff?

thanks

None of your livestock is particularly light demanding, so 7-hrs should be fine. When I saw keeping higher light stuff (SPS and clams) under that 105w PC I was using a 10-hr photoperiod to make up for the lack of intensity. It worked reasonably well.
